So much detail in there, cool pic!
Also, I personally want to fight Alnitak
1) great result, congrats!
2) any advice on the bright star in the middle of the frame? I shot this with my optolong ultimate narrowband filter and star removal didnt recognize this as a star no matter what i did.
Wow that is beautiful!
