KStars log

This is in KStars 2.7.8 for Windows.

While testing meridian flip, I observed Ekos initiating an exposure while the mount was still slewing.

(timestamps kept in UTC)

Scenario is:
- Track alpha Coma Berenices, RA=13.1804 DE=17.4407, starting at 18:53
- At that moment, alpha Coma Berenices is 6 minutes from the meridian
- Setup 8 exposures using the Ekos Scheduler, uncheck Track, Focus, Align, Guide, Alt and Twilight, using prepared sequence of 1x120s exposure, meridian flip if HA>0.
- Start scheduler, and wait for the meridian flip to occur and check Ekos behavior

Observed:
- 19:00:33 At the end of the second exposure, Ekos sends new coords to mount because the HA exceeds 0 (0.02h)
- 19:00:37 Ekos restarts exposure, but mount is not done slewing (exposure is therefore being corrupted)
- 19:01:31 Mount finishes meridian flip
- 19:02:37 At the end of the third exposure, Ekos sends again new coords to mount because the HA exceeds 0 (0.05h), apparently the previous meridian flip wasn't taken into account
- 19:02:38 Mount is done slewing
- 19:02:41 Ekos restarts exposure

To summarize, first flip request is not waited for, and an unexpected second flip request occurs, which is waited for.

On hold since much has changed in INDI/Ekos during that year.
I'll provide more information later on.

Probably not. I'll test this during January if weather agrees.
