Description

The Cave Nebula is situated after a long road of acquistion and processing, on the left : ). It probably needs better skies than Bortle 8, given that it is a very faint object, so it gave me a lot of headache. The oxygen was really difficult to emphasize even with some extra hours and gain increase to 200.
