Well done Canon (from a micro 4/3 user) for releasing a camera aimed at a small niche market! It is two cameras in one, a normal DSLR, and a camera suitable for astroimaging. However, I'm confused as to how large the increase in red sensitivity will actually be. The press release states that "hydrogen-alpha light sensitivity that is approximately three times higher than that of a normal Canon DSLR camera. This produces a 20-percent higher transmittance of Hydrogen Alpha line". The "silent shooting" feature is also interesting; I wonder how it is implemented? The fully articulated LCD is great for use with telescopes (as is the case with the Panasonic GH2).Can the 60D produce video using just the small central portion of the sensor? That would make it a great camera for imaging the planets too.Most astrophotographers who use DSLRs favour Canon, and many astroimaging software packages have features for PC control of Canon cameras, so this will generate a lot of interest.
