Still learning unique challenges using Celestron C9.25 Edge @F10, monochrome work, and PixInsight. Had to crop LRGB aggressively do to alignment issues and when shot colors during night. Did Lum (3/19/23) and RGB (4/13/23). Was able to troubleshoot strange star issues I had observed shooting M81 Bode. Still don't understand why dew heater was causing a spike or line to be drawn through stars - but if I get the power down - it goes away. Need to now determine why I am getting spots. Had to drop the color a bit to stop red blob from becoming too visible. Best guess is maybe finger oil on "Lum" and "R" and perhaps camera sensor? Any tips on Pixsight or imaging are welcome !

Could you send the data over? I could probably give better help if I could have a look!
Hello - I uploaded the raw uncropped PixInsight (.XISF) to my GoogleDrive. (G) https://drive.google.com/file/d/1KG8C4GF1I5E4Ydsf082SppFQiS7VUNwy/view?usp=share_link , (L) https://drive.google.com/file/d/1SJQpAveiifX5BAxTNS_x63zREhfQI-x_/view?usp=share_link , (R) https://drive.google.com/file/d/1Ds-EhKP8kWW1XhKOdoaZFWSyTpv5SRYn/view?usp=share_link, (B) https://drive.google.com/file/d/1o_vVTqTROmqkf61RfGoyqhGqpH_9oNb1/view?usp=share_link, (My Edited Copy-.XISF) https://drive.google.com/file/d/1OAB1mIaJor-sn27XLS1tWyGC8G4fm0Kr/view?usp=share_link . Thankyou for offering to look at the data. I will try to reshoot these later next week to better align the luminance / color. While we do need some rain - I think we are largely going to just get clouds for next few days. Let me know if you concur on the finger smug / foreign matter making the blobs. My guess is either pollen or wood ash worked its way in to the filter wheel. I know some got in under the corrector plate as well. I think thats doing it as they kinda look like an unfocused star pattern when one is trying to test collimation. Edited - Also adding my Edit from PixInsight AutoCrop. The overexpressing the color hides the red blob a bit - but the autocrop was a bit aggressive... https://drive.google.com/file/d/1n3Pfm2iw_MGAvLtXEtnKUJS96yD_GZlQ/view?usp=share_link .
