This 1.25” Astro-Tech first-surface mirror star diagonal was named a Sky & Telescope Hot Product for 2007! Sky & Tel recognized that the Astro-Tech diagonal would be an outstanding value at even twice its low price. As it is, this Astro-Tech diagonal is unique among 1.25” star diagonals for its exceptional price/performance ratio. This is one premium-quality diagonal that doesn’t happen to be priced like one – and it’s still a hot product for many observers.

This Astro-Tech 1.25” accessory kit includes ten 1.25” Astro-Tech visual accessories specially chosen to get the most out of small to medium size telescopes – from a 66mm refractor to an 8” to 9.25” catadioptric.

Unlike competitive kits that supply only a 50° apparent field Plössl for their medium focal length eyepiece, this Astro-Tech kit gives you a fully multicoated 1.25” four-element Astro-Tech 15mm SuperView eyepiece with an apparent field of view of 68°. It provides an exceptionally wide and dramatic field for observing nebulas, open star clusters, and galaxies. The Astro-Tech 15mm SuperView weighs 3.4 ounces and has a good 11mm of usable eye relief.

The Astro-Tech SuperView has a soft rolldown rubber eyecup to shield your eye from ambient light and improve contrast. It has dust covers for both ends of the eyepiece. Its chrome barrel is threaded for 1.25” filters, and a safety groove is machined into the barrel. This engages the thumbscrew or compression ring of your star diagonal to keep the eyepiece from falling in the dark should the thumbscrew accidentally loosen during use.

Optical tubes based upon the Ritchey Chretien design are known very well for their successfull astrophotography, and the 10" optical tube by Astro-Tech is no different! What is different is the price! This optical tube is boosting quality while saving you approximately $4,000! Astro-Tech has delivered top quality Ritchey Chretien optical tube astrograph for an affordable price! Some of the optical enhancements the observer gets when purchasing this optical tube include quartz mirrors, dielectric mirror coatings, and many more! Sky & Telescope magazine named this one of their "Hot Products" in 2010!

Ritchey Chretien astrograph telescopes are exclusively used in many professional fields, including the HST. Astro-Tech has designed a 6" f/9 Astrograph that is based upon this design to the amateur astronomer at affordable prices. Due to its weight of 12.9 pounds and a supplied Vixen style dovetail, this astrograph is primarily compatible with virtually any equatorial mount, so there is no need to buy an additional mount specific for this scope.

A telescope with high quality optics is key to great observing. However, a high quality telescope priced reasonably is less common. The Astro-Tech 8" Ritchey Chretien is a fabulous optical tube with an excellent reputation for being astrophotography friendly. The telescope features internal optics such as a carbon fiber external body, quartz mirrors, dielectric mirror coatings, and two dovetail mounting rails.

Astro-Tech has built this optical tube by increasing their previous aperture of 66mm to a now 72mm. This allows 9% higher resolution and 19% better light gathering. In addition, a new and updated focuser has been supplied with this telescope.

This green optical tube from Astro-Tech is a piece of equipment every advanced serious astronomer should consider. With high quality refractive optics, fabulous accessories, it is pretty amazing. Some of the key features of this item include the dual speed rotating focuser (10:1 ratio focusing) and high quality ED optics great at preventing chromatic aberration. This scope is so high key, Astronomy magazine designated it previous version a “a great grab-and-go scope, a fine little astrograph, a super-finder scope, and a daytime spotting scope.”. Now, Astro-Tech has added even more to the picture.

This doublet refractor from Astro-Tech comes equipped with a 2" focuser of 80mm travel. The optics in this optical tube a spectacular for inhibiting chromatic aberration, in which lens fail to focus colors equally. This means Astro-Tech has picked the best optical equipment to ensure the observor gets the best possible views and images in their stargazing. The accessories make this telescope even more appealing. For instance, the focuser included is 360 degree rotatable, meaning you can position your CCD camera virtually anywhere you please. The barring on the eyepieces also protect your accessories when mounting them.

This 111mm triplet refractor from Astrotech has an increase of 18% light transmission when compared to a 102mm refractor ota. This telescope is a huge investment, as it can save you a maximum of $800 dollars for a telescope with better optics and light transmission as opposed to other refractors with similar apertures. Featuring Ohara glass, this refractor delivers sharp images that can avoid chromatic aberration.

Astro-Tech has equipped this telescope with a 2.7" Linear Crayford focuser, with a 10:1 focusing ratio. This 360° rotatable focuser allows the observer to place their eyepieces anywhere they please, and the 2" and 1.25" compression rings protect the eyepieces when mounted.

Safe and secure portability is also crucial in extending the life of your telescope and preventing where in tear, so Astro-Tech has included an aluminum-frame carrying case with their 130mm Refractor.
