The SharpStar 61EDPH provides a very good observation and imaging system thanks to its fast focal ratio. The unique three-element design incorporates a special ED lens, which helps to control chromatic aberration very well, makes the stars look sharp, and the image more vivid.
The SharpStar 61EDPH provides an impressive focusing system combined with an excellent optical system. The SharpStar 61EDPH has a high load dual-speed 2.5-inch rack and pinion focuser with a 1:10 aspect ratio compared to many refractors on the market that use a toothless focuser (i.e. Crayford). Rack and pinion focusers can bear a higher load due to their construction, so you don't have to worry about wobbling or loosing focus when using heavy-duty observation accessories or a heavy camera. In addition, the 360-degree rotator allows you to easily rotate the camera to achieve the best image framing. The 2-inch eyepiece holder barrel features a brass compression ring, so that you won't scratch your accesories.
The SharpStar 61EDPH is a reasonably priced observational or imaging tool with fast-focus ratio that features exotic super ED glass, high quality heavy duty 2.5-inch rack and pinion focuser; when compared to other similar products on the market, its value is self-evident.
In addition, the 61EDPH can be equipped with our dedicated 2.3-inch field flattener for FULL FRAME astrophotography, which provides excellent image quality and avoids field edge star distortion.
