The Short 2" SCT Adapter with 2" Female Output is made to allow catadioptric telescopes with standard 2" SCT threading to accept standard, unthreaded 2" push-fit diagonals, eyepieces, and accessories. It is often referred to as a 'visual back', and often comes standard with telescopes. This is Lumicon's shorter version, adding 0.45" of back focus versus the standard LA1065 model (some rare catadioptric scopes can have problems reaching infinity focus).
On the 'front' (where light would enter) there is a female 2" SCT threading, and upon the rear (where light would exit) there is a barrel with a 2" inner diameter and a pair of set screws to affix your 2" accessory.
When using a visual back alternatively with and without a diagonal, it may be necessary to add a JMI Extension Tube.
Adapts catadioptric scopes with 2" SCT male threadings to accept 2" accessories
Low profile design to ease reaching infinity focus with scopes having limited in-travel
