DSS trashing my stars

300% crop of a sub before stacking

Been tearing my hair out all evening trying to work out what is going wrong.

Any thoughts?

Seems to be some function of 'automaticaly detect & replace hot pixels'. It might be confusing small stars with hot pixels?

You can get that effect if the target is not in focus, OR check to see if cosmetic tab is asked to detect hot and cold pixels.  If the detection threshold is more than 1 pixel it can sometimes do this to the stars.  I suspect it is the latter.

Was set to 2 pixels.

Did you try it again and did it work?  

I had the same problem at one time until some kind soul on a forum made this suggestion.  I changed the setting and not had a problem since.

Music to my ears thank you - this has been happening to me and very evident when I try and make a separate star layer! Thanks to OP for posting!

I reset the threshold back to 1 pixel and it seems okay. Trouble is I don't even remember changing this parameter!

Glad it worked.
