I struggled for several nights last year in a futile attempt to take photos of the Crescent Nebula, NGC 6888. This emission nebula is about 5,000 light years away, and between us and it is a lot of stars. It wasn’t until I got my Optolong l-eXtreme filter that I’ve been able to see the nebula properly.
Milky Way season is upon us. Get out and enjoy the view!
