This is 30 x 20 sec exposures at ISO 1600 f4.0 using my Canon 60D with the nifty 50 attached (no calibration) and just a little post processing in PS. I mounted the camera on a tripod, pointed it at Cygnus and took a sample shot to use as a custom white balance then let her go. The camera had the EOS Clip LP filter attached.
Needs some work:
