Hi @hanva,

Thank you for your question and welcome to the APP forum. My apologies for the delay in my response.

If you want to calibrate DSLR data without darks, you will need to use at least a masterbias if you are using flats as well. Are you?

(The hotpixels can be taken care of most efficiently by making a one-time BPM from a simple set of darks.)

Kind regards,

I had a couple of occasions where I had to throw out my bias in order to integrate my hydrogen Alpha Subs. When I included it I got blank frame when I pulled it out of the mix I got it really nice image in hydrogen Alpha

Hi Greg, Probably a case of subtracting the bias pedestal twice then 😉

Next APP version 1.060 will not have that problem anymore...

Great. And yes, I'm sure that's what happened.
