Elephant's Trunk Nebula (IC 1396)

The oxygen shot was ruined by incoming clouds. As a result, at least a third of the 12 frames taken could easily be sent to the trash. I didn't, I stacked them anyway. And, honestly, I was a bit shocked by the result. After all, the nebula is not the brightest, and the oxygen on single frames was barely visible at all. So I decided to post it, although I will definitely shoot again.
