My setup is a Celestron SCT 8 inch with a ZWO EFW-7 and ASI1600mm Pro on a permanent Paramount MX+. I run Voyager though TheSkyX. I’ve ran the sequence fine with my LRGBHaO filters, darks, and bias. However, every time a run my flats (with any filter including the Luminance) I get an error saying something like exposure out of range…saying it will take 235 seconds to get a flat. When I look at the ADU, the most it shows is 255. I’m using the Spike-A flat pannel mounted on a wall in my observatory with its max output. I have the min exp set to 3 sec and the max exp to 10 sec with the Target ADU set to 20,000 with max error up to 20%. Can’t get it to give me any flats because of the errors above. Got any idea if I’m doing something wrong, or do I need to adjust something in TSX, or what? Thanks for the help.
