The two times I've ever tried imaging this galaxy have been on nights of exceptionally poor seeing. CloudFreeNight showed the deepest reddest jet stream over Heathcote and I figured I'd brave it and see what I got. 4" seeing deconvoluted down to 3"
1 hour of each RGB, I'd set up for 1.5 hours of luminance but the driver on my QHY163 crashed, had the USB Traffic set too high.
I've created a synthetic luminance from the RGB and done what I could. Mostly wanted to play with the new PhotometricColourCalibration, had it set at G2V which gave the most accurate results, using a galaxy setting had the spiral arms a bit too blue.
Higher Res
Has nothing on the resolution that some have achieved but then again, you cannot polish a turd
Noise reduction has been extensive. Don't know why this has been my default bad seeing galaxy two years running
