In brief

It's been a while since the EOS 20Da, which was a digital SLR specifically designed for the needs of astrophotographers. The 60Da offers the same body, 18-megapixel CMOS sensor, Digic 4 image processor and 3-inch articulating screen as the regular EOS 60D. The big difference is that it has a low-pass infrared (IR) cut filter, which allows photographers to better capture hydrogen-alpha light of 656mn.

Plenty of astrophotographers tend to modify their cameras in order to better capture this light by replacing the standard IR filter, which usually filters out the particularly reddish hue from H-alpha objects. The 60Da also has a maximum ISO rating of 6400, which is expandable up to 12,800, and Canon has thoughtfully included a remote controller adapter (RA-E3).

The 60Da will be available as body only from 19 April 2012, though no local RRP has been announced.
