Andromeda Galaxy Fin
I think I'm finally satisfied with an attempt at this target, everything went well with my focus, temps were low and the skies were very dark at my family cabin near Stanley, Idaho. Earlier in the day was a fantastic solar eclipse and since I had the telescope setup I figured I'd keep it in place and capture the Andromeda Galaxy. I managed to have everything setup and ready to run by astro twilight, guiding was good for a chance (less than 1" total RMS), everything worked out to get the exposures over 5 hours and I didn't forget any equipment.

Polar Aligned with Sharpcap, pulse guiding with EQMod and PHD2.
Imaging acquisition done with BackyardNikon
52 light frames at 5 minutes each, ISO 1600
31 flat frames, no darks or bias frames
PixInsight used to do flat frame calibration, debayering, subframeselector, registration, localnormalization, and drizzle integration.
In PixInsight I then did a channel extraction for luminence, split the image into RGB and LinearFit each RGB to luminence. After that I did a colorcalibration and then a screentransferfunction (didn't even do a background extraction since there was no gradient and a very flat field after flats calibration).
In Photoshop I did some contrast work with curves, saturation, a high pass filter to generate more local contrast, levels to bring down the black point/background, then a star size reduction. In Lightroom I did some noise reduction and sharpening before exporting.
Now it's time to work on something new....if the skies clear up again.
