10 inch Newtonian on HEQ5 mount
A = 10" = 254mm
f = 48" = 1200mm
focal ratio = f / 4.8
Camera attached with T-mount adapter (Canon fitting)
T-mount rings are available for a few pounds from a telescope supplier. Make sure you get the version for your camera's lens fitting. I will show later how to fit non-SLR cameras.
This telescope was used for the photos you are about to see. It is not as expensive as you might think. The total cost of all of the kit you see here apart from the camera body was only half as much as the camera body. (Or, the camera body was 2/3 of the total cost.)
