The optics appear clean and without markings. There are minimal cosmetic imperfections on the metal housing. Includes a filter drawer for 2\" threaded filters. Also includes stock dust caps for both sides of the lens assembly and high quality padded fabric storage case. Adjustment screws are all present along with Teflon bushings. Camera side threads are M42 on filter drawer and M48 on Hyperstar.\u003c\/p\u003e\n\u003ch2\u003eOverview\u003c\/h2\u003e\n\u003cp\u003e\u003cspan\u003eThe evolution of intelligent design has continued with version 4 of the HyperStar 8. Version 4 is faster at f\/1.9, has a larger imaging circle of 28mm, and produces significantly improved 30% smaller spot sizes. The design of the housing has also been modified to improve the ease and accuracy of collimation.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003e\u003cb\u003eFeatures\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe HyperStar 8 lens converts a standard Celestron 8\" SCT from f\/10 to f\/1.9, making the system 25 times faster. That means 25-times shorter exposures! Now you can capture deep-sky images without guiding and without an equatorial wedge (in alt-az configuration). The HyperStar lens shortens the focal length of the telescope, giving a much wider field of view, and giving a greater tolerance of tracking errors, allowing for unguided, alt-az imaging.\u003c\/p\u003e\n\u003cp\u003eThe HyperStar 8 is compatible with a variety of cameras, including CCD, CMOS and DSLRs. The HyperStar 8 covers up to a 28mm sensor size. Separate adapters are required for different cameras. One adapter is included with the HyperStar lens.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eOptical performance is excellent, with a coma-free, flat field of view up to 4.1 degrees wide.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cimg style=\"float: none;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0869\/6486\/files\/HyperStar-Comparison-c8_large.jpg?v=1544562923\" alt=\"\"\u003e\u003c\/p\u003e\n\u003ch3\u003e\n\u003cb\u003eFAQs\u003c\/b\u003e\u003cspan\u003e \u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cb\u003eDo I need the Filter Slider to use Filters with the HyperStar?\u003c\/b\u003e\u003cspan\u003e\u003c\/span\u003e\n\u003c\/h3\u003e\n\u003cp\u003eNo, the standard camera adapter that comes with the HyperStar allows the use of one 2” mounted filter.

Although, the fast F\/Ratio does make the camera’s backfocus much more critical.
