Hi all, DSS does a perfect and user-friendly job for what you use it for. I use MaximDL also (and if you use previous calibration files) it is now just as easy...

I agree wholeheartedly with the sentiment, but I'm not sure branching a new forum within DSS is the best solution. I think that many of us are members of other...

Hi Soren, I would think the signal in a dark frame is defined as the stuff that needs to be removed, like the amp glow, hot pixels, and just the build up of...

Hi Søren, ... Oh no, or you wouldn't need to subtract them. There is a dark signal (the part that you want to subtract) and some noise mixed with it. As Simon...

Hi Luc, I think Soren was hinting at 'isn't the SNR zero because the dark is by definition a noise and not a signal, so S/N = 0/N = 0'. (Soren, if I...

Hi Simon, Craig, As long as you don't use flat, you don't really need bias frames (the bias signal is already in the dark frames). But with flat frames, bias...
