Hi!

I currently use Ubuntu as the basis-distribution on my RPI to control my observatory. Would it make sense to switch to Stellarmate OS instead of ubuntu, and modify it as needed in my setup? Or would that possibly break something, prevent updates to install and so on... I could see the benefit of having the SM android app available, which I think is not possible on Ubuntu, and no need to mess with setting up a VNC server on a fresh install.

Best Regards,
Søren

A 'simpel' levels with histogram is very convenient for adjusting the stacked image.

Hello!

Tried again and noticed that the mount model may have been completely wrong, as the slews were nowhere near the target. Of course plate solving would eventually get the mount to the right place.

I purged the mount model and it seemed to work ok for some time. Gotos were quite good initially, but then they seemed to become worse and eventually it would never reach is destination. It would plate solve fine and get a solution, but the corrections done were really small and did almost not move the mount, even though it was 5000" off, and even after 10 solves it had moved almost nowhere. After this I was frozen and gave up for the evening.....

Then I found this:

When using plate solving to refine every slew position it is best to not use the N-Star alignment....

from

indilib.org/devices/mounts/eqmod.html

Could N-star alignment be the thing that seems to
(gradually) ruin my mount model?

Thanks all, you certainly convinced me to get stellarmate os!

Hi!

Just noticed that one can buy stellarmate os. I dont really need it, but I was wondering if buying stellarmate os would actually financially support the development of Indi and kstars? Or is stellarmate os sold by a third party not really affiliated with the development of Indi and kstars?

Best regards

Hi again!

One more thing comes to mind.... I have a roll of roof that I control using the dome scripting gateway and some simple scripts I have written to park and unpark (open/close the roof). Could the interaction between the (non-existing) dome and the eqmod driver play any part in this?

That position does not work in my observatory, so I initially started out as you said (pointing near Polaris), did some go-tos and plate solves (some failed, others did not), moved the scope using the mount control panel keys to the position that allows the roof to close and choose use current position af park position. Maybe this is the wrong procedure to use a custom park position?

Thanks for the suggestions.

It happens when I select the first target right after selecting "unpark". The park position is with the counter weight almost horizontal and the scope pointing slightly into the ground on the dec axis.

kstars and indi are running on the same RPI 3 and kstars 'LT' in the top left corner matches the system time and the local time. UTC time under EQ mod also matches what google says UTC time is.

Target pier side is set to "auto". I will try to force it next time to a manual setting just to see what it does. May take some time before it stops raining, though....

Should I try to purge the mount model? Maybe it is way off somehow?

Hi!

I use an eq6 mount with the eqmod driver . Go-to and plate solve now seems ok. But the scope (Newton) is in many cases hitting the pier. For example, I park the scope on the west pier side. If I then unpark and go-to an object quite high in the sky but west of the meridian, the scope will stay on the west side and possibly hit the pier. The counter weight shaft is in this case pointing a bit up. Shouldn't the mount move the scope to the east side in this case?
Could eqmod somehow think the mount is already on the east side? If yes, how do I tell it that it is not?

Best regards

Here is what is happening in my case: kstars uses the scale information found in the fits file to generate the options, over writing anything I manually set in the options dialogue. It seems to be done in Align::startSolving in align.cpp where getSolverOptionsFromFITS is called. The scaled reported in the log matches exactly 0.9 and 1.1 time the pixel scale in the fits header and clearing FOCALLEN and SCALE in the fits header results in a correct solve (but without any scale information...). Maybe there should be an options to either use the fits header (if available) or always use the user set options? My fits header was containing (slightly) wrong information leading to the (slightly) wrong image scale being used and there seems to be no way to manually overwrite this from ekos....

Great to know. It also makes sense, as one thing that was changed in the RPI 4 was the USB controller. I will keep my ASIs and they them when Ubuntu is ready for the 4.

Ah, thanks. It must be the same as I have already tried. I was hoping that someone had modified it, such that it would actually work :-)
