Bug ID: 423916
Summary: Flat Focus Position Not Used
Product: kstars
Version: 3.4.2
Platform: Other
OS: Other
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com
Reporter: mountainai...@outlook.com
Target Milestone: ---
SUMMARY
When shooting flat frames, Ekos does not return to the last-used focus position
for each filter. The positions are stored properly, Ekos just doesn't attempt
to focus prior to starting the exposure.
STEPS TO REPRODUCE
1. In focus module, run auto-focus for all filters of interest.
2. In camera module, click Filters icon to verify that each filter's focus
position is recorded in the "Flat Focus Position" column. I also had AutoFocus
checked, and lock filter unchecked.
3. In the camera module, choose Type=Flat. Note, I also use the calibration
wizard in manual mode with an ADU of 28000 and a tolerance of 1000.
4. Add one exposure of at least two filters to the sequence.
5. Note the current focus position in the focus module. If desired, change it
to some distant number so it's obvious if it changes or not during the flat
capture (e.g. 20,000).
6. In camera module, click start on the sequence. Note that Ekos change the
filter, but doesn't seem like it adjusts focus according to the log. HOWEVER,
note that manually setting focus in the Focus module also doesn't leave a trace
in the log.
7. In the focus module, note the focus position doesn't change between filters.
8. In the Indi Control Panel, note the focus position doesn't change between
filters.
NOTE: THIS ALSO HAPPENS WITH THE SIMULATORS.

2020-07-05T18:47:30 Warning: Guide deviation is selected but autoguide process
was not started.
OBSERVED RESULT
Flats are shot without Ekos adjusting focus.
EXPECTED RESULT
After changing filters, the flat capture module should adjust focus to the
level recorded for previous light frame exposures for that filter, prior to
initiating an exposure.
