Large barrel 2" eyepieces permit wide fields of viewing impossible to achieve with eyepieces of smaller barrel diameters. The focusers of all Meade DS-Series telescopes, except for DS-60 models, include 2" eyepiece-holders to accept the oversize #937 Diagonal Mirror-which in turn accepts eyepieces of 2" barrel diameters. An adapter is included to allow for the use of standard 1.25"-barrel eyepieces in the 2" Diagonal Mirror as well. The #937 is only required for DS Series refractors, and is not required upon reflecting DS Series telescopes.
