Description

working on optimizing the exposure time with the nexstar mount. This is taken using native focal length (f/10) and a small pixel camera (svbony305, 2.9um).
The mount tracks exceedingly well in Azimuth but the Alt axis wobbles up and down quite a bit, so it seems 5" is the max to get almost 100% round stars. 
Image collected in two sessions (both cut short because of the marine layer), total ~1.2 hours.  
Registration used the 2 star method of Siril since at this short exposure time not many stars are resolved in the limited FOV.
