Sharpstar 100Q F/5.8 quadruplet apochromatic refractor with FPL-53 optics

The Sharpstar 100Q F/5.8 features a quadruplet oblective lens with 100 mm diameter and 580 mm focal length. It is a pure astrograph with a corrected an illuminated image circle up to 49 mm, perfect for full-frame cameras or even larger. Optical design consists in an air-spaced quadruplet apochromat with japanese Ohara S-FPL53 lens delivering very high color correction. Each optical surface is fully multi-coated with a high light-transmission coating.

It an instrument specifically designed for deep-sky imaging, with a special care for compactness (length of only 490 mm with focuser all racked in) and portability (5,3 Kg with rings and Vixen dovetail included). Focal ratio of F/5.8 is pretty fast, the short focal length and big corrected field of view suggest the use of large DSLR or CCD/CMOS cameras. Given the focal length of 464 mm and big corrected image circle we highly suggest the use of cooled CMOS cameras such as ASI071MC Pro and QHY168C, ASI128MC Pro and QHY128C, etc. for impressive wide-field panoramas.

Even if the instrument has been designed for astrophotography, the Sharpstar 100Q F/5.8 delivers good performances also on visual observations thanks to the very good color correction and optical quality.

The telescope features an oversized 3" rack & pinion focuser with 1:10 micro-focuser. 2" and 1.25" adapter are included. It allows for 360° full rotation thanks to a removable camera rotator. There are also several threads available for direct accessories attachment: M78x1 female, M74x1 male and M68x1 female. Focuser allows for 360° rotation.

Mechanical quality of this Sharpstar 100Q is top-notch: OTA is made with CNC machined light aluminium alloys, light and sturdy. Focuser is of very good quality. Even experienced customers will appreciate quality of this instruments. Nothing is left to chance!
