Description
The TS-Optics 102/1122 F/11 ED 2.5" RAP is an exceptional optical tube that offers a perfect blend of features for both observation and astrophotography enthusiasts.
At the heart of this telescope is a two-element optical system that ensures unparalleled image quality with precise correction of chromatic aberration. The low-dispersion lens, crafted from FPL-51 glass, represents one of the finest optical materials available today. Not only does it possess a high Abbe number (81.54), indicating superior optical performance, but it also boasts excellent chemical stability, ensuring durability against external elements.
Equipped with a sturdy 2.5-inch diameter rack & pinion focuser, this telescope guarantees linear operation, even when accommodating large SLR cameras. The focuser also features dual-speed knobs, enabling effortless and precise focusing.
In addition to its remarkable optics, the TS-Optics 102/1122 F/11 ED 2.5" RAP stands out for its robust yet lightweight construction. With an optical tube weighing only 4.6 kg, this telescope can be easily mounted on an EQ5 class mount.
