The SharpStar 50ED refracting telescope is a doublet fully separated design. 
The SharpStar 50ED provides a very good observation and shooting system thanks to its fast focal ratio. The unique doublet design incorporates a special ED lens, which helps to control chromatic aberration very well, makes the stars look sharp, and the image more vivid.
Aluminium alloys was used to create the lens barrel material, which looks beautiful and offers a unique style. It also reduces the weight of the lens barrel. The net weight of the whole OTA is only 1120g, which is very easy to carry.
The SharpStar 50ED also comes with an impressive focusing system while providing an excellent optical system. The SharpStar 50ED comes with a precision 2" rack and pinion dual speed focuser. Compared with many refractors on the market, the use of a rack and pinion focuser offers larger payload and a stronger hold, so that your focuser will not slip and you don’t need to be worried about being out of focus or badly framed image when using heavy-duty observation accessories or camera. The 360-degree rotator allows you to easily rotate the shooting angle and correct the framing to your own satisfaction. The focuser's SCT thread and 1.25" international standard interface with brass compression ring does not let your accessories to scratch.
The SharpStar 50ED is a reasonably priced observational and imaging tool with fast-focus ratio that features exotic FPL-53 super ED glass, high quality heavy duty 2-inch rack and pinion focuser; when compared to other similar products on the market, its value is self-evident.
