The BJP is still going as far as I know. It used to be very commercial but I think they've gone a bit more studenty these days.
missed this comment the first time around... interesting..It's an infrared filter on an unconverted Canon 5D. It works well but the exposures are long, about 10 minutes for that one.
Really? I was a bit concerned that the noise handling might not have been up to the job with it being an older camera..Well I was very impressed with the noise handling for the Aurora shots...
Any chance of a copy of the original RAW file? - I'd like to run it through the software I use (Phase One C1 SE) to see how the noise reduction compares on the same area100%
