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

Doing Photography with DSLRPros: Cons: Comments:
Use this with Eyepices 2" parfocal rings so i can have DSLR camera and eyepices all parfocal, makes photography easier and no need to get a longer focuser tube on visual that would intrude into light path.Well made tele vue quality as expected.

Excellent Extension TubePros: Cons: Comments:
I like the design using an inner ring to prevent scuffing items that are clamped in this tube. The machining and finish is very good. I’m a mechanical engineer and I have designed and machined tubes like this before.
