Description

My first attempt at a widefield image of this region, mainly a short test of the Rokinon 135mm in combination with the Astronomik UV-IR Block L-2 clip filter. The filter solved the problem of red star halos, which I was getting in previous images. Thanks to Nico Carver for doing the testing and providing the information on this: https://www.nebulaphotos.com/reviews/canon-eos-ra/

Description: Lots of changes in this version. Realizing I stretched the original versions way too much, I reprocessed from scratch, keeping in mind I only had less than 1.5 hrs of data. Cropped out Barnard's Loop, I don't think I had enough data for that to add anything to the image. I think the framing without it looks better by highlighting the two main nebula regions.
