I think I'm having calibration frame problems. I will explain what I do and see if I'm doing something wrong. This is an image of light frames 15x300s, Darks 20X300s, Dark Flats 40X.07996 Flats 40X.07996. Integrated in pi and hdr toning in ps. Then resized in windows photo viewer for this forum.
Ok So I used N.I.N.A. for light frames I think this is why id did not frame right I have been having so,e problems with plate solving in nina. After the lights were taken. I took a white tee shirt and placed it over my dew shield and used a rubber band to keep it there and pulled all wrinkles out. Then set up my light panel right on the dew shield and used apt and opened up ccd flats wizard and let it do its thing, when it uploaded to the camera I shot my flats, Then I pulled my camera off the hyper star and placed the camera lens on and put it in a box. I shot my dark flats the same exposure as my flats both took 40 frames. Then shot my dark frames with the camera still in the box. It looks like I have some color differation on the top right and bottom left corner of my frames. I used pi to integrate my darks and dark flats using the pi book. Then used these frames to calibrate my flat frames. Then integrated my flat frames with pi. Next I calibrated my lights with the dark flats, Darks and flat frames. Did a debrayer, and star aligned then lastly I integrated my aligned frames.
