Description

This is a 21 minute exposure of the horsehead nebula through the L extreme filter.  I extracted the red channel because I think the horsehead nebula in mono Hydrogen alpha looks amazing. This was a test to see how long I have to expose at f7 with a narrowband filter. I'm shocked that the horsehead nebula appears in just a 180 second exposure at f7. From what I see narrowband exposure times are usually 300 seconds or more so it's nice to know that with a narrowband filter I don't have to expose longer than what I already do.
