Bear with me, I am here to complain! This whole year I had nothing but bad weather and equipment issues. I think having the telescope permanently setup in an observatory has a couple of downsides, I think the temperature fluctuations is causing some of my issues, first it was the Mach1 with a loosen RA, very little, just enough to cause chaos in the whole system, because of it I was not able to calibrate for guiding, tracking was awful, this took months to troubleshoot and fix. Then was my flats, I could not calibrate my images, I don't even remember what was causing this but I also think it was something loosen in the rig. Now a few weeks ago I noticed my images had a huge pattern of dust donuts which I thought were caused by condensation+dirt on the inside of the corrector plate. I removed the secondary to try to stick my hand in there and blow the dust and that's when I noticed the whole ring that holds the secondary in place was loosen and rotating freely and this caused the metal particles to drop on the inside of my corrector plate, this shouldn't be happening, I never remove my secondary, I don't even own a Hyperstar for my Edge 11". Anyway, I was able to make things tight again and place the secondary aligned with the 3 o'clock position so that's fine and I was able to confirm that my stars are round but I can still not calibrate my images and now I have no idea what is going on, things are tights and shouldn't be moving anymore, I'm completely lost.
Now the most aggravating issue, SGP keeps locking up in the middle of the night, every single time, no error message, no indication that it is frozen, things look normal until I check and see that nothing is happening and when that happens, the only solution is to reboot the whole computer, just closing SGP is not enough. Yes I know I can send the log to the guys on the SGP forum but first I like solving things on my own and trying to find out if anyone else has similar issues. If I am able to fix those 2 very annoying issues (my flats and SGP crashing) and I will be back in business.
So, any thoughts? Thank you for letting me vent, I just want to enjoy my hobby and best time of the year for it will soon be here and I would like to solve these issues ASAP.
Please see attached pics, single exposure and stack to see what I'm talking about when I say I have a bazillion dust donuts. Do you all think I cannot calibrate my images because there is something still moving on my imaging train or the dust motes are so excessive that the flats are not correcting?
