Individual frames look fine, but integrated image is all green
I'm not understanding what's up with my integrated image. It ends up all green. The individual frames, after normalization, look fine (I've attached one). But the integrated image looks all green (attached also). I'm using a ASI533MC and an Optolong L-Pro filter. In tab 0, I chose RGGB pattern, Adaptive Airy Disc for algorithm, and checked the force Bayer/X-Trans CFA box. I'm using the defaults for the other tabs. What am I doing wrong?
@mfschmitz There are strange bands to the top and bottom of the integrated result that indicate an issue with some of the calibration frames. How does the integration result look when you don’t use flats?
@wvreeven Here is the integration without any flats. Just darks and lights.
@mfschmitz There barely is any difference between the two images, apart from the fact that the upper left and lower right corners suddenly have become purple. What result do you get it you simply integrate the images without any calibration files at all?
@wvreeven Ah Ha! That made a difference. Integration from just the lights attached.
@mfschmitz How did you take the darks? Were they the same exposure time, temperature, gain and offset as the lights? And taken with the same software as the lights?
@wvreeven It's the darks! Here is the integrated image using lights, flats and dark flats. Looks much better. I guess I'll be making some new darks -- the ones I was using are only a couple of months old.
Thanks for your help.
@wvreeven The old darks were all the same temperature, gain and exposure time. Not really sure why they made the problem, but I'll take some new ones and see how that goes.
