About

A three-part camera adapter for 1.25" focuser refractors and reflectors. The one-piece prime-focus section works alone for prime-focus imaging; adding the two nested projection tubes gives eyepiece projection at a distance adjustable from 90 mm to 125 mm, varying image size by 44% without changing eyepiece.
