Tele Vue Accessory Tube Set for 2.4" - (1 & 2mm)

This Accessory Tube Set for 2.4" is comprised of two imaging-system extension tubes. One tube is 1mm in length, while the other tube is twice as long at 2mm.

These tubes allow the user to establish the correct distance between a field lens and an imaging device. These black anodized aluminum rings feature reflection-reducing threads that enhance image contrast by reducing the possibility of internal reflections.
