SharpStar 60ED telescope features:
• 60MM f/5.5 doublet full separation optical design
• Includes one ED lens of Japanese OHARA FPL-53 Super ED lens
• Modular design to meet the different needs of observation and imaging
• New 2" dual-speed rack and pinion focuser, 10:1 fine focus
• 2" and 1.25" universal interfaces
• Angle adjuster for 360 degree rotation
• Universal dovetail bar
• Comes with a star mirror mounting bracket
The SharpStar 60ED refracting telescope is a doublet fully separated design that includes one exotic FPL-53ED lens and multi-layer coating on all surfaces to reduce internal reflections.
The SharpStar 60ED 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.
The SharpStar 60ED provides an impressive focusing system combined with an excellent optical system. The SharpStar 60ED has a high load dual-speed 2-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 accessories.
The SharpStar 60ED is a reasonably priced observational or 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.
In addition, the 60ED can be equipped with a dedicated 2-inch field flattener for astrophotography, which provides excellent image quality and avoids field edge star distortion.
The 60ED has been specifically designed with a soft case to make it easier for buyers to use and shoot when they go out. Product parameters:
