It's called the frog mouth nebula. Something you have to live with is schmidt reflections on very bright stars (Alnitak) in this case. It has something to do with the profile of the corrector I think. Good thing is you can get rid of them very easily by offsetting and stacking as they move when you move the scope and the subs are so easy to get I never had an issue with them. Funny enough there's none in NB. Don't know why.
