2"/2" Inverter Ring Application example

Short information (and GIF-Animation) on how to mount the Mark III Zoom directly onto any of our 2" Mirror diagonals equipped with a ClickLock-clamp. In case of insufficient backfocus or for permanent attachment onto the telescope (especially suited for public observatories), you can thread the Hyperion Zoom DIRECTLY onto any 2" SC/HD (Celestron-standard) telescope thread (were the Visual-Back fastens usually), or – in case of the Baader 2" ClickLock star diagonal – you can thread the Zoom directly onto the body of the Star Diagonal itself (gaining 47mm in backfocus) – by removing the 2" ClickLock-clamp and adding the Baader ring 2" inner to 2"outer.
