This issue has troubled me for a few nights now...While there is a capture ongoing meridian flip initiates.

I've set my hand controller to flip >5 deg and Ekos to flip at 0 deg (HC for fail-safe).


Tonight as you can see while capturing a 600s frame, the meridian flip started without waiting - while the capture kept going. After the MF was completed I stopped and restarted the Scheduler.

What am I missing?

Does 3.6.6 also exhibit this issue?

Dear Euripides,
it looks like there is a slew from outside of KStars/EKOS at 2023-08-03T01:04:37.229 EEST. It’s definitely not the slew from the EKOS meridian flip logic. The latter starts at 2023-08-03T01:06:08.326 EEST.

Therefore I‘m pretty sure that your mount issues this first slew - but no idea why.

I would recommend testing this during daytime with the mount, but maybe with CCD Simulator.

HTH

Yes, waited the update to retest and the issue remains.

I thought that it was caused from my HC, that’s why I‘ve changed the value to flip at 5deg while Ekos at 0.

If it’s not a bug, it has to do with my HC’s time?

Correction: I thought I set the HC meridian treatment at 5 deg. As soon as Ekos loads up, settings on HC sync with Ekos!
Changed the battery too to be sure but I saw that all the settings, time etc were correct.
