 A DSLR with an interchangeable 

lens can be connected directly to the T-2 
thread via a T-2 ring.

flash shoe may bump against the Herschel 
prism. In rare cases, another short T-2 exten-
sion (or a quick release) is necessary.

5.  With a T-2 quick-change system (

# 2456322

 

or

, overall length 15 mm), a bino 

viewer can be connected directly, or other 
accessories such as camers and eyepiece 
clamps can be quickly exchanged or aligned.
