The SharpStar 20032PNT is the latest product development of a super-fast focal ratio, paraboloid Newtonian reflector telescope from the Chinese manufacturer, Sharpstar. The fast f/3.2 focal ratio of the whole system has been achieved by using a 200mm F/3.8 paraboloid primary mirror, a 90mm plane secondary mirror of short axis and a 3" quartette 0.85x coma correcting optical system. 
Carbon fiber was used to create the tube, which is elegant, durable and lightweight. It also provides best thermal stability when combined with Pyrex glass for the primary mirror.
The SharpStar 20032PNT provides a very good reflectivity (over 96%) thanks to the enhanced  aluminium coating. The secondary cross (spike) is a one-piece molded unit, to ensure firm and secure housing for the secondary mirror. The use of a precision 3" Rack and Pinion focuser offers larger payload and a stronger hold, so that your focuser will not slip when using heavy-duty observation accessories or camera.
The SharpStar 20032PNT is equipped with all CNC-machined aluminum parts and a novelty handle, which takes its mechanical quality and appearance to a new level. The long slot on the handle also allows attachment of other optional accessories, i.e. a guidescope.

The SharpStar 20032PNT features a 0.85x reducing four-element coma corrector that helps to achieve full-frame photography and excellent perimeter dimming control (reduced or no vignetting). 
The focal plane is 55 mm from the M54X0.75 thread at the end of the focuser (from the end of the coma corrector, to be more precise...), and 52mm from the M48x0.75 thread. This "standard" back focal distance provides ample space for any visual or photographic equipment, being it a dSLR or a CCD / CMOS camera.
