This multi-function guiding eyepiece features a laser-etched reticle with a built-in battery illuminator. The eyepiece is a multicoated 12.5mm Abbe (4-element) Orthoscopic.
Usage possibilities include: direct guiding on stars outside the center of the field of view; greatly improved off-axis guiding to capture much fainter, sharply focused guide stars without reducing limiting magnitude; and measuring position angles and separation of double stars.
The Micro Guide Eyepiece is totally free of internal reflections and offers sufficient eye relief for the reticle to be viewed easily, even with eyeglasses. Its finely etched micrometer scale has gradations 50 microns apart and 15 microns wide. Included are: the eyepiece, built-in cordless illuminator with adjustable brightness control, batteries and instructions. The apparent field of view is 42°.
