Photographers who are engaged in astrophotography today are in luck, Canon has thought of them and throw the market the new EOS 60Da, a digital SLR camera designed specifically for them. It is the replacement for the EOS 20Da, and this new model, of course, is based on the specifications of the EOS 60D, the difference is that it incorporates a low pass filter that makes it more sensitive to wavelengths hydrogen alpha (Hα ) of light, designed to capture the bright red colors produced by emissions of the nebulae.
