Hi Ballard, thanks for your comment.
ASKAR 120MM F7APO with field flattener, Canon R6, ISO 12,800 6X30sec subs mounted on a Celestron AVX mount. Of course that is 180sec of lights, 180 of darks, the flats were shorter and bias frames much shorter. I processed in Siril v1.21 then a bit more in Topaz
I was out in the AZ desert 50miles north of Douglas AZ at the Tucson Amateur Astronomy Association CAC site. This is a pretty dark location with class 2 Bortle skies.
That sound like a great location. I'm in Bortle 4 here in Grass Valley and recently the Jet stream had made for bad seeing.
