The Meade #930 2.00" mirror diagonal attaches to the rear cell of all Meade LX-series telescopes and permits the use of wide field 2.00" eyepieces. Each diagonal includes a Meade optical-flat mirror of Pyrex glass, UHTC-coated for maximum reflectivity. 90° Star diagonals, the term often associated with mirror-based systems such as this, render images which are upright but laterally reversed. They are brighter than systems yielding perfectly upright and laterally correct images, which is important when you're trying to squeeze the last bit of magnification out of your telescope.
The #930 will work with the #1209 Zero Image Shift Microfocuser.
