This Astro-Tech 2" x 50mm extension tube is used to make up for the loss of light path when a 2" star diagonal is removed from many refractor focusers and replaced by a camera and camera adapter for imaging. It can also be used with Astro-Tech Ritchey-Chr├ętien reflectors to bring webcams and DSLRs to the correct focus . . .
