This Astrograph from SharpStar is a new design which fills a previously existing gap in the astronomical telescope market place.\u003c\/p\u003e\n\u003cp\u003eCompared with conventional parabolic mirrors, the process of producing, manufacturing, and testing Aspheric mirrors is much more intricate, and opticians know that these mirrors require more sophisticated testing to obtain the desired Aspheric surface figure. The Aspheric Super Cassegrain Astrograph Reflector is second to none, considering its focal ratio, aperture, and well corrected imagery. This f\/5 Aspheric Super Cassegrain Astrograph from SharpStar uses an Aspherical primary mirror and a Spherical secondary mirror in its reflective design, with the addition of a 3\", 3-element refractive corrector, which is built into the optical path of the assembly inside the tube.\u003c\/p\u003e\n\u003cp\u003eThe telescope tube is wrapped with durable carbon fiber material, artistically enhancing its appearance while sharply decreasing its weight.

Both primary and secondary mirrors have an enhanced aluminum coating, thus keeping a reflectivity at more than 95%. The one-piece X-shaped strut of the secondary mirror keeps a solid and unbreakable structure. The included 3.3\" Rack-and-Pinion focuser has a stronger load capacity and longer 50mm travel length.   It can be smoothly adjusted for best focus, with its dual, 1:10 fine focus adjustment.\u003c\/p\u003e\n\u003cp\u003eThe delicately pierced handle bar is made from CNC-manufactured solid aluminum, which can be used as a base for the attachment of other accessories.
