Orion Nebula in [SII], Ha and [OIII]

by Richard Crisp

conditions were clear and cold last night and very moony. seeing wasn't bad but wasn't great either. I had a bit of dew here and there so I guess the transparency may have been affected somewhat in the earlier part of the evening.

when I got up this morning this is what I found in the hopper:
