Internal reflections

Roy Hansen

In my 4 years of imaging I’ve never had any internal reflections on my images. Last week I was imaging Sh2-249. There’s a bright star and it looks like it caused reflections from the star. On the very left of the image a large one. I can crop that out but just to the right of the star 2 little ones. This is on my Ha master. The Olll has a smaller one on the far left no small ones next to the star.  The Sll has only small one next to the star. What can I use to remove these. Selective rejection won’t work since it’s on all subs

Hmm... you can get close with the other substitution method I showed...

(it is also available for free on YouTube... )

But this isn't perfect for you since there is a little overlap between the reflections and filters. Watch my video to see if it gives you some ideas.
