I regularly use PixInsight for processing my data and have come to rely on the versatility. The batch preprocessing feature for example, it comes in handy at when I am pressed for time and just want a quick and dirty view of a set of data but otherwise I am not a huge fan of using that script.
My scope is set up in a shed in my back yard, it's relatively easy for me to collect data. I never move the DSLR unless I absolutely have to, I may only need to take new flat frames a few times a year which makes life so much easier. This means I don't need to put my DSLR in the refrigerator to take dark frames anymore.
How do I deal with temperature changes in my data? Is there a way to get Pixinsight to match and calibrate light frames with the corresponding matching dark frames automatically?
The problem I am running into is I am inundated with data that I can't easily reconcile. I might have 100+ light frames of any given object that may vary in temperature by up to 15 degrees C. This makes pre-processing a bit challenging. Of those hundred light frames there may be a few clusters of data within a degree or two of each other but the range is rather large. For example for the Iris Nebula, I have 23 lights at 29C, 7 lights at 27C, 28 lights at 26C, 6 lights at 25C, 14 lights at 22C, 16 lights at 21C 17 lights at 20C 13 lights at 16C, and 7 lights at 15C.
I have a dark library that loosely corresponds to those temperatures but it doesn't correlate perfectly, however, I am always adding to it. Someone please tell me I don't have to calibrate this data with the same flat's and bias frames 9 different times. I don't know if I have the exact darks for all those frames.
Please don't tell me the answer is a dedicated temperature controlled camera, my wife will not understand.
I hope someone out there tells me, hey dummy you over looked this feature...try this...
