Another test image taken with my new Canon T3/1100D modified camera. Comparison of single sub-images taken in November 2011 with my modified Canon XS and the new Canon T3 mod show a lot of improvement - more than 2x the nebulosity and only a quarter of the noise. The pixel size and resolution is also a better match to my imaging setup.
