Here's another go on this subject. I was able to get to a "slightly" darker site than my backyard in the last version with 24 minutes of data.
This version is 160 minutes of data.
ZWO 1600mm cooled camera
160 x 60 seconds, 16bit FITS, sensor cooled to -20° F below ambient.
Processed with Astro Pixel Processor.
I'm happy to say the black bar issue I had in the previous version was not visible in the 16bit FITS.
