NGC 7810 & Crew with Asteroid ...

Back on 2012/11/10:



I was really just looking to test out the camera and off-axis guider.  The skies were clear, but I needed to dodge the trees and found this on the fly.  Turns out there was an asteroid that +Mike Rector helped me find as 771/Libera.

I put the image down for a while as I didn't get the time for fundamentals like calibration files and a good processing routine down.

Turns out there are more hidden gems in this image.

According to WikiSky and some of the UCAC3 catalogs in SkyCharts/CdC, some of the dimmer but still recognizable stars are mag 17.5 or dimmer or beyond.  I count at least 10 by quick count and according the CdC there are the following in this FOV:

What's truly amazing is HOW many fine details are hidden in a 'quick' 30 minute exposure of a simple, boring area of the sky.

Trying to dig deeper on some galactic stats I found this site:
http://cseligman.com/text/atlas/ngc78.htm#7803

Here the larger and brighter (closer?) galaxy, NGC7803 is estimated at 250 MILLION light-years distant.  Some of the other's I cannot find stats for.  Does this mean they are not measured???

Thanks for reading to the bottom, bonus candy for you!

Finally a respectable M81/M82



I had to try my budding DSLR skills again.  I had to, the moon was new, the weather is cold with low humidity and the seeing poor (aka no planets).

I fought the typical equipment issues and unforeseen weather, the weather didn't kill me too bad, just a bit.  Clouds came out of no where for 30min then went away.

I learned some things, such as how to tie a knot in your power connectors:

http://www.instructables.com/id/Plug-Extension-Cords-Together/

The UPS didn't protect the USB connectors from loosing sync, so I had to realign and then later I unplugged the focuser as the focus was soft, and ooops, that was the mount again not the focuser, so I gave up.

Sigh.  I'm learning that ISO1600 is less noisy but good signal over the 6400 I was using before.  Mixing ISO's isn't very good, I won't do that again.

Guiding could be better, but I was good for subs up to 5min.

I know I can do even better now that I have some good experience under my belt.  I also have the AC-adapter for the camera now too, so I can go hog-wild!!

Full res is here:

Previous work with the 6" and NO experience here:
http://astromaphilli14.blogspot.com/2009/02/my-1st-light-with-new-setup-m81m82.html
I think I may have to sell the 6"!!!

Thanks for looking and reading!

Strange S-shape feature on Jupiter 20130119

Around the L2=70 area in the SSTeb (Lower Right). Also there is GRS Jr near the 3 white ovals. I caught a rare winter steady skies. To me the key has been low surface winds and minimal temperature drops. Despite a mild jet stream these 3x(20s@RGB) sequence came out well!

High Resolution Asteroids Ceres and Vesta

My collimation is quite out due to some slag in the optical train that I think I have since fixed.  I was hoping to replicate and beat the previous work I've done on Ceres (http://astromaphilli14.blogspot.com/2009/04/moon-m45-mercury-then-saturn-and-ceres.html)

Believe it or not, Ceres is not much smaller in angular size than the Jovian Moons and is shown in my recent 2012 feeble attempts to not have a stellar airy disk.  Vesta shows a bit more oblong / elongation and I'm not 100% convinced it is real as my collimation was out by too much for my taste.  I hope to try again in 2013 with better conditions!
