Hi everyone!

I am complete novice working on a kstars ekos setup using a star discovery mount, a canon t3i and a newtonian all connected to a rock pi. Here follows some confused questions.

One problem I have is that I seem to have two places where I can set my focal length, in the mount tab and in the gphoto tab. Moreover, when I set the focal length in the gphoto tab and save, it still reverts to focal length 300 aparture 50 everytime I restart. Otherwise I have no problems saving changes I make in those tabs.

I also have focal length settings in the align tab. However, they seem to always be set to 300/50 regardless of what I set in the mount and gphoto tab. So basically, my question is where am I supposed to input my aparture and focal length for the align module to get the right settings?

Another problem I had tonight trying to capture and solve was crashes due to segmentation fault and sometimes to many files open. I fixed one, many files related error, by turning of sound, but it was not enough to get away from the many files error altogether. Any thoughts on that?

Also, when using astrometry.net locally must I have astrometry added as an aux in my indi profile, or does ekos handle that for me automatically?

In the slightly older version of ekos that’s on my astroberry (3.6.0 I think) I setup my various lenses/telescopes in the devices menu in kstars (the outer ‘layer’ of kstars/ekos) I then reference the appropriate entry in the profile in ekos. The align module starts off with these focal lengths but may tweak them if it platesolves and finds they should be different. I usually then take note of this and update the entry in the devices menu so that I start off with the correct value next time. I use the sony version of the gphoto driver and don’t set it there, it just automagically gets set from the profile afaik.

Newer versions of kstar have a new way of setting things up I believe so someone else will need to advise you if this doesn’t help..

Hi Magnus,

To Nigel's point, if you could let us know what version of KStars/EKOS you are running I'm sure the members can help you out. The recent version of EKOS has implemented optical trains which handle some of these things.

Fred

I am running version 3.6.2 stable

Magnus - since you are running 3.6.2, have you looked at your settings in Optical Trains to see if there are any clues there?

Thank you Fred!

I found the optical train menu and managed to set the correct scope. Still somewhat confused about what the focal length settings in the mount and gphoto do, but I guess it doesn't matter. Unfortunately, it has been cloudy for a number of days so I haven't had a chance to work on my astrometry issues yet.

best,
Magnus

Good Luck Magnus! I think the Optical Train scheme is a good one but it can be a bit unclear given there are other places in EKOS/INDI where duplicative information can be entered and which has priority.
