All of the lenses in the air-spaced triplet optics of the AT130 are fabricated from Ohara glass (Ohara is Japan’s premier manufacturer of specialized optical glass), including the first-quality FPL-53 center element.
The result of using the best possible glass is the finest possible control of spurious color. The AT130 images are free of all vestiges of the annoying faint color halos around bright objects visible in lesser scopes – despite the Astro-Tech’s fast focal ratio, and even at very high magnifications.
Those exceptional optics come in a finely-machined body with a newly-designed dual speed 2.7" linear Crayford focuser with a microfine 10:1 fine-focusing ratio. The focuser can rotate a full 360° to put your camera or eyepiece in the most comfortable observing position. The supplied 2" and 1.25" eyepiece holders use non-marring brass compression rings that won’t scratch your eyepiece barrels. The Astro-Tech AT130 has a retractable lens shade and comes in a locking aluminum-frame carrying case.

Also would like to know how much difference can I expect when going from the AT111 to the AT130 aside from the weight difference. How about optics? Will I get any noticeable improvement? Will the F/6 AT130 be better than the f/7 AT111 for imaging deep sky objects?
