The RVO 12.5mm illuminated reticle is an superb eyepiece for aiding drift alignment and other forms of OTA alignment.

High quality 1.25" wide angle eyepieces. A superb upgrade from the standard eyepieces that come with most telescopes. Unlike the plossl eyepieces that are generally 52° field, these WA eyepieces give an impressive 68° field

This handy adaptor allows you to use a Canon EOS lens with either a T2 camera or a 1.25" push fit camera.

RVO 2" coaxial extension tubes simply push into a 2" opening then the brass ring expands to secure into any 2" holder, then has either an M42 or an M48 fitting on top.

First published in 1999, this much expanded and updated edition of the best-selling handbook Astrophotography for the Amateur provides a complete guide to taking pictures of stars, galaxies, the Moon, the Sun, comets, meteors and eclipses, using equipment and materials readily available to the hobbyist.

One of the characteristics of the Newtonian telescope design is the location of the eyepiece near the open end of the optical tube. Frequently, stray light travels over the opposite side of the optical tube and prevents optimal viewing. Astrozap's Light Shields block stray light from interfering with dark adaption and concentration, thereby enabling a more enjoyable observing experience. Astrozap Light Shields are proudly made in the USA of ABS plastic for maximum durability, ease of care and appearance.
