Will this fit digital SLR Olympus 600 camera?
You require a t-adapter specific to your camera. You also need to be careful: the physical dimensions are very tight, and the adapter will only fit a limited range of eyepieces, notably, some of the Meade 4000 series. In particular, the socket that holds the 1.25" barrel of the eyepiece seems to be slightly undersize, so many eyepieces that ought to fit don't!
It will if you have the appropriate T-Ring for your camera.
The threads at the top of the picture screw into one side of your T-Ring. The other side of the T-Ring is made to fit your camera body.
An Adorama rep should be able to advise you on getting an appropriate T-Ring.
Yes, but you will need to buy a T adapter for your camera body for the Mead camera adapter to screw into..
