Description

First light with asi 183mm at 0.5"/px imaging scale.
Guiding this night was better than ever but still lots of fast oscillation in RA keeping my stars flat and oblong. My cgem's RA is certainly not up for the task, but a bit of motion blur decon did help a little.

For comparison, here's a 6 hour integration from my OSC camera that has a twice as big image scale:
