This 1.25” dielectric mirror-type star diagonal was a Sky & Telescope Hot Product for 2007! Considering its performance, it would be an outstanding value at twice the price. At its economical low price, it's still a hot product, and nothing short of sensational . . .
This 2” dielectric mirror-type star diagonal would be an outstanding value at twice the price. At this low price, if there ever was a bargain in astronomy, this is it . . .
Sky & Telescope rated this top-quality and very stable Astro-Tech Voyager altazimuth mount with slow motion controls a “four-star” product. They said it was “a really sweet grab-and-go setup that’s ideal for viewing day or night” . . .
Temporarily out of stock; will charge and ship when available.
This Astro-Tech metal-body straight-through illuminated gunsight-type non-magnifying finder has four different reticle patterns, seven brightness levels, and a two-part mounting base for extra mounting flexibility . . .
This economical Astro-Tech ring system mounts a small refractor on a Celestron or Meade catadioptric scope for use as a finderscope, photoguide, or astrograph . . .
This 2” dielectric mirror-type star diagonal is designed to give you first-class performance with a Schmidt-Cassegrain – at a money-saving and far from first-class price . . .
This flexible plastic rollup dew shield works with the the Astro-Tech AT8RC Ritchey-Chrétien astrograph, most Celestron 8” Schmidt-Cassegrains (except NexStar-type 8" scopes with a full-length mounting bar), and Meade 7” Maksutov-Cassegrains and 8” Schmidt-Cassegrains, except LXD55/75 models . . .
The state-of-the-art 46-layer dielectric coatings on this Astro-Tech 2” star diagonal give its guaranteed 1/10th wave accuracy quartz mirror a full 99% reflectivity for the brightest possible images . . .
The Astro-Tech 2" field flattener improves the image sharpness at the corners of the field with Astro-Tech and TMB apo refractors, but will also work well with any other f/6 to f/8 refractor . . .
These mounting rings fit refractors such as the Astro-Tech AT80 and all William Optics 80mm telescopes (Megrez 80 and ZenithStar 80, for example), plus any other scope with a 90mm OD tube . . .
