Description

The frequently imaged Whirlpool Galaxy never disappoints. This data represents for me a breakthrough where I finally found a combination of imaging settings that greatly reduce the fixed pattern noise and effects of residual bulk image effects in the Aluma AC4040 camera based on the Gsense 4040 sensor. While the measured FWHM of 3 arc-sec revealed that seeing wasn't the greatest while I was gathering the data, I'm fairly happy with the amount of detail I was able to coax out of the data. I've spent a few data processing this one and I't time to move on. Feedback is always welcome.
