This is my take of the area around Antares from a light polluted outer Melbourne suburb just the other night. It was a window of opportunity between cloudy nights and I was actually testing out this Sigma 35mm f1.4 prime lens.
I'm not overly impressed with it's quality for Astro work due to some chronic astigmatism issues which meant a severe crop was necessary to remove the worst areas. It's a nice portrait lens because it's central area is really the only usable part of the image and at f1.4 the surrounding areas are so out of focus that it's of no concern.
Even stopping down to f4, as was the case with this shot, didn't help much. This is the result of a combination of 15 x 90sec UVIR and 8 x 150sec CLS filtered shots at 800 iso with the modded Canon 550 mounted on a Sightron Nano Tracker.
