Hi everyone,
My 450D appears to have quite a number of persistent hot pixels which show as "red" points on my lights and darks.
How would I go about removing them from the image?
Say I align and stack 5 light frames. Because of the alignment, each hot pixel actually creates 4 or 5 points on the image. As my darks are stacked on the same co-ordinates (0,0) it can't remove the hot pixel. It's like I need to align my darks to each of the individual flats. Would that be right?
I'm currently using DeepSkyStacker.
Thanks,
Af.
