Thanks @jasem, I think you are right in your theory. Below are my findings that match yours. The question is when we can get this update (when losing guide star go to plate solving and restart guiding)?
I was not attending EKOS when this happened with the images from 20-25 as given by example, but I have seen the guide totally stop and resume again trying to find a guide star. To be sure, I have attached the log file generated and clipped it only to the events between generation of img020 till img025.
Hi jasem, no, I didn’t abort the guiding. Just checking every now and then, and found the target off center FOV.

I was going to suggest performing plate-solving when the guiding star is lost for more than 2-3 frames. IMO adding plate solving to the beginning of the job is not going to solve this problem, as it happens AFTER the job is already started and in progress (in the above example it happened from img20 to img25), and plate-solving EACH captured frame is so resource-intensive.
@Jasem
I don't understand this behavior of the internal guider (IG). I believe what is happening is that the IG was tracking the guide star, then lose it for a frame or two, then another star pops up from the cloud in the periphery of the captured image, IG search and find this new star and ASSUME it is the same guide star it was tracking and tries to bring it to its original location. If we treat the newly auto found star as a new guide star and just keep guiding based on the new parameters (just trust the mount), I think this will fix many problems. Adding a plate-solving option after losing the guide star will assure accuracy.

Hello,
In the past few weeks, I had little time with clear skies, but I noticed that when a cloud briefly crosses the FOV, the EQMOD mount shifts a little and don't preserve the primary object (in my case was M82) in the center of the FOV. Here is an example...
I found and currently evaluating the "Observatory" application codeobsession.com
It doesn't do the archiving part (I guess everyone just stores somewhere), but it does cataloging and tagging images for future search. I still have difficulty using it, but it is the only one of its kind that I can find (on Mac only)...

for me, the symptom of bad cable was intermittent mount connection. While it is working, INDI loses connection, and when restarting INDI, it worked fine

Hello
Is there is a software or solution out there for archiving the raw FITS and may be processed images? currently, I just zip them and save them on an external HDD...

It happened to me before and it was the EQMod cable. After replacing it, the mount stopped acting bizarre...

Hi Daniel
I’m talking about halos all over the picture… stars expected to be big at f/10. Temperature can drop at night below 0C but I have the dew heater on. Do you maximize the dew heater level at winter?
PS this is my 1st time to capture in this weather

Hello
The attached image is a staked raw capture for M_34. I noticed many hallos in the image. I think post-processing can take it out, but any idea what caused it?
No, it is my all-sky cam. My weather station is still WIP. didn't get enough free time lately

Hi Max, It is my DIY Allsky camera
Its public link is allskycam.mhammady.info/01/
It helps me in planning (and weather)
