Hi,

Is there a known issue with flat calibration and setting the time to infinity?

It is not clear why it happens.

Steps to recreate:

1. Set sub to Flat
2. Set ADU to 12000
3. Set exposure to 1 sec
3. Start capture

Some times the calibration works, sometimes now. Editing the exposure to reset the value and redoing until a value allows it to work, was the work around.

Once the sequence was created and saved, rerunning the sequence still resulted in 2 of the seven filters needing to have exposures played with.

Any ideas?

I do not know what camera you use, but with my ASI1600 I had a similar issue where it couldn't figure out the right exposure time for the ADU I wanted. I set the exposure to start at 0.5 seconds and the problem never resurfaced.

I added more debug logging for this feature in the next KStars release so hopeully we'll know what's going on. Basically, after the 2nd capture, it tries to do llsq/polynomial fitting for the data to get the optimal exposure, so something wrong went there. When we have the logs in the future we might know why and fix it.
