Sharpstar 100Q II APO ED 100/580 f/5,8 quadruplet

The Sharpstar 100Q II APO ED 100/580 f/5.8 is the latest iteration of the highly esteemed Sharpstar 100Q model. This remarkable telescope falls within a rare category of refractors that seamlessly combine the capabilities of a professional astrograph with a high light transmission and visual observation capabilities.

One of the standout features of this telescope is its ability to deliver exceptional image quality with impeccable correction of chromatic aberration and field curvature. This is made possible by the advanced optics employed in its apochromatic quadruplet system, featuring a single lens crafted from low-dispersion glass (ED). Furthermore, all optical surfaces are coated with a full multilayer coating (FMC), effectively eliminating internal light reflections and significantly enhancing image contrast.

The optical tube is equipped with a robust 3.2" focuser, which works in tandem with a rack & pinion mechanism boasting a 1:10 gear ratio and a dual-speed knob. This configuration ensures precise focusing adjustments for achieving the perfect focal point. Moreover, the focuser is designed to handle heavy loads, making it compatible with full-frame cameras and digital SLR cameras. The inclusion of a rotator enables convenient 360° rotation, allowing users to select the desired perspective for capturing frames.
