Two clear nights in a row!!! It usually does not happen in Reno, NV. After successful imaging of Elephant Trunk the night before, I imaged NGC 7331 Deer Lick Group plus Stephan’s Quintet.
I was very lucky to barely get NGC 7331 and Stephan’s Quintet in the same FOV.
The whole imaging session was never interrupted and worked flawlessly.
Used Windows 10, SGPro 18.104.22.168 and PHD2 2.5.0dev4.
