Sharpstar 100Q II APO ED 100/580 f / 5.8 is the latest version of the highly regarded Sharpstar 100Q model belonging to an extremely narrow range of refractors, which include instruments that successfully combine the features of a professional astrograph with high light intensity and a telescope for visual observations.
Obtaining excellent image quality with perfectly corrected chromatic aberration and field curvature is guaranteed by the optics in the apochromatic quadruplet system with a single lens made of low-dispersion glass (ED). In addition, all optical surfaces are covered with a full multilayer coating (FMC), which by eliminating internal light reflections significantly improves the contrast of the image obtained.
The optical tube is equipped with a reinforced cut with a diameter of 3.2 ", cooperating with a rack & pinion mechanism with a ratio of 1:10 and a dual speed knob, which facilitates the perfect setting of the point of focus. the extractor has been developed in a way that allows the transfer of high loads (full-frame cameras, digital SLR cameras), and the additional rotator, 360 ° rotation allows you to conveniently select the perspective of the photographed frame.
