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

Hello Robert,
Is this an integrated (stacked) image or a single frame?
This is what I get when I stack images with hot/cold/stuck pixels without using any outlier rejection method.

Hello Diva!
It is the stacked image.
I just found the single RAW frames showing a violet dot near the same location on the image.
Looks pretty much like what you got. Too bad, I won't make history discovering cosmic rays 
I never noticed this before. After all, the DSLR is almost a year old while I am living a subtropical region.
BTW, you are not at all "launisch", but kind to reply and help.
Thanks a ton and Cheers
Robert
