Description

First light with my new Rokinon 135mm lens. I have very little experience with wide-angle shots (using lenses) - so I have a lot to learn. A couple of things I need to figure out, for starters: why so much vignetting, despite the use of flats? Also, why do the brighter stars have a strange diffraction pattern and artifacts? Most of those issues were cropped out or repaired  - but I need to figure it out. No filters were used.
Despite all that, I'm generally pleased with this as my first attempt at 135mm. At least I picked up some clouds of dust. I'm sure more data would have been beneficial, but with getting a late start, trees got in the way .
The journey continues!

Description: Completely reprocessed this from scratch using a better workflow. I concentrated more on the nebula and stars than the dust, which looked strange in the original image (due to inexperience with the Rokinon lens). Will go for dust next time it comes around.
