Hi,

 

I have been using APP with great succes for a couple of months until I started to notice these pretty bright lines of noise in my images. I made these go away with creating a new BPM with a kappa high of 2.0. Now I have a different problem. I have these colored noise lines showing around the stars. Think I tried all possible combinations of stacking to get rid of them and getting a bit desperate about it:P

example in screenshot below. Can anybody help me with these?

Ok so I used my old BPM and the star artefact problem is exchanged for the (hot) noise lines again. Wierd thing is I never had this noise before last week with the same calibration frames.
