M81 & M82
Apr 16, 2015 13:55:19 #
These are my first photos with the Celestron AVX Mount tracking.
I was more concerned with the mount tracking than I was with the quality of the photo work.
The first shot is both M81 & M82 being on the right side.
Nikon 800E, Meade 8" f/10, ISO 1600, 30 sec,
2. Same setup only focused on M82 and Cropped.
3. M82 Canon T2i Converted filter to H-Alpha, f/10, ISO 800, 30 sec.
4. M81 Same setup with T2i

Certainly looks like you are almost there. Mostly round stars. I see ovals in the last shot. Looks good.

Thank you Jim and yes you do see ovals in the last shot. It was taken 2 nights ago on my first attempt at photographing off this mount. I still have a lot to learn about it.

A gem mount and well on your way to other worlds.
No doubt bodes and cigar galaxies. :thumbup:

Thank you for looking in Astroturf. Although not quite there yet getting better. Looking forward to seeing your work this year too.

Looking really nice Craig. Figuring out and playing with the equipment is half the fun. If this was easy everyone would be doing it. Do you take darks, bias and flats to improve your signal to noise?

Thank you Matthew for looking in. On these shots I just did singles at
different Shutter and ISOs to see how the guidance was working.
I did get a fair amount of star trails at 2 min and above.
Once I get that dialed in I'll start working on stacking again.

I might mention that I did my first stacking experiment lat night. Downloaded the latest DeepSkyStacker program, and this time it ran without crashing. I think the prior version didn't know how to read my Sony A99 RAW files.
I didnt get out the equatorial drive, so I just used Polaris. Stacked 24 images, without dark frames, and let it run. Then post processed in Photoshop. What immediately saw was that 16th magnitude stars that previouly were dim fuzzy dots were now very sharp. Of course Polaris was completely blown out.
But I am encouraged by the first try.

Hi Jim. Did you post this set yet.

I didn't post it yet. I'm at work now, and I might try a second time tonight. Then I'll post.
What I immediately noticed was it is doing an even better job at lowering the noise level than in-camera Multi-Frame Noise Reduction. The histogram produced by stacking is a very narrow spike now.

Thank you Tom for the comment and appreciate you looking in.
Big New Moon Star Party on Mt Figueroa tonight for VAAS.
