This is precisely the reason I wrote the original camera simulator, it allows lots of testing and development on those cloudy nights.

In case of tests for astrometry you need installed gsc, then you'll get nice images to test

An excellent point and one well made.

I do have that set up, gsc et al, as I was using it earlier. Slipped my mind!

I had the problem with non-solving offline solver in EKOS too. Your wrapper made it work! Thanks a lot!
Is there a root cause or a clean solution available yet?

I've not seen a recurrence since my initial work around, to be honest, so I never got to the bottom of it.

It does seem a strange one, doesn't it? Perhaps some kind of timing issue/race condition and the wrapper simply adds a couple of milliseconds delay whilst it fires up bash?

Difficult to see where it could be coming from, though.

Hi!

Suddenly I have the same problem, and your little wrapper seems to have solved it. I wonder what it is all about...... Just did an apt-get dist-upgrade today, after that the problem was there.

Timing is the likely issue, since the wrapper does not change anything else really.
Sometimes I face this also with iterations on slewing to target. Telescope has not come to rest /still moving but capture already in place.
It would help to introduce a dead time there to not overwhelm certain hardware.

Same here, sometimes I also get star trailing on the first exposure after the solve. It seems capture starts before mount has stabilized.
Some timeout setting would help on this.
