Description

M81 Galaxy Group Widefield Jan 2018 Back yard

Borg 125SD f/3.9 (488 mm) + ZWO ASI094c imaged in the wee hours of 1/20/2018

CGE Pro Guided

Poor guiding (RA oscillations)

15 x 900s + 24 x 450 s = 6.75 hours of exposure

HDR combined, ABE, MLT denoise, masked stretch, TGV denoise, HDRMT, Star mask+Morph star reduction, more HDRMT, curves

Overall disappointing! Weird color balance (all yellow and blue, little red)
