Description

I parked the scope on M81 while testing different configurations of my optical train. Combined luminance from last year with new RGB and Ha data (shot during full Moon) for my longest integration time on a single object. 

Ha was processed with continuum subtraction. The IFN came out really nice after noise reduction with DeepSNR (from the author of StarNet). Didn't expect that from my Bortle 7 backyard.
