Erect Image Diagonal (#94112-A) - This accessory is an Amici prism arrangement that allows you to look into the
telescope at a 45° angle with images that are oriented properly (upright and correct from left-to-right). It is useful for
daytime, terrestrial viewing with refractor and Schmidt-Cassegrain telescopes.
Micro Guide Eyepiece (# 94171) - This multipurpose 1 ¼” 12.5mm illuminated reticle can be used for guiding deep-sky
astrophotos, measuring position angles, angular separations, and more. The laser etched reticle provides razor sharp lines
and the variable brightness illuminator is completely cordless.
Moon Filter (
# 94119-A) - Celestron’s Moon Filter is an economical eyepiece filter for reducing the brightness of the moon
and improving contrast, so greater detail can be observed on the lunar surface. The clear aperture is 21mm and the
ansmission is about 18%. tr
Motor Drive, Dual Axis (# 93522) - This dual axis motor drive, with drive corrector capabilities, is designed for Celestron's
Omni CG-4 mounts. It precisely controls the telescope's tracking speed during long, timed exposures of celestial objects,
