The Dusk/Dawn offsets (Configure KStars/Ekos/Scheduler) work, though I can never remember which way is + vs - for each setting. Check in the scheduler to see what it is currently using at the Twilight checkbox.

Mireia - there is an interacting setting you might have missed. Also in the Ekos/Scheduler settings tab: The 2nd line in Offsets is "Pre-dawn". I do not understand what is the intended purpose, or why the default value is 30minutes. But if you change it to 0 then the times shown for Twilight in the Scheduler itself accurately reflect when a job will start and when it will be stopped for dawn.

Sigh. Guess it was too good to be true.



Back to the plan of installing Windows on the mini-pc. I have no ideas as to why I was able get through nearly 30 hours of testing indoors without a failure.

Just the main camera. The ZWO dew heater sticky-tapes onto the front of the camera body and they supplied the splitter to power the heater off of the same 12v used by the camera.

I wish I had a good physical explanation (intermittent open? cheapo thin-gauge internal wire causing a voltage drop?). I won't be 100% convinced for a while yet. With the sometimes 6-hour wait before a failure, even 20 hours of good behavior could just be luck.

After some 5 weeks of testing and just living with the periodic timeout errors, I *think* I have solved it. Always tricky to declare an intermittent problem solved when it often does not occur until 6+ hours into an imaging session, but I am cautiously optimistic.

The problem? This 12v splitter:



It came with the ZWO add-on dew heater that I bought because the internal window heater in the RisingCam was not sufficient on particularly humid nights. I have run at least 20 hours of testing with a different 12v splitter with no crashes or timeouts.

Cool - thanks. The file system was filled with images (as Lights, though the lens cap is on). I was indoors, continuously collecting images to see if the toupcam driver would crash or not. (I *may* have sorted out my problem with toupcam timeouts, but I will post that in my other thread once I am more confident)

I am trying out different configurations to try to learn more about my Toupcam driver timeouts/crashes. With only the Telescope Simulator and the Touptek camera running i ran captures on infinite repeat. I came home from work to see a Ubuntu desktop message about the file system being out of space (not surprising!). The scheduler had aborted, but there were none of the usual messages about the camera driver crashing or timing out.

The last line in the log is "0 StarBlocks freed from StarBlockFactory". Surprisingly, a forum search turns up only a few posts in which that line is also included in the log - but the line itself is not discussed.

So - what is a StarBlock? Is that error related to filling the file system, or does it indicate a driver crash?

Thanks, Steve. I remember glancing at your thread but thinking it was about a dslr issue, so I did not continue reading it. Good to know I don't have an issue that is unique to my installation.

It's not just one fits file, by the way. I get the same error from the Scheduler for any fits file I have tried, including one that I have previously used many times in that capacity.

Yes, it opens in fitsviewer. And also is successfully plate solved in the Align tab.
