Description

Hi everyone,

today I want to present to you an image of the entire nebula complex around Sadr in Cygnus. This image was taken with the Samyang 135mm f/2 lens at f/2.8. It contains a multitude of nebulae. Some of the more prominent ones: the Gamma-Cygnus-Nebula, the Crescent Nebula and the Propeller Nebula.

Unfortunately I didn't manage to capture a lot of SII and OIII data. Fortunately the skies aren't going anywhere. I really love the cloudy / whispy structures in this area :)

Since I took his image I finally managed to resolve my tilt issues I had with the lens. So the next ones will be even better :) It turns out that before I had rings for the lens / camera combination I bent the threads of my EOS adapter by testing the lens without any support -facepalm- Well I ordered a new one and now everything is properly tilt free.

Thanks for stopping by and taking a look,
Sven
