I have heard about different binoculars with different lens sizes. What is the real deal?

I am not familiar with the term "telescope binoculars." online drugs without a prescription However, you can certainly find binocular sets that range from opera glasses to giant instruments that should be mounted on a pier.

You may be referring to binocular eyepiece adapters. These are prism sets that can be installed like a normal eyepiece in any telescope of a sufficient size to support them. They provide binocular eyepiece locations, instead of the normal single eyepiece. This allows the observer to see the target with both eyes instead of one. It does provide a certain illusion of depth perception, and it is perhaps a little easier on the eyes in terms of fatigue.

Of course, it gets expensive buying two eyepieces of each focal length instead of one. And the accessory is sort of heavy and bulky, so it's not built for small scopes. I have experienced them in an 18 inch Dob, and it was a nice view. Not sure it's worth the expense / trouble, but nice.
