Summary: Meridian flip not working consistently
Product: kstars
Version: 3.5.2
Platform: Ubuntu Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com

Target Milestone: ---
SUMMARY
Over the last few weeks I have noticed that Meridian flip is not working
consistently. My setup is Raspberry PI4 running Astroberry version 2.0.3 which
I run as a server at the telescope.The equipment at the telescope end is:
Skywatcher HEQ5Pro so using EQMOD for that
2 ZWO cameras one for capture the other for guiding
Lakeside focuser
ZWO filter wheel
PHD2 for guiding
I am remote controlling the PI with Ubuntu Mate which is running inside the
house. KStars/EKOS runs fine with this setup and has worked flawlessly for
months. I always ensure I keep everything up to date and have a spare PI that I
use from time to time too.
I first noticed an issue with meridian flipping 29/03/2021 whilst tracking the
sun and had to force a flip. Then when using the scope to image an Ha area in
Cepheus I noticed again it did not flip. I then set flip to 0.01 hours after
meridian to speed things up. It seemed to sit there for ages doing nothing
apart from stating "Waiting for flip". Again I forced it to flip and continued
with its scheduled jobs.
Then I tried flip during the daytime and it worked ok but this time I had mount
and indi logs enabled. That night I tried for my target again and found that it
was stuck at the same point. I reinitiated the flip manually at around 03:45 at
which point it captured 2 subs before the clouds finally set in and I had to
abort it completely.
I attach the logs for your perusal. This log also contains the good test flips
during the day as well as the "failed" one. The settings at that time were 0.01
for flip but I subsequently reverted back to 0.1 hours for flip. Same results.
More recent update 21/04/2021 I have been unable to fix this issue. I have
reset the mount to factory defaults. It has auto-meridian flip set as a
default.
I rebuilt my Linux machine and installed the latest version of KStars 3.5.2
2021-03-01 and tested. Meridian flip worked, once, then would not work again.
When it reaches the meridian + 0.1 it states "Meridian Flip Planned". No
further captures take place and it just sits there and does nothing.
However I have found that if I uncheck the Meridian Flip if HA>0.1 before a run
and then check it again then it will meridian flip during the run - hence the
title of my topic.
I see from the changelog that there were a number of changes made around the
meridian flip part. Is it possible that something has gone awry?
