Hi guys,

I'm processing an HDR image of orion that I have taken and I'm having issues with my dark frames but only with the 5 second images. The dark frame totally ruins the image and I'm not sure why. I have attached auto stretched JPG files of the images to see what you think (original 5sec sub, dark subtracted 5sec sub, & 40x stack of 5sec dark frames).

I have tried everythink i can think to do. Just dark subtraction, just bias subtraction, bias & dark subtraction, but they all get the same result.

Thanks, Tim
