Today I got myself an adaptor that allows me to attach my old Vivitar 500mm f/8 lens from my 35mm SLR to my Nikon D40. I also got myself at adaptor to allow me to fit the camera to my 4 inch refractor telescope.
The main image is taken with the Nikon 18-55mm lens and gives you an approximation of what the eye sees. Bottom right is an inset of the view as seen by the Vivitar and bottom right the telescope. All three images have not been cropped; I just scaled the inserts to make them fit. All three images are centred on the same TV aerial.
If you’re thinking that the telescope image is blurry then you’d be right. I noticed that the movement of the mirror in the dSLR was enough to induce a little shake into the telescope. I’ll have to look into this and find a way of securing the whole rig.
