Refraction series

Modern astronomical telescope can be divided into refractor, reflector and catadioptrics, and the refractor is of non-sheltered aperture and high-contrast. In order to eliminate chromatic aberration, ultra-low dispersion glass is commonly used.

20032PNT

SHARPSTAR's newly developed ultra-short focal ratio paraboloid Newtonian reflector 20032PNT was launched, which filled a domestic gap in this field. The focal ratio of the whole system reached F3.2 by using a 200mmF3.8 paraboloid, a 90mm plane secondary mirror of short axis, and a 3-inch quartette 0.85 times error correction mirror, has been leading in the domestic market of similar products. Carbon fiber main tube is light, durable and so elegant appearance, which uses Pyrex materials is more stable than conventional reflective materials.

76EDPH

SHARPSTAR's bran-new 76EDPH is the second model in the EDPH series, and the overall appearance is streamlined and cool design. The lens adopts the triplet air-spaced structure, one of which uses ultra-low dispersion ED glass, which ensures that the chromatic distortion can be eliminated regardless of the visual or astro-photograph, and the image formation is more distinct and vivid.The aperture is 76MM, which adopt the focal ratio of F5.5, and the focal length is 418MM. When the dew-shield is retracted, the total length of the lens tube is only 332.9MM. It is short and portable, and it is easy to put it into a travel bag or take it on the plane. It is a good partner for the outdoor expedition. A high-performance optical design and machining processing ensure the great quality of 76EDPH, particularly the 2.5 inch F4.5 full-frame reducer designed for all photography, which makes this telescope model become with short focal ratio high-quality astrophotograph.

15028 HNT

The SharpStar 15028HNT is our latest product and development of super-fast focal ratio, hyperboloid and Newton reflecting telescope, which makes up the domestic gap in this field. Hyperboloid is much more complicated than traditional paraboloid, no matter in development, manufacture or detecting requirements. When compared to other similar products on the market, The SharpStar 15028HNT is in the leading position. Carbon fiber was used to create the lens barrel material, which is beautiful, durable and lightweight. It also provides best thermal stability by using Pyres glass.

61EDPH and F4.5 reducer

61EDPH and F4.5 reducer Technology is developing so fast, there is a big boost in people’s demand for goods. In recent years, some new changes have taken place in the field of astronomy products. With the popularization of digital cameras and people’s increasing love of astronomy photography, an all-round equipment that features photography and suitable for observation is needed to meet customers’ demand. SharpStar 61EPH occurs under this background. This telescope features a two-element fully separated lens design with a focal length of 335mm and a focal ratio of f/5.5. The use of one extra-low dispersion glass elements makes the overall tube shorter and more portable. The dedicated unitary tube rings with hollow design and streamlined handles is fashionable and beautiful and you can add some accessories to connect. The 61EDPH package also contains a 10cm dovetail plate, it have a screw-hole in the center that allows the camera to be mounted to a tripod for photography. The back-end is equipped with a middle 2.5" rack and pinion precision focuser to be used with a large dedicated reducer. The following discussion will focus on the dedicated full-frame reducer of 61EDPH, because it meets the need of full-frame photography. The reducer is equipped with a 2.3" tube, one end of which adopts a M63×1 thread and connects to the pinion focuser of the primary mirror. The other end adopts a M48×0.75 thread, the focal plane is 55mm from the end interface. If you need to expand, it can measure up to 99mm by removing the end interface and adapting your own accessories, which fully meets the requirements of a wide range of photographic accessories. The reducer features a three-element fully detached structure, which helps to support full-frame photography and achieve excellent perimeter dimmer control. The reducer is specifically designed for deep-space widefield astro photography with a focal length of 275mm and a focal ratio of f/4.5. In addition, the 360-degree rotator allows you to easily rotate the camera to achieve the best image framing.
