Telescope drawtube extensions help your telescope reach focus when not using a diagonal — as is the case in many imaging applications. They are also useful (with or without diagonal) when you need more out-travel for focusing on nearby terrestrial subjects.

Our extention tubes slip into any telescope's 2" drawtube and include brass clamp rings to prevent marring of accessory barrels.
