happy solstice
I was treated to another beautiful day, pleasant temperatures, low humidity, partly cloudy but intense Sun at times. It sure looked like people were getting thunderstorms and rain somewhere. Watched the setting Sun trace long angled lines across the grass. Around dinner time, I saw the waxing Moon before heading indoors—the mosquitos were taking a great deal of interest in me.
We're at the solstice, the June solstice, when the Sun is moving from Taurus to Gemini, when the Sun furthest from the celestial equator, in this case, as far north as it can go.
In the northern hemisphere of this little planet, that means the Sun will rise and set nearly it mostly northern extent, and will climb to its highest point in the daytime sky (during the day before or after). And that means summer time! Everything is flipped of course on the other side of the planet; it's winter season in the southern hemisphere with a shallow Sun angle.
The Sun is still...
I have always loved summer. I like the warmth of the Sun on my skin, bright blue skies, the green trees, all the fragrances in the air, all the animals and the birds and most of the bugs. I could do without millipedes and mozzies. I saw a marmot in the backyard a couple of days ago and I smelled the skunk. Today I listened to the cardinals and jays and robins and the hungry baby starlings.
The only thing I don't like about the summer is the short night. Really gotta be on your game during an astronomy session.
I am grateful for my nice backyard. I am happy to be healthy. Many don't have what I have. We gotta fix that.
I think I carry in my heart a big dash of optimism. I hope we're making this world a better place.
For all. For everything.

more errors in SkySafari
I've known of errors or issues with SkySafari but these comparisons brought a couple to light.
The first is a somewhat gross error. The target star in Cancer is HD 75646 also known as STTA 96 or CCDM 08520+2543.
Right away I saw it was wrong. The star is not HD 10958. They dropped a digit! That would be really confusing to the novice user and junior double star hunter.
That star is specifically HD 109584, the 6th component of the Σ1659 double star, i.e. the F star.
By the way, the separate value of 208.2" is pretty good. SkyTools 4 Visual Pro shows 207.4" as of 2002. The WDS (via Stelle Doppie) shows 209.4".
They could really use someone to vet their databases.

tried a dark horse
This is Dark Horse Palimino Red 2018. A VQA Niagara region product via the in-house Wine Rack. Made with Cab Franc and Cab Sauv grapes. Made by Dark Horse Wines of Niagara Falls. Inexpensive.
Lovely colour. Fruity nose. A bit more sugar than others but still pleasantly dry. And a pleasant taste, not harsh, hints of fruit, berries specifically, a touch of spice. I like it.
met Sarnia prez
helped Montréal crew
heard from Sim Curr
From David W with Rosalind H and Keiron S copied.
He advocated using the LiveSky tool for managing observing lists. I shared that I had (after a time) figured that out on my own.
He went on to say that one can share a list via the web and it makes a publicly accessible link. Good. I do see the broader benefits of the LiveSky environment.
I told the Sim Curr team that I had run into a lot of old documentation and confusing countermanding notes but that I appreciated they had limited resources and hadn't gotten around to updating things.
Near the end, he said this:
If you absolutely positively want to be a dinosaur, and "email" an old style observing list or host it on your own server (yuck!).
Wow. Don't know quite what to think of that.
I said that I appreciated the suggestion about email (such that it is) but told him it was throwing I/O errors. So that was broken. Perhaps they should not advise people to use that right now.
Just confirms my feelings. The company is incompetent.
It's a good app but their support systems suck.
If a user is not tech savvy, they'll be screwed with all the problems.

received an EtU from QC
uploaded FNGC lists
more time I can't get back
After hours of tests, experiments, reboots, researching, reading, I was still getting no where.
What I could do:
- copy .skylist files into the Android/data... files/Observing Lists folder
- use and edit observing lists on the phone
What I could not do:
- see .skylist files into the Android/data... files/Observing Lists folder
- and since I could not see, I could not copy
- email an observing list from within the phone app
So this created a bad situation. A very bad situation. I had edited and improved some observing lists that I now wanted to share with others. Can't. Can't copy or email the files.
The file visibility issue might be an Android problem.
But then, why can I see the .skyset files in the Saved Settings and the .skydat files in SkyData? Huh?
The I/O error inside SkySafari 6 Plus on Android is clearly a problem caused by Simulation Curriculum. Uh huh.
No answers on the Sim Curr community forum.
No reply to an email to Pedro.
No ideas from Chris.
No helpful explanation in the on-board help.
No helpful explanation on web-based user manual.
No answers over in Cloudy Nights.
Just tried the "cloud" LiveSky feature and it looks like it might work. Even that was not without challenges! Dumb dumb things encountered. There's a "download" button for each observing list, thank the Universe!
I am obviously tech-savvy with programming experience with an educational background and a good technical writer and I am aghast! It is mind-bogging how bad this whole experience has been.
And they wasted a bunch more hours today.
Simulation Curriculum is clearly in trouble.

discussed fibre matters
goose chase for custom lists
I'm surprised and not surprised.
Simulation Curriculum is messed up. Still messed up.
A key reason for coughing up funds for SkySafari 6 Plus today was to be able to receive custom observing lists from others, view them, use them.
So I went into the Search screen, swiped to the bottom, and I didn't see anything.
I was certain that's what I used to do.
Right?
I was looking for "custom" or something like that... at the bottom... if memory served.
So I appealed to Google. It suggested a page from the online manual.
Topic: Observing Lists.
In the opening remarks:
You create and access observing lists at the bottom of the Search view, in the Custom Observing Lists section.
I was right. Or my faint memory was right or consistent with what the manual said.
Tried again.
Nope.
Killed the app. Restarted it.
Nope.
Rebooted the phone.
No joy.
Skimmed the manual page and noted at the bottom the section SD Card Import & Export.
If you're using SkySafari for Android, you can import and export observing lists to SkySafari using your SD card.So I made a folder on my microSD as per the instructions and copied an old .skylist file there.
Checked the app.
Nothing.
Whiskey tango foxtrot.
I just paid money for this and it is not working right. Would I have to contact technical support and talk to a human? I loathed the thought of asking them for help. I'll do this on my own. Thanks for nothing.
Tried Google again this time indicating the "custom" option was missing.
Got a hit on CloudyNights.
DHEB, long-time user, had updated his SS6 Pro. Loaded a new list into the same ole' folder and it did not show.
Various people made suggestions but nothing worked.
So DHEB went to the Sim Curr community forum space for help. I read the thread.
Issues due to the Android, and the Android 10 security protocols.
But I wasn't on Android 10.
Still, I made a folder, in the internal memory this time, as prescribed by Ros.
Android/data/com.simulationcurriculum.skysafari6pro/files/Observing Lists
substituting for "pro."
Restarted the app?
Nothing!
Rebooted the phone again.
Nothing.
Scoffing shipwreckers! I was thinking I'd have to ask for my money back...
Then I selected an object, Achird from the Tonight's Best list, and tried to add it to an observing list.
Whoa, wait, what? A dialogue appeared saying it had been added to my observing list, the old one I had added! What? Where? How?
I looked at the bottom of the Search list again.
Nothing. N-O-T-H-I-N-G.
What now?
Fumbled around the Sim Curr web pages a bit. Noted a reference to Yahoo!Groups. What? Long gone, ya goofs!
Tapped the onboard help button, the circled question mark, in the Search screen.
At first, it looked like the same text as the online web page user manual that I had read already.
Bottom of the onboard page sported a section Custom Observing Lists.
Yes.
Spotted this:
In SkySafari Plus and Pro, you can create a custom observing list. To create a custom list of objects, first tap the Action & Settings at the top of the list.
What? Action & Settings? Where was that?
I checked the Search list. No...
Where was this Action & Settings for crying out loud?
What list?
That was confusing.
But then something clicked. From the Search list I chose the Messier list.
There it was! The Actions & Settings at the top of the Messier list (it was atop the Tonight's Best too but I had not noted it).
And inside the list's actions & settings screen, at the top, was the button to Make Into Observing List.
Crikey.
Tapped it.
A dialogue appear confirming the creation of the new list. Which I almost dismissed before readed the last sentence.
You can find it under "Observing Lists" after tapping the Observe button.
Observe button?! What's the Observe button?
Headed to the main screen.
Between Settings and Time, an eyeball, labelled Observe. Tapping it shows:
- Planner
- Observing Lists
- Observations
- Sessions
- Sites
- Scope Display
- Equipment
Uh huh.
So it looked like a big change, a big reorg, from version 5 to 6, with the new Observe button collating a bunch of related functions.
Excitedly, I tapped on Observing Lists and a familiar screen appeared. At last I saw my old 2020 observing list plus the new one just made based on the Messiers.
Finally.
Went back and checked the online manual on the web site. I'm not crazy. Mama had me tested. It definitely says observing lists are accessed at the bottom of the Search screen.
So old data on their web site. One of the easiest resources to fix. Online manuals were invented to replace paper manuals. Online manuals should never be out of date. Fix your web site! Fix your web site for your paying customers! You gave me an hour of grief.
Wasted my time.
Hey, Simulation Curriculum. Hire me! I'll fix your terrible web site.
So annoying.

ooh, that's why
I asked the Executive Director how this could be.
There are, and have always been, a few non-members who receive our email bulletin, having signed up from the website.
I was surprised. I had no idea. I just assumed the RASC Weekly and RASC Bulletin were in-reach channels.
Do other contributors know this?! I asked this question but it was not answered.
I suggested they include a sales pitch. That was noted.
I don't have a problem per se with it including externals.
But it means now that my notices on the RASC national calendar need to include the text "for members only" somewhere. If I'm lucky, that will get scraped into the RASC e-news post. Hrm.
This explains why, for a while now, I've been getting the odd non-member query...
heard it's out
shared cultures supported in Stellarium
That said, a key strength of Stellarium is that it was an open system so more starlore information on stars, constellations (with artwork), and planets could be added.
Then I dove into the app on the John Gomez computer.
Stellarium 0.21.0 has starlore or sky culture information for:
- Al-Sufi
- Almagest
- Anutan
- Arabic Moon Stations
- Aztec
- Babylonian (MUL.APIN and Seleucid)
- Belarusian
- Boorong
- Chinese (traditional, contemporary, medieval)
- Dakota/Lakota/Nakota
- Egyptian
- Hawaiian Starlines
- Indian Vedic
- Inuit
- Japanese Moon Stations
- Kamilaroi/Euahlayi
- Korean
- Lokono
- Macedonian
- Maori
- Maya
- Mongolian
- Navajo
- Norse
- Northern Andes
- Ojibwe
- Romanian
- Sami
- Sardinian
- Siberian
- Tongan
- Kukano
- Tupi-Guarani
- Vanuatu (Netware)
- Western (Roman-Greco, H.A.Rey, O.Hlad, Sky & Telescope)
She was suitably impressed. Might even download the software. SkySafari has nothing like this.
And Stellarium can operate in many different languages.

made lists for the FNGC
He correctly noted there was no list. Just a long (115 pages) PDF document with form pages with space for log notes, sketches, etc. He felt a straight list would be far more user-friendly in the field.
Indeed. In the same manner as the new Double Stars program, I have been thinking the others should have lists in useful formats. In fact, I think we should provide electronic formats for the popular software apps that can show observing lists.
I made a proper list in SkyTools 3. Done.
I copied this information to an Excel file and converted it to a table to support filtering and sorting.
I duplicated this information, recomposed it slightly, to make a nice printed format, which I at last saved in Portable Document Format.
Uploaded the files.
I will use Chris V's Stellarium files once finished.
Updated the Obs Comm team asking for help on the SkySafari file. Dave C offered to help on that.

three weeks out
caught penultimate RASC show
watched the partial occultation (Bradford)
Tried the entrance from Noble Drive but the gate to the water tower was closed (and presumably locked). Headed to the school—St Teresa Of Calcutta Catholic—and parked near the jungle gym.
Ugh. Four (no five) trips up the steep grade of the reservoir. Don't have a heart attack, don't have a heart attack, don't have a heart attack. I was warm at the end of it all but the breeze was refreshing. A slog.
Rested for a moment.
Then began the assembly. Priority: the big telescope.
Put the make-shift windsock over the recorder microphone.
4:28. Set up the DSLR camera. Took test shots for focus and framing. Had the kit lens set to manual mode. Used a distant red blinkie light to get the focus.
4:38. Birds a'chirping. Started the Sony audio recorder. Oh oh, the battery level was low.
The ETX-90 was on the large metal tripod—on Jupiter. The C8 with supercharged Vixen SP mount powered with the SLA marine battery—on Saturn. Filters and other solar paraphernalia ready to go. Low cloud on the horizon, up to about 5 degrees. Hopefully that would not interfere significantly. Actually maybe it would make the view pretty dramatic.
All four moons were Jupiter visible.
Snapped a shot of the setup.
motorola e6, f/2.0, 1/15th second, ISO 2344, auto-flash, minor adjustments in DPP.
4:43. Put new AAA batteries in the recorder. Left it late and couldn't find the black-yellow rechargeables... Fortunately I had a some alkalines in astronomy case α (alpha) primus. Whew. Double-checked the time on the smartphone.
4:45. Colourful sky. Thick cloud bank...
Canon 40D, 18-55 kit lens at 55, manually focused, f/5.6, ½ second, ISO 400, daylight, RAW, minor adjustments in DPP.
4:49. Looked again at the ringed planet. I had noted this before. Faint moon, about 1.5 planet-widths distant, toward the 2 o'clock position. Two bright moons (or stars?) formed an equilateral triangle. Three to four ring-widths away. 9 and 7 positions. Very nice view. It's gonna be good this summer!
[ed: From SkyTools 4 Visual Pro, Tethys and Rhea were both at the 2 o'clock (east), very close together; Titan was at the 7 (west), and star HD 200183 was at 9.]
Also snapped the scene with the smartphone.
motorola e6, f/2.0, 1/15th second, ISO 1456, minor adjustments in DPP.
4:53. Listened to the animals and birds. Heard the town waking up...
The sky was turning a lovely orange-red. Put the jacket back on.
They were clearly working on the water tower. Lots of vehicles, temp. structures. Safety fence.
I wondered about street location to the west—Mills Court. Looked like less elevation changes. But it felt less secure. Too bad the wagon has a flat tire... need to fix that.
Breezey. No dew. Removed the lens cap from the camera to reduce shake.
5:02. Here they come! The mozzies found me. Put on bug repellent.
GO train arrived in town. The 522.
Hints of a pillar.
Canon 40D, 18-55 kit lens at 55, manually focused, f/5.6, 1/10th second, ISO 400, daylight, RAW, minor adjustments in DPP.
Had the Oregon portable weather station on the TV table. Relative humidity was 59%, air pressure was dropping, calling for rain tomorrow, 15.9° Celsius.
In the binoculars, I saw water. Reminded me of Rhonda's remarks during the comet session last July... [ed: Bottom of Cook's Bay. Georgina is over there somewhere...]
5:09. I spotted a family walking along the path. Up early for The Eclipse Show.
Looked to the school. No sign. Texted Rhonda.
5:15. She said she was on her way.
Some more people wandered into the park. One man asked if the clouds were going to cause a problem. I didn't think so. Weird to talk to strangers...
I manually slewed the C8 to toward the NE. It didn't like the positioning, the hand controller thought it aimed below the horizon. So I rebooted the mount and forced it into sidereal tracking mode.
Sky was turning orange.
5:20. The Sun pillar was taller now.
Canon 40D, 18-55 kit lens at 55, manually focused, f/5.6, 1/50th second, ISO 400, daylight, RAW, minor adjustments in DPP.
5:24. Rhonda arrived. She noted it was clear. Impressed with my setup. She asked if I had eclipse glasses. Yep, various types, and the cards. She was curious how many trips it had taken me. "You got some cardio in." Tucker was confused! Ha ha. Showed her the Lake Simcoe. Oriented her to the setup, white filter on the C8, orange filter on the ETX. There should be some sunspots visible in the big 'scope.
A women arrived the park. "Love your setup." I thanked her. Too bad I couldn't let people have a look.
Rhonda asked about the path of the eclipse, the best place in the world. Nunavut would be good.
Oh. Oh, there it is. "Look at that!" Rhonda saw it.
Very cool. Two spikes pointing upwards.
The kids saw it.
5:37. Sunrise! Two spikes. Unfortunately, the camera could cope.
Canon 40D, 18-55 kit lens at 55, manually focused, f/5.6, 1/125th second, ISO 400, daylight, RAW, minor adjustments in DPP.
Nothing was visible in the eclipse glasses. Indeed, already heavily filtered by the atmosphere.
Rhonda asked for the spatula was for. Fun tiny Sun images.
Rhonda asked how long the event would last. About an hour.
5:41. Oh oh. Blocked by the clouds.
Canon 40D, 18-55 kit lens at 55, manually focused, f/5.6, 1/200th second, ISO 400, daylight, RAW, minor adjustments in DPP.
"That's great," Rhonda said. "Here we go."
I thought it good.
It was getting hard to look at...
5:42. Knife edge!
Canon 40D, 18-55 kit lens at 55, manually focused, f/5.6, 1/200th second, ISO 400, daylight, RAW, minor adjustments in DPP.
In post, zoomed in to reveal the thin arc of sunlight.
Cropped and sharpened in DDP.
The DSLR was overwhelmed as the Sun cleared the clouds... Kicked myself for not making a solar filter for the camera...
Rhonda called me over to the C8 with Kendrick solar filter. It was very nice with the 36mm wide field eyepiece.
Almost cleared the cloud.
She could see it in her glasses, at last.
I couldn't see any sunspots. Regardless, it was amazing.
Rhonda observed that you couldn't see anything with the unfiltered eye. It was just a blob.
Rhonda didn't see anything in the Meade. I suspected it had drifted away.
5:50. Yes! Got them with the solar eclipse card in front of the camera lens.
Canon 40D, 18-55 kit lens at 55, manually focused, f/5.6, 1/4th second, ISO 100, daylight, RAW, minor adjustments in DPP.
Rhonda suggested photos through the C8. I could. But we'd lose the nice view.
I tried aiming the ETX. Did some tricks and got it aligned! But it was very faint... the dark filter and the small aperture. And low. Rhonda couldn't see it. Her after-image spots were distracting.
Told Rhonda about Katrina's remarks from 2017. "Moon's in front of the Sun, man!"
We tried the spatula and colander. The strainer was better, a couple dozen little crescents.
I showed her my super-duper eclipse viewer thingee with welder's glass. She really liked the view! Good optical quality I guess. Rhonda offered it to the family. They enjoyed that.
I had a look at Photo Pills.
6:03. I tried an afocal smartphone shot.
motorola e6, f/2.0, 1/30th second, ISO 144, minor adjustments in DPP.
Another shot of the gear, in full sunlight now.
motorola e6, f/2.0, 1/60th second, ISO 59, HDR, minor adjustments in DPP.
Rhonda asked if I had RASC stuff, for the family, interested in astronomy. I thought I might. I found some business cards in the astro case. She was doing the promo!
She said "they loved that."
Mounted up the 40D to the SCT.
Big. I wasn't expecting that. Did not think to bring the focal reducer... Another little goof-up in my planning.
6:11. The Moon was moving away. Less than 50% coverage now.
Canon 40D, C8, Vixen Super Polaris with GoToStar tracking, manually focused, f/10, 1/10th second, ISO 100, daylight, RAW, adjustments in DPP and Photoshop.
[ed: Two sunspot groups were visible. Near the right, AR 2829, with two spots. Didn't notice it at first but got AR 2832 with 4 spots!]
It was quiet on the hill. Everyone else had left.
6:17. Oh. Sundog! A prismatic sundog showed to the right of the Sun. I pointed it out to Rhonda. Took a moment but she saw it.
Invited her to try the view in the Meade again. It was brighter. Tricky though with the small aperture mask and the 26mm Plössl.
Rhonda offered to bring the car around to the tower base. It'd be easier to pack up. She scouted things out.
I switched back to visual in the Celestron.
She found the gate open! Good. She moved Ruby.
6:26. Another afocal shot.
motorola e6, f/2.0, 1/200th second, ISO 50, minor adjustments in DPP.
Very difficult to identify sunspots from dirt and dust!
6:26. Spotted some spots. Opposite the Moon. Definitely there [ed: that was AR 2829]. Visible despite the bad seeing.
Started to pack up. Birds were quiet, the cars were loud, and the cops were busy.
6:31. Checked the conditions. Now: 52%, 16.4°.
Continued the teardown. C8 last...
I spotted Rhonda near the tower. "Quick, quick." She saw the sunspots. Offered the view of Fourth Contact to Rhonda. "It's a big deal. Soak it all in." She was surprised how rapidly it changed.
I thought the Sun looked like a round object with an edge sanded flat.
We quickly swapped views to the finish.
The Moon was clear of the Sun.
6:42. The End. We did it! "Wow," she said.
Rhonda graciously hauled stuff to the car as I tore down.
The car sank under the weight off all the stuff.
Back home. Rhonda was feeling a bit off so we had to forego the celebratory breakfast.

more deck viewing (Bradford)
spotted spots (Bradford)
Fluff floating and yellow butterflies flitting.
Noted a large sunspot at the 9:30 o'clock position (west), near the edge of the disc.
Also tagged two spots, actually, a complex region, at the 8:00 o'clock position, a bit further in.
Used, at last, the Meade ETX 90 with a custom off-axis solar filter made with one lens of an Eclipse Megamovie Berkeley solar glasses.
Optically superior to the U of T glasses. Also, it cast a nice orange tint.
§
Had a devil of a time.
I had built the off-axis mask yesterday and simply could not see the Sun. Gave up when clouds rolled in and a (er, another) trip to NoFrills called.
Tried again this morning and encountered the same problems!
Started to wonder if it was a scale issue... but that didn't make sense. With SkyTools 3 Pro, I verified it would fit easily in the field of view with the Celestron 26mm ocular (at 48 times magnification). Yeah, as I suspected, it should be no problem.
North is up. East is right.
Grabbed the Kendrick full aperture solar filter for the C8 'scope and mounted it on a tripod with work clamps. Ensured it wouldn't fall off. It was not windy so there was little danger from a gust. Placed it in front of the main OTA and finder scope. Then I was able to use the finder to bull's eye the disc. OK. On the cross-hairs.
Yes! In the eyepiece. Indeed, it fit nicely.
Great view, actually. The Kendrick film is awesome. Bright image but then, full aperture.
Went to the custom filter, carefully installing it to not move the 'scope.
Saw the Sun! But it was soft. Very soft. And dark. Unfortunately, the film in the U of T 2014 eclipse glasses is optically poor.
Looked at my remaining supplies and considered chopping up one of the orange, optically-good glasses when I suddenly realised I could make a non-invasive mask!
Back.
Shot with the motorola e6.
Much better view in the custom mask with the new filter.

According to Spaceweather.com, the large spot was Active Region (AR) 2827. The dual spot complex was not identified...
Screen grab from Spaceweather.
North is up. East is left.
Oh ho. Missed it while zooming in on the large scale image. The dual spot region is new and has not yet been labelled.
I did not see the spot AR 2829 near the middle...

The heat must have loosened things up! I found the Meade ETX optical tube assembly rotating. I tightened it up in the base. Odd. That also affected focus!

So, after a lot of fiddling and experimenting, I have a working solar filter for the little Meade. I will add this to the arsenal of tools for the 10 June solar eclipse.

Orion bought Meade
I had seen remarks in a groups.io groups about Orion buying Meade a couple of days back...
Spotted this article at Sky & Telescope.
Optronic Technologies, Inc., aka Orion Telescopes & Binoculars, announced the acquisition of Meade Instruments following the approval of the United States Bankruptcy Court for the Central District of California.
got s-biners, will tent
The Omuky S-shaped carabiners are just what I've been looking for, for the observing tent. They are large, 8.8x4.0cm. The pack included 7 pieces.
