Starlight Instruments "Shorty" Adapter for 0.8" Travel Focuser on 10" Meade SCT

This adapter threads onto the rear cell of 10" and larger aperture Meade catadioptric telescopes to allow a Feather Touch focuser with 0.8" of drawtube travel to swing through the telescope fork arms. 

This 1.25" tall non-vignetting adapter is designed to allow a 0.8" travel Feather Touch focuser with optional internal brake system to swing through the fork arms of a 10" Meade Schmidt-Cassegrain telescope. It can be used with any 12", 14", and 16" Meade scope as well, but is particularly recommended with the 10" scopes, due to the limited pass-through clearance available for accessories with this size scope. Its special wide-mouth design eliminates vignetting during wide field visual observing with long focal length wide field 2" eyepieces and during astrophotography.

It has 3.25" diameter internal threads on one end that attach to the large rear cell thread of the above telescope. The 3.25" to 2" step-down adapter ring normally attached to the rear cell of the scope must be unthreaded and removed to use this adapter. The opposite end of the adapter has a 2.75" diameter opening that accepts the body of a 0.8" travel Feather Touch focuser. Feather Touch focusers with longer drawtube travel can be used, but will quickly bottom out on the adapter and prevent the focuser from swinging through the fork arms. Three recessed setscrews in the adapter fit into a groove in the Feather Touch focuser body to lock the focuser in place. Precision machined of aluminum and black anodized.
