I downloaded the file again and .... the content is now changed (from few days ago) and I can see the ASI120MM-compatible.iic is there now
Interesting they did not change the zip file name
Anyway, I now flashed the firmware and I can now confirm that my 120MM now works and acquires images correctly!!!!
Looking toward good weather now.
Thanks all for your support
I think I got DEC pretty well under control now. Need to work on RA next:
For the most part. That sawtooth pattern is - I think - the result of mechanical tension that builds up as the mount fails to move in DEC until the tension breaks and is released, resulting in the overshoot in the other direction. When you adjust the tension, feel every moving part and determine whether anything snags, has resistance, etc.
Frankly, from looking at the simple construction, I am amazed that the mount can perform as well as it does (most of the time now) for me.
You have to take the DEC cover off, straighten the belt and then tighten it so it has no more than 3 mm slack when you press it down in the middle. Having the proper tension and it running straight is key.
Nonetheless, this remains finicky. For instance, I can now get outstanding DEC guiding with an RMS of 0.5" early in the evening, only to see it fall apart and disintegrate to >1" after the meridian flip. That shows the mechanical limitations of the mount.
You will have to get a feel for how much tension the belt should have and whether the axle is running tight, but without excessive resistance, etc. A real problem IMO is that the DEC motor is drawing about 40% less power than the RA motor, which results in it losing steps whenever there is too much resistance.
Also, make sure that the mount is perfectly balance in DEC and that there is no cable drag. With those weak motor, you have to strive to eliminate any potential mechanical interference.
Hope that helps,
Perhaps a naive question, but how hard would it be to integrate Planetary Imager into Ekos?
That is a dynamite platform for planetary work with monochrome or a OSC camera. Unfortunately, with my feeble Linux skills I have so far not been able to compile it on the Pi4, although it ran on the original Pi3B+.
If that could be integrated into Ekos, it would be a mind-blowing addition to the system.
Thanks, Wouter, but I am confused now.
On Cloudy Nights you write: "....after resetting the alignment model in the CEM25P hand controller and disabling DST (and setting the UTC offset such that it compensates for DST manually), it works like a charm. Pointing using plate solving, meridian flip, parking all work very well."
Does that mean that parking does indeed also work in your hands with the CEM25P, not just for me, and that the problem is isolated to the GEM45?

I know that you don’t and we have already compared our INDI config files which are exactly the same. Apart from that, I am not the only one who has parking issues with a CEM25 or GEM45 and to my best of knowledge there are many more people with issues than without (actually I think you’re the only one without).
FWIW I use the stable release and have had this issue since we started using this mount which is over a year now.

After the purge, reinstallation of Nightly and full upgrade the problem seems to have disappeared. I don't know whether that was the result of an updated file in Nightly or a purge of a misconfigured one, but the system appears to be back to normal.
Thanks to Hy, Peter and Jasem for looking into it.
Hooray, success (I hope)! I reinstalled Kstars and performed a full-upgrade. Now refocusing on filter change seems to work again in Nightly. At least the first change went smoothly as expected.
I am letting it run through the night, will recheck in the morning. Will also check whether this translates to independent builds as well.
I hope that settles it. This has been driving me crazy for the last 10 days or so.

Focus module should also at least run once successfully before all of this, but I presume you already done that?
