This is the first real night test for an adaption of my Pentax lenses to the ZWO 7x36mm filter wheel and the Zwo cameras of mine.
The DSO image is not much processed as it was just a test.
66 x 200s HA @ gain 139 Pentax DFA 50mm @ F/2.8 Macro at ZWO ASI1600mmp.
The whole stuff is mounted on top of my "normal" gear.
...at night with moon an Jupiter behind...
Though I had expected some I was surprised by the presence of so much signal in that region. The Crescent, Pelican and North America nebulae can be found in the frame. Obviously there is a lack of sharpness. The lens was full open and I could have taken more time for the manual focusing. My Bahtinov masks did NOT work.
APP for preprocessing and PSCC2019/LR for the rest. This was just a quick processing because it was only a test. Next time I plan to stop down the lens a bit with stop down rings.
