Deluxe 2" Extension Tube
Provides an additional 2 3/8" of back focus. All aluminum anodized parts with rubber grip, brass compression ring, filter thread on insert tube and beveled insert which improves the snugness of the fit as the lock screw is tightened. Works well with our FA2 1 1/4" adapter. #ET3

Long 2" Extension Tube
Same as ET3 above but provides a full 4.75" of extension. For use only with our binoviewing telescopes in place of a threaded extension for more convenience.
We recommend this unit be used with the Feather Touch focuser as it has a greater lifting capacity that standard Crayford focusers.

1.25” ‘High Hat’ Adapter

1.25" Compression Ring Adapter
adapter for 2" diagonals. Uses a compression ring to safely hold eyepieces and has the insert safety groove on the outside. Knurled top and threaded for filters. If using this adapter, a 1.25" diagonal and our Crayfod focuser, some 1.25" eyepieces may not come to focus. In this case, use the FA above. #FA2
