Description

"First light" of my new QHY163m (not technically first light, but this is the first image where the working distance was nearly correct). I was pretty blown away by what I was able to get from just 5 frames...

The artifact around Alnitak is apparently a known issue for these cameras (including ASI1600) and is supposedly caused by the cover plate on the chip. Seems to also depend a lot on the imaging train, filters etc. For 10min subs, I can live with it - probably fixable in photoshop.
