I was experimenting with the scheduler last night. A simple schedule with only align (no guide, no focus) and a very simple sequence of 2 captures.
I noticed that after align is complete, the first capture starts immediately, however my telescope is doing the final re-position slew at this point in time.
The result is the first capture has trailed stars. It could be some issue with my setup maybe. I'm using the celestron_gps driver.
Here is the log from the scheduler. Alignment complete at 20:38:22 and then it starts the first capture straight after this. However I think my mount was still moving from 20:38:22 to 20:38:27
