Meade Series 4000 MA 12mm Wireless Illuminated Reticle Astrometric Eyepiece (1.25”) is a special purpose eyepiece for guiding during long exposure astrophotography as well as taking measurements.

This high precision eyepiece has four different illuminated scales for making astronomical measurements of angles and distances. Fully coated optics delivers contrast images. Rubber eyeguard is helpful for comfortable viewing and blocking distracting stray light.
