Bug ID: 418159
Summary: Polar Alignment Fails
Product: kstars
Version: 3.4.1
Platform: Other
OS: macOS
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com
Reporter: mountainai...@outlook.com
Target Milestone: ---
SUMMARY
Polar alignment tool fails because it attempts to rotate more than the
specified number of degrees, hitting the mount slew limits before taking the
second of three image.
STEPS TO REPRODUCE
1. Roughly polar-align Celestron CGX Mount
2. Go to Alignment tool.
3. Choose Polar Align
4. Choose East/West (I used West) and accept the default 30 degrees of
rotation.
5. Start
6. After taking first image, mount will slew to its limits (something like 100
degrees) and will not be able to take its second image.
6. Strangely, if I change this to 25 degrees or even 28 degrees, it seems to
work fine.
OBSERVED RESULT
Using the default of 30 degrees, the mount slews to its limits after the FIRST
image (in excess of where it should be even if it had taken all three images).
EXPECTED RESULT
Mount should slew 30 degrees for each rotation, and no more.
TO OTHER OBSERVATIONS
1) Polar Alignment tool attempts to park mount when aborted; please make this
configurable. I would rather it go back to switches (NCP).
2) Polar Alignment tool seems to have difficulty plate solving some images.
Are there recommendations as to how close or far away from the NCP you must be?
I have every index file downloaded and never seem to have problems plate
solving other areas.
