I had a frustrating time trying to image Comet Lovejoy. Because it is moving, I manually acquired the target and framed the shot before starting the sequence. The target was 15 minutes past the meridian when I started the sequence. The mount was on the correct side of the mount for an object west of the meridian. I had unchecked the Slew and Centre options for the target, and I had unchecked the auto-meridian-flip setting.
When I started the sequence, it immediately tried to take a plate-solving shot and slew the mount. I aborted that operation, at which point it told me that I was aborting a meridian flip! Why would it be trying to do a flip when the target was already past the meridian, with the mount already in the correct orientation?
Not only that, but when I confirmed that, yes, I did want to abort the flip, SGP failed and shut down. I ended up reverting to Nebulosity to get my sequence.
I am using a CEM60 mount. The ASCOM driver for the mount is version 2.4.
