Although the standard Canon EOS 60D DSLR camera has a long-wavelength filter that does not transmit as much hydrogen-alpha light as a 60Da, it is still possible to shoot red emission nebulae with the 60D. A reasonably dark location and a special filter, in this case the Astronomik CLS filter, can be used with longer exposures to produce good results with brighter hydrogen-alpha emission nebulae. The North America Nebula was shot unfiltered (left) and with the CLS filter (right).
