Thanks a lot, that'd be a really nice feature to have.
Do you plan to add also support for LZ4-HC and byte swapping?
last time I used my equipment (Oct 2021), everything worked fine. Guiding was very good, as it had always been (tot rm ~0.5).
Then I had to send my imaging scope away for repair, so I did nothing up until Feb 2022. I took everything out again (I setup and teardown every night) to do a test session and, while focus, imaging, aligning, etc worked super fine, guiding was a nightmare.
The tot RMS was constantly > 0.7, with peaks to 1.3. I thought I did something wrong, so I called it a day and stopped the session.
Then yesterday night I went out for another test session. This time I did everything perfectly (very good PA, mount 3D balanced), but the guiding results were awful again. It's was like guiding was unstable, tot RMS went from 0.6 to 2.5 even though outside there was no wind (my mount is partially protected from wind though) or animals that could have caused that. I tried playing around with some parameters, but they didn't help much (probably because I don't know how to tune them).
* iOptron CEM70
* ASI290MM mini
* APM 50mm f/4.1 guide scope
* QHY268M + TecnoSky AG70 for imaging
* exp time 2.5-4s, then settled to 3s
* remove DEC backlash enabled
* Reset Guide calibration after each slew enabled
* pulse 1000
* max iters 3
* max move (px) 15
* two axis enabled
* gpg ra guider enabled and set to 348
* aggress 0.75/0.75 (I played with those values, some times it got better with 0.5/0.5)
* PEC is disabled
* Kstars 3.5.7-stable and INDI 1.9.4-stable on openSUSE
I honestly don't know what to do to improves things. I've tried PA with iPolar + EKOS, only EKOS, only iPolar. I've tried 3D balanced, a bit unbalanced, but couldn't get the very good guiding I had last year and suggestions/tips for me?
I posted there what happened and why it's no longer working
I also own a QHY268M, and everything is working fine here. I'm using INDI 1.9.2 and Kstars 3.5.5 on openSUSE Leap 15.3.
I've set it to -5C (inside +20) and power went to +100%, and now that is has reached temperature, it's stable at +45.
I feel you! I switched from RPi4 4b 4GB to a 240 USD mini PC and the difference is astonishing. I no longer have "weird" crashed (e.g. with gphoto) every now and then that, I think, were related to RPi slowness.
The only regret I have is that now I'll never be able to use the StellarmateOS app! But I favor stability over everything else
I'm interested in mean ADU only for light frames. I usually keep track of how it changes during the night. Thanks!
Cool, thank you very much!
Would it be possible to add also the mean ADU in #3?
nice work, thanks a lot for sharing it
Yep, I have a CEM70 and it does that (although not always).
No big issue for me because I setup and tear down every night. Might be an issue (or better, an annoyance) for ppl with observatory and stable setup though.
My workflow is: setup everything, staying awake a bit to check that all is working fine, going to bed because meridian flip and auto-park will take care of everything, wake up and see that parking is horizontal (even though I set vertical) and, most of the time, still reporting slewing to. Therefore I click "goto home", turn off everything, etc
