Hi,

After a one year pause I dusted off my equipment. Installed stellarmate on my new Pi. Did my first session and wanted to take flats in my usual way through Ekos using the flats option and have Ekos calibrate to my desired ADU of 25000.

Tried this with my ASI1600MC and ASI294MC-Pro.

Ekos starts taking frames, then decides on the exposure time to fit my ADU setting, then the next image is taken with the calculated exposure time, then calculates the ADU and this is more than double the ADU you would expect so it discards the frame and starts calibrating again, It will do this indefinitely.

Here are some examples, same exposure time, m22-01-20T22:54:10 Download Time: 59.00 s, New Download Time Estimate: 36.83 s.

Just to make sure it's not my stellarmate setup causing the issue, I installed Ekos in my Ubuntu desktop, latest stable version. Same issue.

Anyone familiar with this?

Appreciate your help.

Thanks,

Marco
