Description

These are some iconic but quite faint nebulae in Orion. The data caught with the IDAS NBZ filter (Ha+Oiii) reveals a sea of Ha emission in this area. I caught the big picture with my Samyang 135 the other night and added 50% data to NGC1788 from the RASA caught the same night. I then added Canon 300 data as luminance to the Witch Head collected when I was down on Lizard Island way out on the Great Barrier Reef some years ago - a place where the sky is as dark as it can get.
