Imaging Camera: Qhyccd 183M Back Illuminated ColdMOS Camera at -20C
Imaging Scope: Sky-Watcher 8″ Quattro F4
Mount: Sky-Watcher EQ8 Pro
Guide Camera: Qhyccd QHY5L-II
Guide Scope: Sky-Watcher 90×50 Finder
Filter Wheel: Starlight Xpress Ltd 7x36mm EFW
Filters: Baader Planetarium LRGB + 7nm Ha
Image Acquisition: Main Sequence Software SGPro

Image Details:
101x150S in LRGB, Total 16.83 Hours
25x300S in LRGB, Total 8.33 Hours
25x600S in Ha, Total 4.16 Hours
Total exposure time: 29.32 Hours
BIAS, Darks and Flats subtracted

M81 and M82 Galaxies in LRGB+HA

1 Comment

By far my biggest challenging project to date, maybe not by image acquisition, but by processing.  The above two galaxies caused me lots of grief when trying to process, they just did not come out right with my normal method of processing, so I turned to PixInsight to process them, and I anm so glad I did, the whole learning curve put me back to almost the same level I was at in 2008, but the steep learning curve paid off
