Note 1: The Celestron Micro Guide eyepiece has an illuminated reticle which includes cross hairs and a variety of micrometer scales for measuring sizes and angles.

Note 2: Eye relief as measured by the author on 1970 vintage 12mm and 32mm Brandons and 16mm and 24mm Questar Brandons.

Note 3: Dimensions, weight, and eye relief as measured by the author. Zeiss no longer manufactures these eyepieces.

Note 4: The visual I3 PIECE is the only product available to the amateur astronomer that provides an intensified 'real time' image of deep sky objects. This is made possible by combining ITT NIGHT VISION generation 3 image intensifier technology with advanced patented optics from Tele Vue.

Note 5: Discontinued, no longer in production.
