When I stack my light frames in DSS, the borders of the image are completely black /or in a completely different tone than the rest of the image. It's not like it happens just a bit, it covers an important part of the image, enough to spoil parts of the nebula. I didn't had this problem at the beginning, bit know is something that always happens when I stack. Please help
Stacking error in deep sky stacker
DSS tries to use as many of the frames you register as possible. Unless they overlap perfectly you'll get areas of lower S/N around the edge. Try to make sure all your frames overlap properly. If you stack in intersection mode you'll get a pretty good idea of the extent of your overlap.
Well written Helpful Concise
Post above is excellent.
Did you plate solve your target for each of the nights? If not, you may have field rotation and it is normal that you could have a border.
solution, crop it out.
review individual light frames, and see if you stack a alien image, alien=something that should not be in the stack
If you leave the border, you may be able to process the noise, but you will introduce other issues.
1- stack with intersection in dss
2- crop image border
3- wipe image of lp
4- develop strech histogram
5- process as usual

Removing the fixed-pattern background from GSENSE4040-based camera images
INTRODUCTION This post presents a calibration strategy that removes virtually all of the fixed-pattern background in most deep-sky images taken with GSENSE4040-based cameras. This chip has a so-called scientific CMOS (sCMOS) architecture, which provi...
Dark/flat frame calibration issues may cause border artifacts during stacking.
Dark, Flat and Bias Frames on Sigma 100-400 DG DN OS for DSO
Hello People, I know this have been asked before here and is widely talked about over the web however I am little confused with the information I have come across so posting it here for more clarity. I have a Sony A7III w/ Sigma 100-400 DG DN OS lens...
Proper calibration frames prevent stacking artifacts like black borders.
Cosmic Rays on DSLR images?
Hello, Recently, I noticed on my DSLR images artifacts like shown on the picture. The position is always different, and colours vary. Could be a dead pixel stretched in Deepsky Stacker. Cosmic Rays? Just curious Thanks and Cheers Robert
