More magnification with DSLR's was created by John D
Hi guys,
I have a question I've been meaning to ask but never got round to it. I want to get more magnification out of my Nikon D80 but don't know how to get it. I am wondering how ye do it, should I use a barlow lens or just zoom in after the image is taken or anything like this?
Any advice appreciated

Hi John,
I know it might sound obvious, but I have to ask, do you mean exclusively at the eyepiece? If so, instead of just prime focus, you can get a camera-eyepiece adapter, whereby your eyepiece acts as the lens for your camera. There are those out there that are camera specific i.e. the reticle of the eyepiece is the correct +/- distance from the camera sensor, then all you do is focus with the focuser. I have seen one, but I've never used one (on a Canon). They often accommodate 2 eyepieces at right-angles t each other - you focus with your eye in one, then flip the mirror to let the other one go to your camera.
A search on the web might yield better results than me!
Hope this helps.
Seanie.

Prime focus not working with your camera John? How's that?

The focuser doesnt move out enough for even the smallest eyepiece, I had to send back the camera adapter.

That's unusual, sounds like the secondary mirror/focus hole/focuser were brought in closer than should have been. A bad flaw in design. A scope fault, not a camera fault John. What telescope was it?
