This Astro-Tech 35mm extension tube is used to make up for the loss of light path when a 2” star diagonal is removed from many refractor focusers and replaced by a camera and camera adapter for imaging. It can also be used with Astro-Tech Ritchey-Chrétien reflectors to bring webcams and DSLRs to the correct focus . . .
This low power wide field 2” Astro-Tech Titan Type II ED eyepiece is great with compact grab-and-go refractors for viewing large-scale deep space objects – open clusters, nebulas, star clouds, and more . . .
This forest green Astro-Tech adapter clamps onto a Losmandy-style "D-plate" dovetail to let you mount a telescope tube ring or accessory on the dovetail . . .
This Astro-Tech 12.75” Vixen-style dovetail rail mounts on top of an Astro-Tech AT6RC 6” Ritchey-Chrétien astrograph to let you mount accessories (such as a photoguide scope) on top of the scope . . .
This 17mm Astro-Tech Series 6 is a good quality medium power eyepiece with a very wide 65° field of view that will add expansive deep space vistas to your observing kit at a price only a fraction that of exotic wide field designs with a similar field of view . . .
This 8mm Astro-Tech Series 6 is a good quality medium to medium-high power eyepiece with a wide 60° field of view that you wouldn’t normally expect to find at such a very reasonable price . . .
After several years of development by Astro-Tech, the 10” Astro-Tech AT10RC Ritchey-Chrétien astrograph is now in production and has been named a Sky & Telescope Hot Product for 2010.

Imitators will copy Astro-Tech’s years of work, but why settle for a copy when you can get the original?
