M81 Bodes & Cigar

[Notty]

2 hours of Luminance, 40 mins each of RGB, dithered in PHD best 95% stacked with darks, flats and dark flats, ASI1600m ED80-DS processed in Star Tools. Now the thing with this is I started my guiding and it was just awful, although to be fair it warned me calibration was too far off the CE to be reliable but I did it anyway just to start harvesting. I was getting about 1.1rms, so I wondered if I binned everything 2x2 it would help, though I'm still trying to get my hear around the science.  I wonder sas this is a valid approach under crappy guiding/seeeing? I think it means I end up with a effectively very expensive DSLR haha! I'm quite pleased with the image for my standards anyway. I put the slightly cropped one up as well. Thanks for looking.

Nice image!

Of the two, I prefer the uncropped version, with the extra galaxies.
