Canon EOS 600D -mod
This is my main camera for astrophotography.
I bought it in summer 2014 only for that purpose and together with Jakob we sent our cameras to UK for modification by removing the rear colour correcting filter. This makes the camera more sensitive to especially red light and the result is more detailed red areas on the night sky and often also shorter exposures. The only catch is that after this modification the camera works quite badly for regular use with a camera lens.
Sensor type: CMOS
Sensor resolution: ~18 MP
