will help on Monday
Asked Randy if he could help me review the Survey Monkey evals from the spring telescope clinic. He quickly replied. Happy to assist. But wouldn't be able to do so until the 5th. OK.
observing from Peter's yard (Etobicoke)
Headed to Peter's to drop off the repaired Dobsonian. Found him in the front yard with his little Newtonian looking at the gibbous prismatic Moon through thin frigid clouds. 26mm with a doubler. I aimed to the rich area near Clavius.
After I showed him the focuser repair, we noted holes in the clouds. We briefly spotted the Pleiades (Messier 45 or M45) straight overhead in a pocket.
We caught up. I shared that it looked like I'd be inheriting a classic 6" Newt soon. He sought advice on his Orion parallelogram.
Back outside, despite the cold, we did a bit of observing. The south-east had opened up. Peter loaned me a 31mm Nagler.
Took in the Moon after trying to adjust the finder scope. Weird lighting in Copernicus. Does it have multiple centre peaks?
Then I put the 8" on Sirius. While low, it looked OK. Some faint stars nearby. I was happy with the collimation. I could easily focus. I did not notice image shift. Huh.
From the street, Peter spotted Jupiter. I moved the loaner Dob and bulls-eyed the beige dot over the neighbour's house. Four moons. Two stars perpendicular. I knelt on the ground. The cloud bands appeared. A nice view. Later it swam in the heat waves.
Wow. First observing in a long time.

found an ALAMP project
I noticed a new ALAMP test site today. Anglesey Blvd at Royal York Rd. That's just north of Dundas St W. Went by in the daylight so no lights on. But I noted the cut-off heads and flat lens on the bottom. And antennae sticking out. Shared this on the RASC Toronto Centre Yahoo!Groups.
Peter was surprised as he thought the ALAMP project was dead or on hold.
Joe drove by and looked closer. Toronto Hydro changed all the shades to full cut-off. He found the lamp lens was absolutely clear. He noted the new fixtures put out a lot more light but the circle was tighter. The walls of the nearby apartment buildings were not lit. Curiously, he found they were definitely not LED.
He then tried to confirm his observations by visiting the "posted" website on that project sign - http://www.torontohydro.com/ALAMP - but the webpage was dead!

shimmed the focuser
I didn't like the action. The focuser was jamming after drawn all the way out. The little cuts in the top of the draw tube.
I backed out the tiny set screws. One was flopping around—clearly stressed from previous abuses. I wondered if a shim or sled had gone missing...
Added plastic shims to the "top" of the focuser casing. This greatly reduced the flop!
Ha! The shim material was "donated" by the old astronomy case α! The drawing action was smooth! Yes!
Very happy.

What a cheap, backward design. More pressure on the worm gear pushed the draw tube up and away from the plastic shims...

On a somber note, the interview of Chris Hadfield was written late October 2013. And he predicted an unpleasant outcome with the privatisation of space. "Eventually they'll crash one." Curious, reading this now, after the incident of October 2014.

gifts 2014
Received a number of astronomy-related gifts this year from the family.
Darth Vader's head. In chocolate. From Regal Candy, who appears to make Pez. And Rockets! I find your lack of body disturbing. A fleece blanket with stars and planets. Shall I take that to the observatory? Or keep it in the camping gear? Index cards, 50, and a case, with a space theme. Except I'm trying to not use paper... Huh. I did have an unused set of index cards in astronomy box α... A hand-made knitted item from sis. Mom didn't recognise it. Steve, while she was making it, thought it weird bug. I recognised it right away. "Don't ride in anything with a Capissen 38 engine, they fall right out of the sky." A medium-sized button. Of a full Moon! Oh dear.
A magazine.
The October 2014 issue of Canadian Geographic with a feature article Canada in Space. Interesting...
A special issue by National Geographic entitled The New Universe. This might be mostly a review for me... It's all changing pretty fast!
A binder. Part of the National Geographic Space series. Featuring the Great Orion Nebula.
Tried to think of a way I might be able to use this... Some RASC paperwork? General astronomy paperwork?
The coolest item? Chris Hadfield's book You Are Here.
Looking forward to examining closely his wonderful photographs from on orbit.
Thanks sis, Steve, and Mom!

lost in stars
Some new members posted a note on the RASC Toronto Centre Yahoo!Group. They shared that they had recently looked skyward and on seeing stars grabbed the binoculars and tried to find their way. "WE HAD NO IDEA what we were looking at, looking for or even which way to face."
I kicked off the discussion. I encouraged them to get a Star Finder or planisphere.

picked up canvases
John called. Said he was almost done. I could pick up on half an hour. I drove downtown and parked out behind the shop. He was wrapped the prints as I arrived. He opened up the wrap to let me look. The igloo. It was dark. Darker than I had hoped. Oh well. Nothing to be done now.
And no frame. I thought I was getting a frame. Around the outside... Damn. More issues. Was I mistaken? I didn't know. Too late now.
I paid and left. Salvaged. At least I would not be emptied-handed to me family on Christmas day.

out of options
Emailed John at Exposures after not hearing anything all day. I was dreading the outcome. No problems delaying his completion. The canvas prints would not be ready and I had locked into to leaving Sunday morning. These major Christmas gifts to my family would not be ready. What would I do? What would I give them instead. What could I possibly given them?
I was very disappointed.
The worst part of it was, I didn't know what was going on. I didn't think that appropriate. John should have asked his staff to give me updates. At least I'd know that some progress was being made.

found glue
Took apart the focuser. It was like maple syrup!
The old grease had turned to goop. It was making the focuser very stiff.
There were also notches or cuts in the top side of the draw tube... Would need to figure out what to do about that...

Read an article about astronaut Kelly and cosmonaut Kornienko planning for their one year stint in space. This will be really interesting.
I still think it fascinating that NASA has Scott's twin brother Mark Kelly. Their launch is coming up soon, if I understand correctly, March 2015...

busy time without a plan
Allard relayed a message received via the web site. Another telescope donation request. I don't recall any discussion about my ideas around a new "intake" committee. Receiving this note now, at this time of year, I suspect will mean it will not (despite Allard's wishes) get dealt with in a timely fashion.
problems at the print shop
Still no email. Phoned Exposures. Got John on the phone. I was quite civil. Asked what was up. John said the first print run did not go as planned. A problem with "banding." And then he had consumed all his canvas supply. He hoped to finish later in the day. But there was the issue of dry-time. Wouldn't be ready for pick-up until tomorrow. "Saturday," I asked? He apologised. I said I wanted him to keep me updated.
This scuttled the morning departure.

Still no response. Sent an email message to John at Exposures. Asked if I'd be able to pick up my canvas prints.
I did not expect any delays. He knew my timelines. I think he knew this was for Christmas gifts. Maybe he's not good at estimating. Maybe some factors are out of his hands.
Still, I think communicating what's happening would be good...

more organics detected
NASA confirmed the discovery of organics on Mars based on materials drilled by the Curiosity rover. This in addition to the methane detections from before. I read the article on the Discovery web site. Explaining both the organics and the methane will require far more analysis and likely not be answered with the current instruments. All that said, microscopic life would have a tough go, today, on the red planet. Still, it is encouraging to see markers, hints, tells of the possible building blocks of life.
not a peep
No call. No email. I had expected John to phone me to say the canvas prints were ready.
I was not happy. Not fun now.
At one point I had entertained taking the Friday afternoon off (I still had a half-day time in lieu). But with everything else going on, I decided to carry on. That meant the prints pick-up could slide to Friday.

I provided more evidence to support my argument that F was meant instead of T. To add some weight to Michel's hesitant note. The listed magnitudes for the Σ2991 are 6.0 and 10.0. Struve 680 Tau, with the same mag values, Michel listed as F.

acquired hardware
My half-day time-off in lieu I used to go downtown. To get various errands done. One objective was to obtain fasteners for the barn door tracker project. To augment the parts from Ian's kit. I was very pleased to procure a long 3/8-16 bolt, for the ball head, along with some washers, some teenie, short #4 bolts and nuts (unfortunately I couldn't find matching washers so I took some #6 instead), some small #4 self-tapping screws, and some unusually-sized female blade connectors (in the auto department). The latter I was really surprised by.

Visited Exposures. Right where I thought it was. The woman at the desk called John. He invited me up to the studio. Transferred my two images to John's computer. Loaded into Photoshop. We had to fiddle with the igloo image given the way I had framed it and that "good" borders, for a canvas, were typically taken out of the image. The Ring Nebula was not an issue in that respect—lots to work with. Some colour and contrast corrections and we felt we were good to go. I could pick up on Thursday afternoon. John said he'd call me when ready.

project box completed
Made more progress on the barn door tracker.
Yesterday, after work, visited The Gorilla. Active on Queen. Headed straight to the far aisles. Found some nice single pole switches. I chose another one with a red switch, a bit larger this time, and with I/O markings. Oooh. Noticed aircraft switch covers, in different colours! A future project perhaps... Stumbled across the female CLA box so I grabbed one of those. For a future 12 volt cord extension... Then headed to the wire section. Picked up 2 metres of microphone wire. For the barn door motor.
After the noise-ban was lifted, I started work.
Soldered up about half the length of the mic wire between the motor and the RCA plug. Tested. Works!
Borrowed Will's hacksaw to cut down the debugged PCB to fit in the project box base. Drilled the four holes to mount to the case. But did not yet have the mounting screws...
Made all the openings for the controls in the clear cover of the project box. Mounted the controls. I will need some very short bolts for the N-S switch and RCA jack...
Wandering drill bits aside, I was very happy.
All I needed was screws for mounting the PCB and a few more very small bolts for the switches...

John replied again, quickly. Fantastic! Getting logistics sorted out before next week!
He explained that the proper way to frame a canvas was to have it put on stretcher bars. He quoted me on that. And then he said he should go into a frame (e.g. gallery style black frame). Again, he quoted me on that.
The best news was when he said, "Yes, we can have them by the end of the week if we order by Tuesday."
He encouraged me to visit and spend some time going over my photos.

tried Clear Outside
Byron found a new clear sky prediction tool. He shared the link, pre-programmed for Toronto, on the RASC Toronto Centre Yahoo!Group last night.
I took a look. Neat! A 7-day, hourly cloud and weather forecast tool. Designed by astronomers for astronomers. Takes into account low, medium, and high clouds, wind speed and direction, temperature, humidity, dew point. And air pressure! I immediately adjusted it to be centred on midnight (that's like SkyTools). Oh cool! It shows ISS flyovers!
The beta product is provided by First Light Optics in the UK. I think I'll add it to my weather portal pages...

quick and dirty TSTM
Feeling badly for not delivering The Sky This Month, I issued a quick
bulletin on the RASC Toronto Centre Yahoo!Group... I had already done a
bunch of the research.
Hi,It's better than bad; it's good.
Due to a work conflict I could not attend the RASC meeting and deliver my The Sky This Month presentation.
Regardless, I wanted to share a list of upcoming events. Enjoy.
* Geminid meteor shower. Active until Dec 17. Peak this weekend! Can produce up to 120 meteors per hour! That's a higher rating than the Perseids. Associated with the Palladian asteroid.
* Quadrantid meteor shower. Active from Dec 28 - Jan 12, peaking on Jan 4. Up to 120/hr! Another good event! Moon should cooperate. Appear to radiate from a point between northern Boötes and the handle of the Big Dipper.
* Globe at Night. Measure sky brightness and submit your results. Runs until Dec 20. The January campaign starts Sun 11 Jan. http://www.globeatnight.org/
* Visible evening passes or flyovers of the International Space Station continue until Mon 29 Dec with a couple of bright ones on tap. Morning passes start 5 Jan. http://heavens-above.com/
* 3rd quarter Moon. Sun 14 Dec.

learned about mounting and the wrap
Elaine and I chatted by SMS. I asked her about her canvas prints, how they were mounted. She told me about the border for the wrap.

asked for a quote
After checking the web site for a price list, I sent an email to John at Exposures on Wellesley. Said I was referred by Elaine and Tony. Inquired about getting some astrophotography images printed up, around the 11x14 size, ideally onto canvas. Asked for some approx. prices.

asked for advice
Put a message to the RASC Toronto Centre Yahoo!Group looking for advice on a print shop who could do nice work with astrophotography enlargements. Received a great number of responses! But it was Elaine's that intrigued me... For I had seen the results.

water debate heats up
Read the article on the European Space Agency web site about Rosetta's surprising discoveries and how it's cometary water vapour analyses show it to be quite different than Earth's oceans. This seems to be stirring the pot about the origin of water on our planet.
I think I need to read more about this. Can you do an apples-to-apples comparison? Would some variance not occur given time-frames and interactions? That is to say, the water on our planet has been, um, recycled a few times now. It is a vexing question. We're 2/3rds covered with salty water. Where did it all come from?

debugged the circuit
Had another go after the disheartening results Sunday.
7:37 PM. Tried to sort the motor direction issue. Tested the barn door tracker control circuit without the harness. It worked. Manually switched connections on the output of the board, clockwise then counter-clockwise. It worked. That was really good news for I felt that was the trickiest part of the circuit.
But still there was no motor light. The red LED was not illuminating as the motor turned. I directly tested the LED. It worked. I must have misread it and installed it backwards. Did further debugging of the LED. Finally decided to install a new one.
With the harness, things were still not working correctly. Did more reverse checks. And at long last I found it! An interconnection to an isolated circuit! There was no circuit between pins 4 and 14... I made a new circuit and tested. Not working! Sheesh.
Wait. I did more checks from a different direction... Checked the PCB and discovered the purple wire had fallen out. That's not exactly the right way to say it. It wasn't connected. It looked like, somehow, it had desoldered. Not sure how that could happen...
9:08. Connected everything up, including the harness. Everything worked! w00t! What a relief.
Upshot of all this...
My schematic diagram was perfect. My printed circuit board diagram was perfect. I made one mistake while soldering. I was still not exactly sure what had happened with the LED... No matter. I was good.

traced the board
Started tracing. Tried to find the fault. Immediately I found the power switch was not working! What?! Or at least the pole I used didn't work. Shorted the switch. No LED. Damn. Wait... a sound. The motor! The motor was turning, clockwise, in fact. Holy cow. It did work. Dialled the speed up and down. Yes. The barn door tracker control circuit was working... partly. Tried the N-S switch—stopped. OK, I was not out of the woods yet but I was very happy with my progress. It was not a catastrophic fault. Perhaps a simple matter on one side of the hemispheric circuit...
§
Other continuity tests, further downstream yielded peculiar results. I must have a short, I thought...
Then I found a dead resistor. Yes, a dead resistor. The 470 ohm for the LED. No continuity! How the heck does a resistor fail? Readied to swap it out.
I was discouraged. I decided to sleep on it...

PCB didn't work
First attempt. No joy. Gah. My first try at the barn door tracking control unit, with the improved layout, did not work. Always a risk, wiring up a custom breadboard...

decided on new layout
Now that I had all the circuit board parts, I started working positioning, considering layout and interference.
Settled on the new layout for the barn door tracker control unit.
Ready to solder.
§
Not sure why this happened, if it was intentional or a mistake, but the 150 ohm ½ watt resistor was replaced with a 100 ohm...

tuned motors and worms
After reinstalling the motor, performed tests. All OK. Adjusted tension on motor gears. Adjusted worm gears. Feels really good. The NEQ6 is essentially ready to go.

New Horizons awoke
Watched the New Horizons probe wake up. Gettin' real... Pluto research will be happening soon now.
clarified deadlines
Tried to get some clarity on the Journal submission deadlines. I thought I had met one and the next was accelerated. Jay apologised for any misunderstanding and included a schedule. For 2014 mind you; but next year's dates should be similar. I entered reminders into my agenda.
Surprise: Jay and James accepted my proposal to publish the deadline within each issue.
A side benefit is that I can ease-up on the current article!

happy for Nicole
Another aspect of the Orion launch that was rather exciting was that my friend Nicole Mortillaro was in Florida, on assignment, for Global News. As much as possible I followed her blog and Facebook posts. I was very proud of her. Her first launch. And I wouldn't wish it on anyone but I'm glad she experienced the scrub too.

let bed go
After a friend posted a bed frame for sale on Facebook, I consulted with the CAO crew. But we decided it was too far to pick up and that we had no were to store it in the interim. We let it go.

discovered a conflict
I suddenly discovered a conflict. For a long time, I was on the docket to deliver The Sky This Month at the December RASC Toronto Centre Recreational Astronomy Night Meeting. But work had scheduled me to deliver training courses to the Asia-Pacific clients—in the evening in this time zone! Damn! I let Markov know in the hopes we could find another presenter...
phone fixed
Bell Canada repaired a bad wire between the CAO junction box at the foot of the drive and the other side of the road. Yeh.

let's be clear
Read the letter-to-the-editor by Karen Mortfield posted to the York Region Metroland Media Richmond Hill Liberal. It made it very clear—I think—that the Royal Astronomical Society of Canada - Toronto Centre has been effectively and successfully (and correctly) operating the David Dunlap Observatory for over 5 years now, serving over 20 000 visitors. It also addressed the issue that another group is trying to make it seem like they have done a lot to maintain the facility and will, in the future, be conducting public outreach when in fact they have done nothing. And will not.
The RASC runs the DDO.

he haggled
Phil scored the case for me from the Markham. At a great price. Wow. He inspected it too.
Said it looked very good. Lots of storage space. Although, he didn't think it would take full sheets of paper. Or books. Can't wait!

Learned of a case supplier in Markham, not far from Phil's work. Looked like a good option for replace astronomy case α. Asked if he could help me out.

is there a budget?
Asked Stu if there was a budget for the RASC loaner Dobsonian telescope repair.
I found low-end new focusers for $100. At least it uses bearings!
And good ones for $200. Dual speed!
A new 8" Dob, fixed-tube, is probably a few hundred dollars new...

Funny timing, having recently received the Nov-Dec issue, now I had the Jan-Feb issue to absorb.
Looking forward to the highlights for the new year...
