Thank you. I tried it as a comet. It still does not work, but I hope I will somehow solve it today. Pixinsight has quite a problem to get rid of the Mars when it is trying to do it with 91 frames. Should I maybe try less images? It seems thart result is better when I use very low value in Image integration -> Pixel rejection( 2) -> sigma high (I set it below 1) when trying to stack Mars as a comet after comet alignment - but there are still some artifacts which stayed after bright stars and nebulae in the Pleiades, but it is manageable I think. What is worse is that I do not have good results from stacked picture of stars without the mars. I have there and an artifacts around the stars and I have there an odd red shape instead of Mars... Any ideas how to set values in image integration properly when stacking Image which was substracted from the frame of a comet (comet alignment -> substraction and as a file I use stacked Mars without stars)? Or any other tip what I do badly in process?
