Hy,

Many thanks for this information and the link.
I guess I have to spend some time to get a deeper understanding of SEP and the meaning of the different models and parameters.

I'm trying to understand the meaning of the sky parameter in the EKOS analysis module. I guess it could be mag/arcsec^2 but sometimes I got some doubts. Are there any information available how this parameter is calculated without digging into the sources?

Many thanks.

Arnold Graf created a new topic ' ASI-EAF driver issue' in the forum. 3 months ago

When I use my ASI EAF focuser with INDI the focuser value "absolute position" is decreasing with each movement of the focuser regardless of the movement direction. As soon as the value "zero" is reached no movement is possible without new initialisation of the absolute position. I guess that is not intended.

To my knowledge this feature is under test and shall be incorporated in version 3.5.2 of kstars.
See "indilib.org/forum/general/8602-new-polar...me-and-features.html" to follow discussion.

If I check the "Local Sidereal Time" in the EQMOD TAP "Site Management" it seems to be different from other sources with same input data. "Julian Date", "UTC" and "Longitude" seems to be correct but "Local Sidereal Time" shows a deviation of "2x impact of Longitude". To me it looks like a signature issue of the "Longitude" impact. Could please someone verify my observation?

Integral gain of zero is a good starting point as high integral gain may cause stability problems. Min and max pulse should not be that critical. Good starting points are min=100 ms and max=5000ms.

The impact of symbols is very strong but there are more parameters with impact on binary size (see e.g. interrupt.memfault.com/blog/best-firmware-size-tools).

The different binary code size is most probably caused by the symbols in your code. If you "strip" your binary, it will be close to the "original Stellarmate" size.

Some settings were missing but now it works fine.

Arnold Graf created a new topic ' Dome Slaving' in the forum. 5 months ago

Hi,
I'm trying to learn how Dome Slaving works but I failed to get it work. I use Ekos with simulators for "Dome", "Focuser", "CCD" and "Telescope". Everything woks fine but "Dome" does not follow any motion of the Telescope but stays permanently at 270┬░ even "Slaving" is "Enabled" and the Telescope is moving.
Any idea what is going wrong?

Arnold Graf replied to the topic 'Drift Plot of Guide Module' in the forum. 5 months ago

I'm sure you are right. When I made these series I had a significant PAE (26') because they were part of test cases to challenge a bit the guiding capabilities of Ekos. But I was not aware, that the resulting image rotation could not be fully compensated by OAG guiding.

But next time I will be ware.
Many thanks again!

Many thanks for the comprehensive explanations and hints. My question came up when I detected bad pixel traces in a stacked picture even though the Drift Plot looked ok.
As I use OAG guiding it is hard to imagine that there is a major relative movement between the main camera and the guide camera.
Any idea about the root cause of such bad pixel traces?
