These weren't timed exposures - they were literally taken through the eyepiece as a snap (which is a projection picture) - all I did was make up a little piece of wood with a hole in it that fitted over the lenses to hold them lined up and an elastic band to hold it in place - cost - ten minutes of my time to make with a hole saw in a drill.
Set the camera to infinity and snap away, adjusting whatever you can adjust to give you a better shot. The exposures were about 1/30 sec
to 2 seconds (for Saturn which I haven't posted because they're not that good) Increasing the zoom will eliminate vignetting and also diffuse light which may result in over exposure - so if it is too bright and there are no other adjustments, increase the zoom onthe camera !! or fit a filter
