M63 LRGB with the Starshoot G3

Finally, I had a good clear night and had enough time to image something properly with the Starshoot G3.  This time, I thought I would shoot a galaxy, and I chose M63 because it is a tightly wrapped spiral with a lot of fine detail.  Although this object would fare better using the 8 inch, being I'm still learning how to use this camera, I used the 6 inch.  The 8 inch's field of view with this camera is substantially smaller, and I really didnt want to mess this up with tracking and framing problems.

The 6" still showed quite a bit of detail.  I might have done a little better with more, shorter exposures, as the core is blown out.  However, I got the fainter extreme outer regions nicely with these 5 minute subs.

This was my first processing attempt.   These images are much more difficult to process.  I do believe however, that this camera is the way to go for smaller objects.

This next image was restacked, and reprocessed.  I took 20 dark frames and was able to go a little deeper.

I may have lost a little detail in this one, but I like the color better, and I got a little more of the outer regions of the galaxy.  I cannot figure out why the images are flipped vertically.  I didnt flip them, but I noticed in Fits Liberator, some of the frames were flipped and some were not.  I dont recall the exact processing workflow I used when producing these, so it might have something to do with the original fits files.
