Just updated kstars and it crashes when starting a sequence file. I noticed this first last night using the scheduler. Couldn't capture anything in the schedule.

Tried to take calibration frames today during the day and its crashing when I start the sequence file. Screenshot and backtrace below. Any idea what I'm doing wrong? I'm using a sequence file that worked with the previous version (also attached). Feeling its something filterwheel related.....

Aaaaagh. As soon as I reported this I just figured it out.

Turns out my filter wheel was missing for some reason from the 'primary' optical train settings.

Not sure if I should delete this post?
I think Kstars should probably report an error if a sequence that requires a filter is used and the filter or filter wheel is unavailable instead of crashing.

Just tested and Filter dropdown is disabled when there is no filter wheel in the optical train... so it's odd it wasn't disabled in your case.

I loaded an old sequence file though. That sequence file had filters specified. Maybe it shoudn't have allowed me to load the sequence file.
