About this product

Model:  sharpstar_2032pnt
Part Number:  2032PNT

Optical Bench Test

All SharpStar telescopes are tested in the UK on an optical bench. 

This ensures you can be confident your telescope will, from the outset, have well figured optics, negligible false colour and spherical aberration, and no astigmatism (the bane of any optical system!). Star shapes will be round, not triangular, oval or egg-shaped!

SharpStar 20032PNT Paraboloid Newtonian Astrograph

The SharpStar 20032PNT Paraboloid Newtonian Astrograph is a compact 200mm f/3.2 reflector using an innovative optical design and multiple precision elements to provide a 44mm image circle that fills 36mmx44mm full-frame sensors with an ultra wide 6 degree field of view. This is the ideal instrument for astrophotographers looking to capture wide field deep sky targets with a super fast optical system.

The fast f/3.2 focal ratio arises from the integration of an F3.8 200mm hyperbolic primary mirror with enhanced aluminium coatings with 96% reflectivity. This type of mirror  delivers reduced aberration and field curvature at the edge of the wide field of view. The large 90mm secondary mirror of short axis and a 3-inch four-element 0.85x error-correction mirror passes light through a three-element corrector lens to deliver a crisp, sharp, and bright image over the entire 44mm image circle with minimal chromatic aberration and outstanding field flatness and a focal ratio of F3.2.

The primary and secondary mirrors are all made with an aluminium reflective coating together with a protective coating for durability, reflectivity is better than 96%. The mirror cell also includes a fan for fast cooling and acclimatisation (power source sold separately).

A 3-inch geared focuser ensures smooth operation without slipping, even with relatively heavy loads. The end of the focuser includes M54×0.75 threads. The back focus is 55mm from the M48x0.75 threaded adapter so Nikon/Canon DSLRs will readily come to focus when used with a wide 48mm camera-specific T ring (not included).

The SharpStar 20032PNT is engineered and constructed to be durable for field use, yet portable and lightweight enough to make it easy to mount and handle. 

The20032PNT ships with a Losmandy style dovetail plate, an innovative and attractive carry handle on top, and a hard-sided carrying case.

The total weight of the SharpStar 20032PNT with all accessories is just 9.46kg (20.8 lbs), making it an ideal match for many medium-capacity portable equatorial mounts.
