Bug ID: 406446
Summary: Ekos fails to recognise Astrometry index files
Product: kstars
Version: 3.1.1
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: mutla...@ikarustech.com
Reporter: z...@zjbnewton.myzen.co.uk
Target Milestone: ---
SUMMARY
Ekos reports Astrometry index files are missing when they are present and
"Capture and Solve" fails.
STEPS TO REPRODUCE
1. Open KStars
2. Click on Ekos
3. Select "Simulators" profile
4. Start Ekos
5. On telescope tab unpark telescope
6. Click on Alignment tab
7. Set field of view to 128'x 96'
8. Click "Capture & Solve" button
9. Look at reports in process window.
OBSERVED RESULT
After "image received" report see error message reporting that index files 4205
to 4211 are missing. Astrometry solver fails to solve image.
EXPECTED RESULT
Expect solver to give solution to location of Polaris in captured simulated
image.
SOFTWARE/OS VERSIONS
Linux mint 19 Tara:
Kstars version 3.1.1
ADDITIONAL INFORMATION
Recently tried KStars/INDI/Ekos for first time. I was running indiserver on a
RPi3B+ connected to an HEQ5 Pro and a ZWO ASI185. The camera was on a Celestron
C8 with an f6.3 focal reducer giving a field of view 19.6' by 12.4'. I was
controlling the set up using a KStars/INDI/Ekos client (Kstars version 3.1.1)
running on a 64bit laptop using Linux Mint Mate 19 Tara.
Telescope control using INDI and the KStars star map worked fine with the
telescope slewing to the target (Arcturus) and tracking.
I ran into problems when trying to use the Ekos Alignment module. The "Capture
& Solve" function failed to solve repeatedly. Ekos produced a warning that the
Astrometry index files 4200 to 4205 were missing. The laptop had a complete set
of the Astrometry files from 4200_00 to 4219 (as did the RPi) and these could
be accessed via the alignment module options/Index Files buttons. The camera
was taking images (via the camera module) and these showed several stars. I
slewed the telescope to Vega to try a different patch of sky but got exactly
the same results.
The following night I tried again with the same set up. By mistake I set up the
field of view in the alignment module to a lower value (13' by 9.8') and the
error message this time reported that files 4200 to 4204 were missing (not the
4200 to 4205 when the field of view was set to 19.6' by 12.4). Otherwise the
results were as before with the astrometry solver invoked by "Capture & Solve"
never solving.
Later I tested the laptop and its software alone using Astrometry accessed via
the "solve-field" command. The program solved location using images of M31 and
the Pleiades.
I then tested the laptop with KStars/INDI/Ekos using the "simulators" profile.
With the alignment module field of view set to 128' by 96' invoking "Load &
Solve" produced an error message that index files 4205 to 4211 were missing.
The solver completed satisfactorily, however, and the simulated telescope
slewed to the correct target (M31). The automatic "Capture & Solve" follow on,
when the module took a simulated image of the sky, repeatedly failed to solve.
Attempting to "Capture & Solve" using the simulated camera always resulted in a
failure to solve.
Re-installing kstars-bleeding does not remove the problem.
The Ekos warning about missing index files seems to be a bug. Whether the
failure to "Capture & Solve" results from the same problem is not clear.
