I have just gotten all the adapters I need for connecting my DSLR to my MAK CASS scope. I now need to ask a question when you put a manual focus older camera lens on your camera you need to set your camera for the max apeture of the lens what settings do you need to do for a scope .
In my experience with a Canon DSLR, forget about aperture value in camera. It's not important. Once you take the lens off and use a telescope the aperture will just read 0. The telescope will be working at what ever it's natural aperture is. Put your camera in Manual mode or Bulb mode and just concentrate on exposure times. If your telescope has a F ration of say F/10 you will need to do much longer exposures than say a F/4.
At present I don't have a guided mount it is just manual so I will be expermenting with the moon so no long exposures until I get my dream mount. I am positive it is a f-10 scope.
My pleasure Warren. Good luck with your moon shots. You probably know already but you need to reduce vibration as much as possible with telescope shots, so make sure you lock up the mirror prior to triggering the exposure (if your camera can do this) and either use a remote shutter release or put a delay on the shutter release (typically 2 or 10 seconds) so your not touching the camera or telescope at all for the exposures.
