I am trying to combine two images using PM to add a comet to star field (having followed the procedure for comet processing as per Keller...).
I am quite happy with the comet and star pictures per se, but when I combine them I lose a lot of the stars.
I have used the formula C + S (ie just adding the two files - C= comet, S= stars) I have also tried C + (2*S) to see if the latter would give me more stars, but without success.
Attached are screenshots. "masters" shows the comet and the star field to be combined. "combined" is the result, which seems to have killed off a lot of the stars.
TIA for any input
