Not my best image, or processing, but on alnitak you can see all that "stuff" and its really getting on my nerves, this was shot with my sv48p 90mm (probably the problem) and a Canon 700d, this image was shot on a stock camera, but since this image, I have modified it. This issue really makes me not want to image targets like this with bright stars.
