Apertura Self-Centering 35 mm Extension Tube - 2"

By increasing imaging set-ups by 35 mm or 1.38", this CNC-machined Self-Centering Extension Tube helps users achieve focus. Additionally, extension tubes can also enable an eyepiece to be focused for visual observing when used with a telescope designed for imaging. Measures 2" in diameter with a total length of 50 mm. Threaded to accept 2" filters.

Securely held via a helical compression mechanism, this Apertura Self-Centering Extension Tube will both accurately center your 2" accessory and keep it in place. With this type of holding mechanism, your inserted barrel will not be moved laterally, making it preferable over the simple thumbscrew locking system. Using this extension tube requires only a simple rotation of the knurled top ring to lock in your accessory, and a twist in the opposite direction for removal. In addition to accurately centering your 2" accessory, this adapter is also easy to use, even in the dark.
