used the new checkers

With the Double Star checker documents at the ready, I scanned the sketches submitted with a Double Stars certification application. Handy! Comparing was quick and fast!

made another checker

Made another checker, once again, using SkyTools 4 Visual Pro. This one for a rotated view, perhaps presented by a Newtonian telescope (or a refractor straight-through!). Used the other version as a template. So, hopefully this and the mirror-reversed version, will ease and speed the checking of the submitted Double Stars certificate applications.

that ends well

Appeased a youth and his family. We look forward to receiving a new keen youth member into the RASC community.

noted clouds (Bradford)

While curbing the bins for the next morning pick up, I noted the sky. Not pristine. The spotty clouds were probably thwarting efforts by some RASC members at Glen Major Forest. Too bad. Tagged Jupiter over the roof of the house as I walked back from the street. Pretty for west actually, perhaps west-south-west by the compass.

showed how to use the web interface

Helped an ObsComm member with accessing the forum/listserv via a web browser on a computer. Looks like they are not getting emails delivered to their tablet for every forum post. This will let them compare and if we need to, collect forensic data.

trained new staffer

Met one of the new RASC office staff, along with the exiting membership coordinator, and the Exec Dir. I was able to offer some "training" of the certification handling process, supported by my swim-lane flowchart. I think this will streamline matters for the Observing Committee volunteer and the Toronto office staff.

updated the checker

Updated the Double Stars certificate checking document. It now features the target pair description from the Supplement along with the individual magnitude values. It also shows the B-V values!

This completes the work on Mirrored version. Now onto the Rotated one...

attended a planning meeting

Attended a planning meeting for the SCOPE newsletter. Odd. The organiser did not actually book anything in a virtual meeting tool. Assuming. Which then made for a late start! And the new editor did not show up. Broken.

another council meeting

RASC Toronto centre members have been invited to another council meeting, this time to review the matter of land acknowledgements in our future meetings and events. RASC national representatives will be on hand. The official notification PDF file sent out had typos in it. Can't even get that right. But I believe it is on Tuesday 5 October at 7:00 PM.

met with E.D.

Had a good chat with the Executive Director. Did a bunch of post-mortem and ideation for the future. Hopefully we will have the observing certificates... issues... sorted very soon.

reviewed a draft

Reviewed a draft of a new RASC observing program. This will be neat!

sent apologies

Issued over 15 apologies to observers who have not received their RASC observing certificates.

asked to be removed

Asked to be taken off Sissy Haas's mailing list. I can't take it anymore.

CAO information to review

Received matters for the planning of the fall maintenance at the Carr Astronomical Observatory. 'Cause I care. Also received some pixel-y HUGE images. Oh my.

notified of council meeting

RASC Toronto Centre councillor Ed T sent a message on the forum informing members of Council's next meeting. Council will meet Thursday, October 14, at 7:30 PM, virtually via Zoom.

switched pants

Ooh. I ate too much at birthday dinner. So, once home, I switched to my new George Men's Jersey Pajama Pant with stars and constellations. Gift from Rhonda.

Comfy.

put on socks

Headed out to dinner. So, of course, I had to try out a new pair of NASA socks by Mad Engine. Chose the grey-black pair out of the three pack. Orbit Day gift from Rhonda.

did some training planning

Did a bunch of Stellarium training course planning. Arranged for introductory courses to be taught by the other trainers. I'll deliver an intermediate in October. And I circled a date to run the webinar/Q&A session. Been almost a year. Oh, and suggested some dates for the level 3 advanced rehearsal test run...

we got lucky

Looks like the Sun's gone out and it's raining again. We got lucky last night at the DDO, this thin sliver of clear skies at night. I'm going to listen to the sky-water falling down...

late checkout from DDO (Richmond Hill)

Helped at the Up In The Sky event from the David Dunlap Observatory... yesterday? Yesterday.

I headed down in the late afternoon so to have a good amount of time to set up and prep, feeling a little rusty, and wanting to work on my own. Quite cloudy during the trip down. Maybe this wasn't going to work...

Then some slack time.

When Denise arrived, I had the dome open, cooling fan running, Stellarium running, adapters out, Visitor eyepiece ready, finder MallinCam going, my laptop John Gomez going, my new USB headset at the ready, sidereal time set, upper door open (after some persuasion).

Received Andrew's MallinCam Universe.

The skies were perfectly clear!

Targeted Saturn quickly but the camera image was breaking up. As I tried to sort things on my work, I was awarded a BSOD for my efforts. With about 30 minutes to go. Stress I didn't need. While I waited I fired up the DDO ASUS laptop but neither Denise or I could remember how to log into it.

Finally Win 10 came back and all was well. Received the VDO Ninja information from director Andrew. And suddenly I was on, talking about Saturn, the second largest gas giant in our solar system.

Rick and Claudio and Ron took turns talking through the evening. 

After Saturn I headed to Albireo. When I sat down and put my headphones on, they were transitioning to me. Yikes. Wasn't ready for that. So I quickly found my notes and talked about double stars.

Then I went to Jupiter with the 23 ton telescope. And was ready when they tossed the football to me.

Took an audience question.

And then I was done. There was some talk about me doing another target, beyond what was scripted, but I suggested others should show things. Even Ward was able to share an image, his comet C/2020 F3 (NEOWISE) shot from the summer of 2020.

This gave me time to work on the DDO portable computer. Got logged in. And discovered the MallinCam Universe software had never been installed. So I did a near-field Bluetooth transfer of the control app and the driver. Swapped out my computer for the RASC unit and connected successfully to the camera.

I tried viewing τ (tau) Cygni.

When the show wound down, the lads from the lawn came up to celebrate and do some quick training and refreshing on the 74-inch.

Claudio in particular wanted to try his cameras. We spent a lot of time experimenting.

During this, I tried to improve the focus of the finder scope with its MallinCam. That worked, the Ring Nebula obviously improved on the TV monitor. But as I locked down the focuser, the little refractor moved in the ring holders. I spent the rest of the evening trying to realign it. Frustrating. I still think its off so I'll have to revisit that...

Denise and I closed out the dome at 2:42 AM.

I gave her the my 3D model of the telescope printed by Steve. She was thrilled.

Seat of the pants, tonight. But Denise was happy. First time I went to three different targets in the same show!

Wow. Long night. Home after 3 AM.

checked Teflon

Finally had look at the Teflon procured from a plastics co. in the GTA thanks to Tony. The stuff is heavy!

Three pieces. The long rectangular is 3/8"; the two squarish pieces are 1/4".

• 15-3/8 x 3-1/4
• 7-3/8 x 4-3/8
• 8 x 5-7/8

I can now finish my Dobsonian base build...

And fix the big Dob from the DDO.

to fly the 74

There's an Up In The Sky event planned for Friday evening. It's an online event at the David Dunlap Observatory. I'll be operating the 74-inch telescope with camera attached. If the skies clear, we'll show some live views of astronomical objects.

See the RASC Toronto Centre web page for more information.

There are still tickets availalbe at the Richmond Hill web site.

Sorry! Registration is closed.

plus 10k

Holy cows!

My barn door tracker YouTube video has over 10 000 views!

That is so wild.

not again!

The Toronto Centre president again said the CAO house could not be booked by members. Ralph and I tried to correct this messaging in the YouTube chat. Sheesh.

The upper level can be booked by one party.

the terrifying Universe

Enjoyed Dr. Leo Yvonne Alcorn's talk on Lovecraftian fiction with scientific content for the day.

She took my question. I asked if she had a Flying Spaghetti Monster bumper sticker on her car.

She didn't. But she wants one.

received October Journal notification

Member Services sent out the notification for the latest Journal of the Royal Astronomical Society of Canada. The October 2021 issue is out.

Aurora on the cover. Aurora prediction software in my column.

Katrina discusses star culture in a colonised world. Dave C talks about seeing gegenschein in a peculiar spot. John acknowledges CASCA's 50th year. David L looks back on Carolyn Shoemaker's life.

My Binary Universe column is about one of the better aurora monitoring apps, Solar Monitor, for the iOS platform. Not perfect and a little pricey but helpful with an information-packed main screen and timely notifications.

The Journal or JRASC is available to the public. Download it now. Enjoy!

taught Stellarium intermediate

Delivered another Stellarium level 2 course. Good crowd. Good questions. My mount behaved just fine!

imaged STF 2146 faster (Halifax)

Shot double star HD 156162 aka STF 2146 aka SAO 30299 again! Faster still! Twice as fast as 12 days ago. Also switched to the SBIG camera. In Draco.

Luminance only, 0.1 seconds, 12 subexposures. FITS Liberator, GIMP.

Caught it in stunning conditions...

Well... I don't think AB is round.

This is the shortest value allowed with the BGO rig. So I cannot shoot any quicker. That's it.

§

WDS entry updated! There's no B. The tight companion is near C. See the 29 Aug '21 blog entry for details of the change.

posted Sep '21 doubles list

Prepared my double star "bulletin." It is a short list of suggested targets. I shared this on the RASC Toronto Centre forum. I post here for all.

§ 

School's back in, sorta. Summer's over, sorta. One thing for sure: the Moon is back, big and bright. And that means you need to shift to planets, variables, and double stars.

Here's a short selection of doubles and multi-star systems from my life list, ones I find impressive and interesting.

star	also known as	alternate catalogue(s)
β Cap	ΣA52, Dabih, 9 Cap	SAO 163481, HIP 100345
ε Equ	Σ2737, 1 Equ	SAO 126428, HIP 103569
HD 177904 Aql	Σ2449	SAO 124265, HIP 93822
HD 203320	S 786 Cyg	SAO 33323, HIP 105298
V402 Lac	HJ 1735	SAO 51698, HIP 109354

Have a go. See if you can split them and detect colour. I hope you'll share your discoveries.

Notable double star designations:

Σ = F. Struve, STF

ΣA = Struve Appendix I, STFA, Σ1, ΣI

β = Burnham, BU

HJ = John Herschel

learned of the second!

Wow. Heard of another RASC member completing the Double Stars program. A Toronto Centre member this time. Yes! So exciting!

made a new calculator

Made a new, updated, hopefully easy-to-use online spreadsheet for Melody to use. It's basically fill-in-the-blanks and it should yield a good separation value for a double star.

It's pretty snazzy.

Onboard instructions and notes.

Constants sheet for the Earth's rotation rate and the sidereal time factor.

Supports variable Linear Scale divisions, say 50 or 60!

Prompts for a dozen drift times, taking the average.

Prompts for the star's declination, so to compute the speed of the sky.

With that, the Scale Constant can be determined (per my proper formula).

Supports four scale constants with and without magnifiers and reducers.

Finally, prompts for double star pairs and their separation in tick marks on the Linear Scale.

Computes the true separation or ρ, rho for a dozen pairs.

Hope they like it...

helped Bruce and Melody

Chatted with Melody and Bruce about their new Meade Astrometric eyepiece. Told them to not use Meade's faulty instructions. Explained that the speed of the sky was a factor. Demo'ed the process with my new spreadsheet. Readied to invite them to the shared file...

did some math

Another interesting journey...

I started a round of research to learn or verify how to measure double stars with the Meade Astrometric ocular with its illuminated reticule and its central Linear Scale with 50 divisions.

My experience is with the Celestron or baader planetarium Micro Guide (now discontinued) with 60 divisions. 

I had a bad feeling that my method and separation calculation would not work. I wanted to help Melody learn how to use hers but feared my technique would not apply.

"Let's start from scratch," I thought. 

Did some broad internet searches.

Landed in a Cloudy Nights thread started by Jeremy Perez no less. He was trying to learn his Meade Astrometric eyepiece. Perez developed his external protractor. People recommended Tom Teague's method and Bob Argyle's book. But in the end, it didn't reveal to me a formula.

Then I found a thread in the Stargazers Lounge. Davey T asked how to use his Meade (though he showed a reticule image for a Celestron) back in the spring of 2015. William aka Oddsocks gave a procedure referring to a star at zenith. A day later he backtracked. On reading Qualia's notes for a Micro Guide, he realised his instructions were wrong. But he had simply relayed the notes from Meade.

It is strange how you read something from a "respected" manufacturer and believe it must be correct...  I realised the published linear scale calibration method in the Meade document is garbage!

Oh my.

The Meade document is useful in other details but the linear scale calibration method can be ignored unless you are living on the equator

So I still did not have a formula.

But now I was getting more nervous for Melody's sake.

I read Qualia's blog post on measuring doubles and Jovian moons with the baader Micro Guide. Some pretty good notes.

Finally, I found a formula for calculating the drift’s scale constant.

S.C. = 15.0411 * T.avg * cos(Dec) / D

where:

• S.C. - Scale Constant
• 15.0411 - Earth’s rotation rate per hour in degrees
• T.avg - the given star’s mean average drift time
• cos(Dec) - cosine of the star’s declination
• D - number of division on the linear scale

I compared this to my formula:

ρ = D * T.avg * SidFact * cos(Dec) / 4

where:

• ρ - separation in arc-seconds, rho
• D - divisions or ticks on the LS, in decimal form
• T.avg - average drift time in seconds
• SidFact - sidereal time factor or 1.0027379
• cos(Dec) - declination of the star, in decimal form

Some marked differences that unnerved me. Oh boy.

Couldn't seem to find the source for my formula...

Still, there seemed to be something going on here. I could not see it at first... But after a lot of head-scratching and noodling and staring and some home-made spiced rum, I realised what it was.

The 15 (and change) value divided by 60 divisions gave 1/4 (close enough from an aeroplane). That was what I was using in my formula! Whew. They were essentially the same. That was a big relief. So I made a new universal formula considering everything.

S.C. = ( RotRate * T.avg * cos(Dec) * SidFact ) / D

And then you multiple that by the counted ticks on the scale to get ρ, of course.

I really like this new formula since it will work with any reticule regardless of the divisions and as it integrates the sidereal time factor too, which I also cross-checked.

That's produced by dividing 86400 (regular day in seconds) by 86164.0905 (a sidereal day in seconds).

Relieved.

Along the way I could not find an official PDF on the Meade site for the ocular. I could only find it on one of those suspicious manual sites...

But I finally saw it with my own eyes. Step 4: Aim the telescope at or very near (within +/- 5°) the zenith (perpendicular to the ground).

Later they said to take three timings. Ugh. More bad advice.

And there it was in writing, after the step-by-step procedure. Stars at or near the zenith move across the sky at 15 arc seconds per second (sidereal rate).

No. Wrong. Completely wrong.

Wow.

Oddsocks had called it. The true separation formula provided, ( T.avg * 15 ) / 50, would only work for observers at the equator.

So, again, the formula I made should be used:

S.C. = ( RotRate * T.avg * cos(Dec) * SidFact ) / D

This tells you how much real sky is between the tick marks on the Linear Scale.

Sorry. More work. And some trig. Sorry! But you'll get rather accurate results. I tested it in Stellarium with the Meade reticule view.

§

In follow-up messages with Melody, I learned that the instructions in her eyepiece box were like the ones I had stumbled across. New eyepiece from a 2021 sale with old bad instructions. Wow. It's amazing to me is that after all these years Meade hasn't fixed it or issued new information. Terrible.

content for NOVA

Arnold B reached out. He's helping with the national NOVA revamp. Good news. He asked if I might help with some Stellarium content. Let's talk.

tried rho Ori in a small 'scope (Bradford)

Back inside after the brief back yard observing session.

The plan was to spot the B companion to ρ (rho) Orionis, while I had a clear patch. I was concerned the double, in the new observing certificate program, might be too difficult for an observer with a small instrument. 

But I saw it.

It was challenging to be sure in the Meade ETX 90mm.

But it was definitely there.

With the Tele Vue 9mm Nagler Type 6, it was well beyond first diffraction ring. It was even visible in the old Celestron Plössl 26mm eyepiece. Detectable. The best view was with the Pentax wide view 20mm ocular.

Delicate.

I spotted C too.

B was to the EEN or EEEN, opposite HD 287611, very tight, much dimmer.

I viewed this double a bit before the meridian. Star hopped from Bellatrix. 

Pleiades up high.

Winter is coming.

Tempting to continue but... I was too tired.

I thought rather good seeing, average trans. But damp. Very humid. The grass was wet.

Pulled the Clear Sky Chart. Cloud cover: clear; transparency: above average; seeing: excellent; Moon: -22°.

Pulled the weather data from EC. Current Conditions. 11°C. Observed at: Egbert. Date: 5:00 AM EDT Friday 17 September 2021. Condition: Not observed. Pressure: 102.2 kPa and falling. Temperature: 11.3°C. Dew point: 10.8°C. Humidity: 97%. Wind: ESE 4 km/h.

So, a good experiment. 

No modifications needed...

suggested peeps

Chatted with Tony on some Nom Comm candidates in the Toronto Centre. It's that time of year...

heard the reticule eyepiece arrived!

Melody shared with me that her Meade Astrometric eyepiece arrived.

That was quick! From the UK. 

Then she said, "Now to learn to use it!" Indeed, I encouraged her to watch my double stars measurement video... 

But then I had a sinking feeling! Would the formula in my video and companion notes work?! The Meade as 50 divisions in the Linear Scale while the Celestron/baader has 60. Oh oh. I had a feeling that would affect things. 

This kicked off a round of research...

heard of the successful test

Ask Jo if he could test our uploader service in the Linux environment. He tested in a light-weight browser on Zorin Linux. Said it worked like a charm and was fairly fast.

checked the alignment

Shared some stills and a video from SkyTools to Chris V for the shadow transit near—not directly atop unfortunately—the Great Red Spot. Not aligned.

Checked in SkyTools 3 (manual) and 4 (auto).

checked another vid

Reviewed another video for the RASC Toronto Centre A/V team.

shared a thin design

Stumbled across an image of a "thin" barn door tracker design. Forwarded it off to Ian B who is starting to build his own.

processed trainees

Did some Stellarium training processing in preparation for the level 2 gig on 20 September.

asked for a DDO account

Submitted a request to national to reimplement an account for the Dunlap Observatory chair. Without it, she cannot access the RASC Toronto services...

fielded a query about a Moon photo

Yet another query came in via the RASC national web site observing form.

This time the person felt that in a photograph of the Moon they captured a shadow cast from another planet. 

Um...

I offered to look at the photo.

Unfortunately it was a shakey, hand-held, zoomed out, out-of-focus, low resolution, overexposed shot from a smart phone and saved in JPG.

Just an artefact, I argued.

Keep trying.

the very first one

Received the first-ever fully-completed RASC Double Stars certificate application! This just made my month.

chatted with the chair

Chatted with chair of the David Dunlap Observatory. Dealt with a number of open items. Curious of the status of a camera. Curious if I was needed. Recommended some other contacts for receiving notifications, for better coverage.

rejected some members

Issued rejection notices. Half dozen. General members continue to get confused and try to join the operational committee RASC Obs Comm forum workgroup thing.

relayed the good news

Shared some happy news with the RASC national team.

Harry from Uganda had found his Explore the Universe certificate and pin.

In fact, it had arrived on 8 April but the mailman never informed him!

Another loop closed.

proofed column

James asked, on the 9th, to review my Journal column draft, and respond before the 13th.

But Chris had my latest images. In his iPhone. In Richmond Hill. And he was at the CAO over the weekend. So I nudged Chris early Monday morning... A tad late.

I noted the wrong image was used for Figure 3. Sent it again.

And I provided an updated image for Figure 1.

Finally, I reworded some text in the Bits and Bytes section to be past tense.

picked up Teflon

I diverted during the drive home. Picked up purchased Teflon pieces. Heavy!

received more silica

More silica packs. Yes! My sister continues to put these aside for me. Thank you, thank you. Now. If anybody needs some...

Mask of Constellations

Received a little gift from sis.

An Ardene face mask.

With constellations! Cool!

reviewed her last observation

Melody shared another double star observing log page.

She said it took two early mornings to observe the B star... "very tiny, couldn’t see any colour..." Kept checking if she was on the right target.

I reviewed her notes and sketch for ρ (rho) Orionis, cross-checking in Stellarium on my Mom's Macintosh. Too bad SkySafari does not show it! Sheesh.

She got it!

At 40 degrees elevation, she viewed through 2 air masses. That said, the target at 45 degrees was about has high as it would ever get, for us.

The main issue with the dim companion star is that it is 4 magnitudes dimmer than A. So the primary star would overwhelm the view.

I also felt she tagged the C star in her sketch but pointed out it was the first one, not the second one, to the south-east.

It is a challenging target.

She made a remark about whether it would be visible in a small 'scope. I took that to heart. I only observation had been with a C14. I'd try with my 90mm later...

Her last required observation!

§

Checked the view in SkyTools.

All good.

in the line of fire?

No pun intended...

Received a query from a person from the general public via the Observing Committee web page form.

Subject: identify rock/metal fragment

Err...

The person said they had found a small fragment of burnt metal/rock in their backyard lying on top of the grass and assumed it to be space debris. They doubted it was a meteorite because it wa relatively light. It was very hard and she could not break it. She wondered if it was from the fireball seen on August 22 from Crystal Beach.

I responded. I declined an offered photo. I shared a link to the University of New Mexico web site, into the Geology department. Encouraged her to read the information there. I also told her that if it really is from space, she should immediately protect the object from contamination by bagging it. I also suggested taking it to the geological or geophysics department of a local university.

more IT support

Helped Chris some more with IT matters at the CAO. He rebooted the main router and lots of things started working better. Doesn't make sense but anyway. Then Backyard EOS wanted credentials so I shared those. It said it all worked. Most importantly, the network speed from the SLO was improved.

learned DSG history

On 7 September, Mike S filled out the contact form for the RASC national Observing Chair. He had a query about the Deep Sky Gems program.

Mike noted a change made to the list in the summer of 2020. The editor's note states that Levy 402 was introduced in place of Levy 226, however the numerical listing and detailed object tables both show Levy 226 present, and Levy 225 deleted. He did not see an update regarding this apparent conflict of information. He asked for some clarification.

Indeed.

I was pressed for time so I quickly acknowledged the receipt of his message. 

Today, I followed up with a detailed reply on his interesting observation.

I shared with Mike that in late-July and early-August, I started a dialogue, with the editor and content owner. I had concerns with the Deep Sky Gems list. It was when I personally considered pursuing the DSG program and did a deep dive that I started to see a number of issues.

In fact, on 1 August, I pointed out this very matter, 225 was missing, 226 remained. And curiously this specific question had never been answered! I did do not know what was intended but guessed it a simple transcription error. The editor meant to say that 225 was replaced by 402.

I thanked Mike for drawing attention to this matter in the Handbook. It needed to be reported and noted in errata documentation...

Then I went on. I told Mike I was anxious about list changes occurring every year or so and I had raised the matter with the Observing Committee. Others were not aware that this was happening. In particular, I wanted to know if it was affecting him. I was concerned that if he was working through the observing certificate that periodic changes might throw off the member.

§

Mike replied and shared his experiences with the DSG program.

Since first approved, a total of fourteen objects have been changed. That was an eye-opener.

He recommended that changes in the Observer's Handbook be reported by the Observing Committee when they report to National Council so there is an official record. And be included in a RASC Bulletin. I absolutely agree. He noted that if the OC is not being informed of changes being made, they should be. Yes.

These changes challenged him since 2010.

He also noted the original introduction stated there was only one object that overlapped with any other RASC lists. As he worked on the list he found three additional duplicates, one with FNGC and two with Deep Sky Challenge. These were reported and subsequently removed and replaced with four new objects in the 2013 OH. Eight of the fourteen changes mentioned above.

He agreed with my comment that an observer could be thrown off if changes are not clearly communicated. It would be beyond frustrating to think one completed the list to only be told one had to observe new objects. Yes, exactly what I'm trying to avoid.

Finally, he noticed the PDF list on the web site was outdated. A to-do item for us.

All that said, Mike said that he was really enjoying this program and wanted it to succeed.

§

I thanked Mike again. I appreciated the fantastic historical perspective. It would really help me out going forwards.

Then I made my key point. I made it clear that the Observing Committee is NOT going to make an observer go and observe new things if they worked from an older list. He definitely would not have to redo anything!

pitched some training

Sent a message to the level 1 graduates on the waiting list. Told 'em that we were planning to deliver a Stellarium intermediate level 2 course on the evening of Monday 20 September.

he let me in

Chris shared his double stars log spreadsheet with me. We disagree on colours for some targets. I wanted to collate his and Melody's observations ahead of updating the Supplemental document. Compare against mine...

learned how to script

I was bored so I taught myself how to do scripting on SIMBAD data.

I pulled the B-V values for all the double star targets in my RASC observing program! 

Earlier, I had built a spreadsheet with highly customised conditional formatting to show the B-V values with the cell filled with an appropriate colour. 

Fun.

This will help as I compare all the colour impressions from the early adopters including Melody and Chris.

I've no doubt some of my colour descriptions are wrong...

have you tried turning it off and on again?

Chris SMSed me. He was at the Carr Astronomical Observatory preparing for the University of Toronto Dunlap Institute "planet party." He started asking some questions about the network and related equipment so I put my tech support hat on.

He was not seeing the SSID for the network in the Geoff Brown Observatory. He asked if it needed a reboot. Nope. That unit died a while ago so no wifi inside the GBO. Hard line recommended.

He asked about the house wireless access points. They were only seeing the library and the furnace. What? I was surprised by that. The living room unit and the garage units (times 2) should be working. I asked for more information to get context. Like where he was located on the grounds.

In the kitchen. Then he shared that the house SSID was visible but not responding to the login. Authentication error or not connecting at all. Odd. I suggested he reboot the AirCube. 

He asked if the WAP was in the super's closet. Nope. Closer than you think.

A short time later, Chris relayed things were working. Good.

mark your calendar

Read the article by ars TECHNICA on the James Webb space telescope. They discussed its bona fide launch date. Coming up soon! Now it's on a boat to Kourou, French Guiana, to be perched atop an ESA Ariane 5 rocket. Circle 18 December 2021!

helped with Q&A

Helped backstage with the RASC Toronto Centre Recreational Astronomy Night (RAN) meeting. I did the questions, forwarded to the presenters.

pardon?

Rather surprised when the president of the centre said the CAO was closed.

returned to STF 2146 (Halifax)

Returned to Struve 2146 aka HD 156162 or SAO 30299. Still trying to wade through my confusing notes.

It's a triple. AB are very tight. In Draco.

Luminance, 0.2 seconds, 20 subs. FITS Liberator, GIMP.

C is the obvious bright star to the south-west.

I don't think I can split A and B in this image. According to SkyTools 4, the PA is 225° with a separation of 2.70"  (as of 1998). That angle is roughly the same as C.

The star west of A and north of C is J171259.2+540815 at magnitude 16.46.

First imaged this target on 25 Sep '18. Imaged again on 20 Sep '21, at a 1/10th of a second, oh, and with the SBIG sensor.

Is there a partner to C?!

§

WDS entry updated! There's no B. The tight companion is near C. See the 29 Aug '21 blog entry for details of the change.

pleased she agreed

Monitored the exchange between Edgar, RASC OH editor, and Matson, Naval Observatory double star rep. I was pretty chuffed. She agreed with all my proofreading suggestions.

received a list!

Computer pinged. New arrival in my inbox. How about that! A list of all RASC observing (and imaging) certificates issued to date.  My audit request had been accepted. Good.

imaged IK Peg for 2021 (Halifax)

The Burke-Gaffney Observatory was "back" from vacation. Yeh.

It imaged IK Peg for me again. Has it blown up?

Luminance, 2 seconds, 12 subs. FITS Liberator, GIMP.

I've been shooting this for three years now...

Captures, in reverse chrono order:

Looks the same to my little eye...

declined October TSTM

Mr Markov asked if I might have time to present The Sky This Month at the Oct. 6 meeting.

I had to decline. Too stressed right now. 

Did let him know, however, that I had been working on the next double stars presentation, measuring again, but with a camera...

asked for spectral information

Jumped into the SkyTools forum. Asked for help.

Explained I wanted to corroborate double star member colours.

Asked if I could list from the software stars with their spectral classification (when known, of course).

Author Greg said:

Spectral classification is a lost art, and it has little scientific use today.  As a result, with a few special case exceptions such as WR stars, only the very brightest stars have spectral classifications.  Because (B-V) colors represent the same color information and are available for much fainter stars, I chose to focus on the (B-V) color index.  The spectral class is shown on the Object Info, by the way, but just isn't available for many stars.  And fainter components of even the brighter doubles will often be missing the spectral class.

He suggested use the B-V data instead. It is more widely useful. 

I assumed the B-V value shown in a list was for the primary star. He essentially confirmed that.

But he did remind us that if we select a component star in the bottom right part of the dialog, the B-V for the selected star will show in the Photometry section.

That was good. 

But I moped that I could not pull the B-V data for the secondary and additional stars into a column in the app.

turned away another

There's been an uptick in external volunteer requests to the RASC Toronto Centre. I keep having to turn people away... Too bad. We could use 'em.

started testing ST4V

After an invitation from Greg, I started beta-testing SkyTools 4 Visual, specifically the Real Time mode.

Using the emulator, I will be able to shake things down on John Max. But I will also try to do full testing with John Gomez directly connected to the go-to mount...

clarified sources

Clarified notes in the pending Observer's Handbook regarding the observing programs offer and their ties to the Handbook...

helped with Zoom/Ninja

Participated in the rehearsal for the RAN RASC TC. Not called OBS anymore; it's VDO.

helped member out

Took a call from a new member at the Carr Astronomical Observatory, inside the locked gate, trying to get out.

magazine for Mom

Bought a copy of SkyNews magazine for my proud Mom. The Jul-Aug issue.

reviewed 2 log notes

Melody sent me some more double star log notes for me to review.

I thought she made a lovely sketch of 19 Lyn. I saw she was getting better at directions in the eyepiece. I complimented her on her position angles. She nailed it on HR 1887!

But she reported forgetting to drink her early morning coffee!

Nooooo!

asked about recognition

I've been perturbed by the lack of action from my local...

Spoke with some Toronto RASCals about land acknowledgements.

I thought it was a no-brainer but I'm wrong.

took a call from the VP

Charles Ennis, first Vice President of Royal Astronomical Society of Canada, phoned and answered my many questions about land acknowledgements and respectful recognition of indigenous peoples.

I was pleased to hear he's read the entire 500+ page reconciliation report.

We also chatted about asterisms. I made sure he had access to the team dropbox folder.

explained how to get a cert

Adrian forwarded a message from a RASC Toronto Centre member who had just read their SCOPE newsletters. They asked "How does one earn the Observing Certificate?"

I sent a response. Told him I was a member of the national Observing Committee for a number of years. Then briefly described the process. Said I was also happy to chat by phone or Zoom as it could be a big topic...

answered camp questions

Answered some camping questions for Charles Y ahead of his trip to Mew Lake. Hopefully things would go something for him and other like-minded peoples there.

dove into the OH '22

After a nudge from James, I made some time to sit down and proofread the 2022 RASC Observer's Handbook. I did a deep drive into the double stars section, specifically the Double and Multiple Stars topic.

Found over a dozen issues...

the pins

After another disturbing message, I indicated which RASC observing certificates are sent with a pin and which are not.

Maybe it is true: things are unravelling...

reassessed my plans

Cancelled my trip to Algonquin.

on it's way

Heard from Melody. For her birthday, her partner showed her a copy of an email. It documented the discussion with a company in Britain for the order of a Meade astrometric eyepiece. In fact, the order shipped. She was a pretty happy camper! I was excited for her. And I wished her a Happy Orbit Day.

how to proceed

With the Ontario government announcement today, I asked our A/V and speaker coordinators and the DDO chair and the CAO director their thoughts on places opening up, entrance policies, vaccine passport, etc.

We've started to consider in-person RASC meetings at the Ontario Science Centre and what we'll need to do.

Complex issues.

without our knowledge

The Observing Committee learned of a certificate issued without our knowledge. That was a little bit of a shock. That's not the proper process. We must be informed.

§

Later we learned of another!

Are there more?!

Time for a reset.

Just when I thought things were getting sorted...

§

It's disturbing that this only arose because the recipient did not receive the certificate in a timely fashion. Otherwise, this might have gone under the radar.

Obs Comm update issued

The Royal Astronomical Society of Canada Bulletin newsletter arrived, the September 2021 edition. Featured my bi-monthly update from the Observing Committee.

Shared the great news: we're easily broken the record for the number of certificates award in a year.

SCOPE newsletters provided

The editor of the RASC Toronto Centre SCOPE newsletter sent out a notification for new issues, times two! Lots of reading and catching up to do!

§

On the TC forums, I thanked the long time editor.

And the incoming editor!
