Hi,
Since a month I've discovered KStars and the Ekos & Indi packages and I'm impressed with the functionality it brings to my Linux system for doing astronomy/astro imaging. Keep up the great work!
As the weather is currently cloudy at my place I was experimenting offline with the plate solving part of Ekos, but I haven't been succesful so far.
I've downloaded the data for
offline solving and it works when I solve from the command line, but doesn't give any solutions when doing this from within Ekos.
When I point the telescope simulator close to M31, the solver options show the following options:
--no-verify --no-plots --no-fits2fits --resort --downsample 2 -O -L 160.837 -H 266.651 -u aw -3 10.9042 -4 40.9589 -5 10
Image size (4x2.5deg), RA, dec and range seem to be OK and when I try to do a "load and slew" on a DSLR image of M31 the log window shows the following logging:
2016-11-05T19:17:29 simplexy: found 2928 sources.

2016-11-05T19:17:24 FITS header: Cannot find FOCALLEN.
2016-11-05T19:17:24 FITS header: Cannot find OBJCTRA. Using current mount coordinates.
After waiting a few minutes it fails (no solution).
Passing the Ekos solver options on the command line to solve-field gives me a solution within a few seconds.
So the options and solver installation seem to be OK.
From the logging however it looks like the it uses the wrong solver options: they are not correctly passed from Ekos to the solver as it seems to use RA=359deg and dec=180deg.
Does anyone know if this is caused by the fact that I'm using the simulator, or by incorrect Ekos configuration, or is this a bug in Ekos?
Thanks in advance,
Martin
