too long
Was hoping to finish the barn door tracker today having recently cut the wood plates. I also wanted to install the finder scope I had picked up while at Mom's. But the hinge screws are too long! Man... Another delay.

fixed power cord
Fixed Tony's power cord for his Sky-Watcher EQ3 mount. The wires had frayed and shorted right near the strain relief of the CLA plug. I took it apart to figure out the polarity. Printing on the shell; bumpy wire to the centre.
The 7-ampere fuse was blown. Put a 5A in from my parts bin. Tested on my power tank. Red LED. Good to go.

cut wood
Mr dos Santos let me use his jig saw. I quickly cut the Baltic birch plywood as per Gary Seronik's barn door tracker diagram. I decided to keep the bottom plate simple—I don't think I'll bother with the circular element.
Huh. Seem small, the plates. That's a good thing, I suppose. Less weight.
Let the assembly begin!

Jovian exhibition (Mississauga)
Very fun evening.
4:30 PM, Fri 23 Jan 2015. Cut out of work. The lads wanted me to join them for a end-of-week debrief. Just one drink. Nope! I'm on a mission. Sorry. Have fun!
5:52 PM. I was very surprised to secure a local AutoShare ride. Not the closest, but still.
7:18. Arrived the dos Santos kitchen.
Almost immediately, I fired up SkyTools and started configuring telescopes. I added Tony's SCT, Elaine's big refractor, and finally the little refractor. Add camera details, finally, after scouring the web, and Yahoo!Groups, for specs.
Phoned the CAO. Gave a number where I could be reached, if they had any trouble.
Elaine reviewed the webcam operation and quickly demo'ed the software installed on Tony's laptop.
After a fantastic dinner by Tony and wonderful dessert by Elaine, we headed out back. He let me loose.
First order of business was dew preventing. I pointed out all the frost to Tony. He fetched the DSLR lens cap while I installed the dew cap on the SCT.
I aligned the Celestron CGEM 11's finderscope and Telrad, using the Moon. Used an eyepiece to centre on targets. Tony and I connected the USB Chameleon colour camera (CMLN-13S2C-CS) and started to play with the FlyCapture camera software. First exposure to this app. Adjusted the brightness and related settings. Set up a new folder. Verified there was lots of hard disk space.
The software was displaying the recording dialog but after setting it the first time, it was not letting me change it. After rebooting the Dell, I got the recording to work and played back the video test files to verify. 1200 frames per run. AVI video format. Mild drifting but it was OK. Seeing looked really good.
Tony spotted my 2" mirror diagonal and asked if he could use it. He put it on the TEC 150.
The seeing was quite good. The cloud bands were mottled with ragged edges.
9:44. Took a break. I participated in an e-vote, followed-up with new president (who seems unwilling to drive south), agreed to a new (sorta) committee member to the CAO, and asked a question about a CAO group event.
10:35. We spotted Callisto's shadow. Very nice. Down the middle, very nearly on the equator.
11:39. I spotted, in the wonderful TEC view, the little bite of Io's shadow appearing. It took a moment for Tony to see it.
Io's shadow also near the equator.
11:56. Watched Io merge into the planet's disc, then become a tiny bump, then disappear. Very good seeing.
12:11 AM, Sat 24 Jan 2015. During a warm-up break, messaged Katrina. Told her I too wanted to get to the CAO. Craving dark skies.
12:45 AM. It was super-cool watching Io's small fast-moving shadow merge into Callisto's. That was a first!
1:26 AM. The main event was coming up. Callisto merged into the planet. Clouds were holding off.
1:31 AM. Europa's shadow appeared. Woo hoo! Three shadows. Another first!
Europa's shadow was not in-line with the others. It was touching or very near the south equatorial belt.
It was fascinating seeing Callisto "parallel" to the shadow, looking like another shadow itself. It was in the north equatorial belt. Yet another first.
And then the clouds rolled in. What incredible luck. What incredible timing. We packed up, covered the gear.
Inside, I tried to figure out the AVI files. I could not seem to figure out what was going on. Registax 6 would not open, or at least display the frames, in some of the AVI files (the big ones, unfortunately, with most of the frames). That was a little disappointing. Tony really wanted to post something...
When they said it was 4 AM, I almost jumped. No wonder I was having so much trouble. We crashed.

We got them! The three shadows on Jupiter. Tony and I were very happy. Cheers!
The faint dot top-left of the planet is the moon Europa. The shadows, left to right, are Europa's, Callisto's, and Io's. Callisto is above Europa's shadow. Also, Io is just barely visible to the right of Callisto's shadow!

Metal case recently arrived from Amazon. Not in good shape.
Scuffs at various places, some through the paint down to the metal. Paint chips near the front corner. Deformation in the metal at the side near the back.
It works. I won't send it back. It works. It will surely get abused more as I use it.

Bumped into Ian in the DDO parking lot. He had forgotten his coffee in the truck.
He grabbed the Baltic birch plywood for me. Oh. Big piece! Lots of extra if I goof up.
I decided to take it inside to have a good look. Beautiful.
Now I can work on the largest single elements of the barn door tracker... And mount all the hardware.

investigated M40
Did some research for Sue. She asked, "Is there a reasonably accurate measurement of the distance in light years between the 'double stars' in M40?"
I found notes at wikipedia on Messier 40 (M40): In 1991 the separation between the components was measured at 51.7", an increase since Messier's time. Data gathered by astronomers Brian Skiff (2001) and Richard Nugent (2002) strongly suggested that M40 is merely an optical double star rather than a physically connected system.
I found other interesting details on SEDS: The position angle has also changed since first report in 1863.
The Lick Observatory Index Catalog lists the spectrum of the primary as G0, while SIMBAD lists them as A (HD 238107), spectrum G0 and B (HD 238108), spectrum F8. Skiff gives their spectra as K0III and G0V (Skiff 2001).
If the primary is a main sequence star, then Skiff said the distance was approx. 300 light years.
In 1998, Feltz evaluated the Hipparcos data to yield a distance of 510 light years.
Nugent in 2002 reevaluated the spectral types provided by Skiff to derive spectroscopic distances of 1900 +/- 750 and 550 +/- 230 light-years, respectively.
He published this, in fact, Journal of the Royal Astronomical Society of Canada, Vol. 96, p.63, in 04/2002. Huh!

checked Diadem
Tried to answer Sally-Anne's questions in her comment on my alpha Com article.
Q: Is it possible that the exact dates of periastron can be known?
A: Yes, I believe so. SkyTools 3 Professional shows that the orbit is "definitive." This suggests the orbital data is known with some confidence. I'm not an expert on these matters but I think there are 6 (?) parameters used to calculate an orbit, like eccentricity, argument of pericentre, etc.
Q: [Can periastron be determined] by counting forward from previous PA and comparing?
A: Yes, that should be quick and give a crude answer. But, again, if the orbit data are known, it should be possible to compute with some accuracy. According to the SkyTools Stellar Orbital Companion motion trails plot, the next periastron should occur late 2025 or early 2026.
Q: Do [you] have an idea when in spring '15 it will occur?
A: I did a plot and it actually looks like the close approach happened in November or December of 2014. And now, the B star, is moving to the north.
Q: "U said but rt now AB are separate... i guess that is to be expected since it's winter, or shd they not need to have so far to travel?"
A: I'm not sure I fully understand the question. In my 19 Jan 2014 post, I shared that the software predicted the stars to be 0.21 seconds-of-arc apart. This seems to correspond to the plot, i.e. about 1/3 of the maximum elongation. But they were moving closer. Now, a year later, they should be virtually on top of one another, so difficult or impossible to split. That is supported by the current report from SkyTools: "not splittable currently." In the summer of 2017, for two years, the stars should be far apart, almost at their maximum.
See the Journal of Double Star Observations for more information.

Another clear night. And I've no options. Considered, briefly, with the "dry" roads sparking up the car and heading north. But, I was too tired. And I needed to research the Carmanere region... Mars was easy to see. Too late for the inner planets. Orion rising, belt nearly vertical.
headed home
Chose not to go to the meeting tonight. I just can't deal with some of the personalities. Sorry. I don't need anger nor hostility. I'd much rather relax and have some quiet time. Could use the time to catch up on other overdue items.

Can't believe it. Captured Mercury in the point-n-shoot camera! Oddly, I could not see it naked eye (forgot my corrective lenses this morning).

helped Tony with Canon
Helped Tony shoot some astrophotographs with his new Canon EOS Rebel T5i DSLR.
Too closed in from the backyard. We went to the vacant lot. Horvatin Hill? Cool. Surprisingly dark.
We learned how to manually focus. Weird, the outer ring, turning easily and continuously... I noticed when defocused the shape was perfectly round. [ed: That's a feature: it has a "circular aperture" due to rounded diaphragm blades.] We turned off the Image Stabilisation as well.
Sorted the controls. Holding the Av button to step down the lens. ISO on the top surface right side. Changed the white balance to daylight, from incandescent. Set the image format via the Menu...
Interesting to see that the ISO could go to 12800. I encouraged him to explore the limits, check the noise, at that high level.
The fully articulated screen was nice.
Programmed his intervalometer. Exact same layout as mine. However the screen backlight was white and bright.
I look forward to his shots.
We easily spotted the comet, on the display.

grabbed comet data
8:30 PM. Finally forced myself to head out. Don't be lazy.
The backyard did not appear to be an option. Suddenly I decided to head to the school. Hopefully they'd have a decent sized yard that was reasonably dark.
Put on the long johns. Atop the undershirt and short sleeve shirt, I pulled on long sleeve shirt, the black hoodie, the Michigan sweater, and the red winter coat.
Packed the big tripod (with hex clamp), camera and kit lens, two spare batteries, intervalometer, the netbook, the camera-computer USB cable, a flashlight, and two plastic bags. Stuff the gear in the Targus bag. And out the airlock...
The school yard was not bad. Stupid wall pack lights everywhere. But in the baseball diamond, it was pretty dark to the south and south-east! Surprising.
Brilliant Jupiter to the east.
Did some test shots with the camera, stand-alone. Ugh. Orange sky.
Tried to focus with the back screen. Stopped down the lens. Couldn't leave my gloves off very long. The wind gusted every once in a while.
The thought occurred to me that I'd be ticked off if the focus was bad. So I connected the computer, aimed at Jupiter, switched to automatic, and started to—battery died—replaced the battery, nudged the focus, switched to manual, and then re-aimed toward Orion.
9:16. Finished the test shots. Programmed the EOS Utility "intervalometer" for 5 second delay and 20 shots. Took me a couple of test shots to remember that the interval needed the exposure time. With the camera shooting 10 seconds, I set to interval to 15.
Took in the huge Winter Football while waiting.
I could see Cursa at magnitude 2.8; but not σ Orionis at mag 3.8. Not a terribly dark sky... Mind you I was not full dark adapted.
9:24. Finished acquiring the light frames.
Started the darks run as I tore down the tripod. Continued as I walked back home!
9:30. Finished the darks run half-way along the school's front lawn.
9:35. Bagged the computer and camera on the front porch and headed inside. Face was cold.

two on the way home (Etobicoke)
Spotted Mars and Venus.
Venus I only caught on the down the street, between houses. Five degrees up!
Another clear night. Warmer... But I'm tired...

lined up (Etobicoke)
Spotted a row on the walk to work. Gibbous Moon on the left, faint Regulus in the middle, a bit higher up, and bright Jupiter on the right. I thought it interesting that it was a nearly straight horizontal line. Nearly equidistant.
Curious they were nearly horizontal for me. I wondered if the Moon was well below the ecliptic. Then I considered that Jupiter could be above too. Two effects at the same time. [ed: Confirmed!]
Suddenly, it occurred to me that Saturn should be up. I found the yellowy point nearly straight overhead. I thought that the ringed planet. [ed: Nope. Probably Arcturus. Saturn was off in the south-east.]

weightless again
Spotted Antigravity beer at the local LCBO, beside another Flying Monkeys product. I haven't seen that on the shelves for a long time. A fine light beer. Best I've ever had.
Noticed a new label, featuring an photo-realistic image of an astronaut's helmet. Immediately wondered if Cmdr Hadfield was the cause...

found Lovejoy (Etobicoke)
Found comet C/2014 Q2 (Lovejoy) in the binoculars atop the tripod from the front lawn.
With the help of SkyTools, I star hopped from Rigel, to Cursa, 66 and 68 Eridani, then ω. Next stop μ and ν Eri. Then over to Beid and Keid. Finally to ξ. While slowly sweeping I spotted the small fuzzy.
No obvious tail. Smaller than I had hoped, due to the city skyglow.
Briefly considered imaging it but I didn't want to do so from the front yard. I still didn't have access to the back... Then the side door security light went off. Ugh. The prospect of hauling out more gear and trying to focus in the frigid conditions was not attractive... -18°C. -28 with the wind chill. 245°K. Lost my mojo.
Good enough for now.

worked at Mars (Etobicoke)
Found Mars. Had to work at it.
Thought I saw Venus as I left the subway station. Not 100% sure.
Clear skies. Lookin' good for comet hunting... Bloody cold though.

Moon near Jupiter (Etobicoke)
Spotted the gibbous Moon near Jupiter. Maybe 6° apart. Fairly clear out. And cold.

Moon bookends (Etobicoke)
Huh? What was that glow across the street? Oh. The Moon. Right, it was close to a full Moon.
It was very low, a bit yellowed. The sky was hazy with high cloud.
I was momentarily disoriented. It was setting; not rising. Perhaps because I was heading north now on my walk to work?
Jupiter was shining despite the wispy clouds. I could see Regulus. Further apart than when I had seen them in December.
§
Oh ho. The full Moon was back. Up high, in a dark bitter cold sky, left of Orion. Now on my walk home.
Briefly considered setting up.
Ah no. Not at -19.

added a fast-moving NEO
Learned of NEO 2004 BL86 today and that it will be moving very quickly by us on Jan 26. While reviewing Mitsky's January 2015 Celestial Calendar, I decided to add 2004 BL86 aka asteroid 357439 to SkyTools. Was rusty at first. Could not recall how to do it exactly. In the end I did a regular search, that is, I used the Designation Search Tool. Entered "2004 bl86" and it popped up. Added it to a new list. Done. Then traced the path.
Bookin'!

software and sci-fi
Joined Elaine and Tony for dinner, drinks, and holiday fun.
We wanted to do some observing. It was clear for the beginning of the evening. But after dinner, we were clouded out. Even the DDO called off their tentative tailgate party.
Helped Elaine update her SkyTools. We downloaded the latest version. We updated the current comet, minor planets, and supernova lists. Then we checked Lovejoy's current position and tracked it for the next couple of weeks. We checked the field of view settings. We added a couple of eyepieces. And I created a custom entry for the Canon 60dA.
Later, we stayed warm by the fire stoked by Elaine and watched old movies. The last of which was Rocketship X-M. Funny and yet fascinating.
