Apertura Self-Centering 50 mm Extension Tube - 2"

For customers in need of help obtaining focus with their current imaging configuration, this CNC-machined self-centering Extension Tube supplies an additional 50 mm (1.96"). Extension tubes are also a great way to get a telescope dedicated for imaging to focus an eyepiece for visual applications. Measures 2" in diameter and 85 mm in total length. Barrel threads accept 2" filters.

This Apertura Self-Centering Extension Tube uses a helical compression mechanism to securely hold in place, as well as accurately center, your 2" accessory. Compared to a simple thumbscrew locking method, this type of holding mechanism is favored because it won’t push the inserted barrel sideways, thus keeping your accessory centered. To use the self-centering extension tube, simply rotate the knurled top ring to lock your accessory in place, and twist in the opposite direction to release it. You will not only have a centered accessory, you will find that operating this type of adapter is much easier, especially in the dark.
