More product information
This low profile step-down adapter allows the use of 1.25" eyepieces in 2" focuser drawtubes and 2” star diagonals. It is designed to provide a shorter light path than the standard TeleVue adapter #2715C. This allows eyepieces to swing through the drive base of many catadioptric scopes when using the TeleVue #7782PC 2" SCT diagonal and #7785SC SCT adapter for extra clearance. The 2" barrel of the adapter has an undercut groove that the star diagonal/focuser thumbscrew sits in when tightened down. The extra depth of this groove reduces the chance of the adapter falling out of the focuser should the thumbscrew loosen. To keep your eyepieces looking new, 1.25" eyepieces are held in the adapter by a non-marring soft brass clamp ring rather than an ordinary aluminum thumbscrew that contacts the barrel directly. The thumbscrew that tightens the clamp ring is tethered internally in the adapter so that the thumbscrew can’t be lost in the field.

When using long 1.25" Barlow lenses in a 2" diagonal with this adapter, make sure that the end of the Barlow does not touch the diagonal mirror. If there is such a possibility, use the one-half inch taller #2715C high hat adapter instead to prevent such contact.

Barrel Size:
The industry standard diameter, as of 2011, is 1.25" and is the most common.  Other sizes available are .965" and 2".
1.25"
