Various BORGs

BORG modular concept gives you the freedom to build up the system whatever you like as long as you can reach the focus. Only restrictions to be considered are vignetting and back focus distance when reducer or flattener is used. Anything else is virtually free. This is completely different from any other conventional telescopes. Let’s see some examples.

1) Double manual focus in combination of crayford and helical

2) Auto-focus

Followings are several different auto-focus systems.

50FL + Modified Minolta lens +Sony Alpha 37 by Kikugin

All look very skillful enough to build AF-BORG systems. And also good technique to use their own optical systems. They look enjoying BORG very much.
