If the Canon was exposed for 90 seconds, i.e. the time it took to get the RG&B channels out of a Mono camera, then it would have performed better, but that was not the point of the exercise.
I was curious to see how the two cameras would deal with the same amount of (limited) flux, and was admittedly surprised by the obvious differences in signal and noise between the two. |
OK these are taken with my ed80 and a cooled modded canon 350D, please note the ambient air temp was 23 degrees I had the camera cooled to 5 degrees. these are unprocessed suburban images, so there are no darks, no bias's, no flats (and badly polar aligned)
