better colour

Went back to Registax and tried the recipe at Garden Astronomy.

Well. That's the best yet.

tried at home

Wasn't happy with the results from the afternoon. So, now at home, tried AutoStakkert again. Then Registax. This time I tried following the steps in the tutorial on the Awesome Astronomy web page, in particular, using these Registax wavelet settings. In general, I had not gone above 0.100 on the sharpen options. In fact, I forgot you could.

Mimicked the main settings.
  • Automatic: on
  • Hold Wavelet Setting: on
  • Initial Layer: 1
  • Step Increment: 0
  • Wavelet filter: Gaussian
  • Use Linked Wavelets: off
Then tuned for my eye (layer. preview, denoise, sharpen).
  1. 48.4, 0.20, 0.120
  2. 51.5, 0.10, 0.120
  3. 69.3, 0.10, 0.120
  4. 36.8, 0.00, 0.110
  5. 15.3, 0.05, 0.110
  6. 92.0, 0.05, 0.110
Ended up with this.

Huh. How about that.

enjoyed the dark side

Asked Tony if we could drop into the LCBO at Southdown and Royal Windsor. Sure.

Found what I wanted in the Vintages section. Only two bottles out... Lucky.

Dark Side of the Moon by Claymore Wines, from the Clare Valley, Australia.

We cracked it open at dinner. A stunning shiraz, heady bouquet, full bodied taste, intense, thick deep long flavours. My cup of tea.

And done way too fast.

Tony liked it.

readied for more processing

Prepared for the meet-up today. Downloaded AutoStakkert! version Requested to join the AS Yahoo!Group. Learned that AS does not offer wavelet control. Oh. Downloaded WinJUPOS. To help with derotation. Requested and received Christophe Pellier's small e-booklet on successfully capturing planetary images. Copied these items to my external hard disk. Read a bunch of articles on stacking and wavelets. Re-read Medhi's blog post.

Starting forming a plan. I would try stacking in AutoStakkert to see if we could get a better result. I'd try to apply derotation to the images. Guess we'd continue to use Registax for wavelets...

no X (Toronto)

Took at peek at the Moon through the small refractor in the OSC parking lot. I did not see Lunar X.

delivered TSTM

Delivered my The Sky This Month presentation at the Ontario Science Centre for RASC members. For the balance of February and most of March 2015. Provided a photocopy of my special calendar. 100 copies made.

Photo by my buddy Nicole.

Highlights include:

25 - Lunar X
28 - Handle on Moon
    - lambda Gem occultation
13 - Moon, Saturn, Antares (am)
20 - new Moon
    - very young Moon?
    - start marathon?
    - zodiacal light and Gegenschein
21 - Moon near Venus
22 - day-time Venus
24 - Moon in Hyades

and Jupiter "events" galore!


Posted the calendar, notes, infographics, and photographs on the RASC Toronto Centre web site.


Updated my archival presentation page over at the companion.

brief observing (Etobicoke)

Took me two blocks and Distant Suns (Lite) to find Mars, ½° to the bottom-right of Venus. Close!

Bright crescent Moon up high.

Jupiter over the roof of the house.

Cold. Very cold. Again.

corrected GRS in Stellarium 13.2

Chris asked me to look into the Great Red Spot positioning in Stellarium. He thought it off again. After a lot of fiddling in Windows 8.1 with Stellarium 0.13.2, I settled on a rot_rotation_offset of 90.


JUPOS showed the GRS around longitude 222 or 223°. I updated my SkyTools 3 Pro to 223. It showed the GRS transiting around 11:50 PM tonight.

Sky and Telescope's online calculator (in the interactive tools area) said the GRS would transit around 11:35 PM tonight. I wondered how current this data was.

I found Stellarium set to 310.

In version 0.12.4, I found I had to use the value 280... Weird.

chopped and centred

Tried stacking and adjusting the wavelets.

8:08 PM. Test 1. Manually cropped.

Weird seams. I wondered if it was due to the significant drift. Something with the JPGs?

10:11 PM. Test 2. After centering and cropping with NINOX. After preparing BMP frames for NINOX!

Better, no seams! Ugh. But over-processed.

Test 3.

OK. Looked

more Registax info

Elaine and Tony referred me to the section Processing Your Webcam Images from the book Digital Astrophotography by Stefan Seip. Published by rocky nook. Registax tips. OK. Some reading to do...


Unfortunately, the book refers to an older version of Registax...

finally, got files

Tried again with TeamViewer 9. Elaine made her machine the host. I jumped in, found the files, and transferred them over. Easy-peasy-lemon-squeezy. Now I have the three "bla30_2015-01-24-013838" series files, segments 0000, 0001, and 0002. The first two are 2 GB each, the last was 122 MB. That represents the 1200 frames captured just before the triple transit was clouded out.

could not transfer file

Tried to transfer the Jupiter AVI files. Large, at 2 GB, each. Elaine and I tried FileZilla Server 0.9.49. No joy. We tried TeamViewer 10. No joy. Damn it.

fixed Rainmeter finally

Fixed Rainmeter for my gCal feed. Huh. It turned out to be an issue of case.

Changed the text string from "full" to "basic." No joy. Then to "Basic."

tested small battery

Performed a "full" test of the NOCO genius BOOST GB30 li-ion battery. I wanted to see how it might hold up if used to fight off dew from a camera lens. Admittedly a usage different than what it is designed for.

I connected the Kendrick type VI dew removal controller to the jumper clamps, careful of the polarity. I connected a "classic" 2-inch dew strap. I turned on the controller at maximum power, full power. And verified the heater was hot to touch.

It ran for approximate 5 hours and 53 minutes. And that was not from a full charge... Not bad... not bad at all.

happy day!

Wiarton Willie calls for an early spring. Apropos as Toronto got dumped on. Happy Groundhog Day!
