The deep-sky camera is a Canon 7D on which the stock IR-cut filter has been replaced to allow transmission from 400nm at the edge of the UVs up to 700nm in the infrared. Focusing can still be achieved with regular lenses but all images must be shot RAW in order to be able to remove the reddish tint that corresponds to the new wavelengths of red that it can now see.
The other camera is an off-the-shelf Canon m6, small and light. Shoots video for planetary. Decent for deep-sky, surprisingly low noise at long exposures.
