DiamondScreen Rear Projection Screen with No Frame - 161 diagonal HDTV Format
DR7813: The first rear projection screen designed specifically for video and data projection, this screen is well suited for most A/V applications except those with large vertical viewing cones. This rear screen delivers a brilliant image and unlike most conventional rear screens, the DiamondScreen is cast (molded) and derives its incredible optical performance from its patented Fresnel/lenticular lens system. With its superior center-to-corner brightness ratio this is the world's most sophisticated, most efficient rear projection screen.
Celestron CGE Pro HD 14 Inch EdgeHD Optics Telescope
The CGE Pro 1400 HD combines Celestron's state of the art CGE Pro Computerized Equatorial mount with its new EdgeHD optical system. With more than 60% more light gathering power than the 11'' telescope, this observatory-class instrument is Celestron’s largest optical system in its class. Featuring our premium StarBright XLT coatings, this telescope is especially at home as a solid platform for long exposure photography with optional CCD cameras or photographic equipment; it is a serious scientific research tool. German Equatorial mounts are recognized as being the superior choice for astrophotography because of their rock solid stability, simple balancing and easy accessibility for attaching equipment. With sophisticated software features like the Hibernate function, the CGE Pro can maintain its star alignment night after night without needing to be re-aligned, making it an ideal instrument for a permanent observatory facility Celestron's New Optical Design The Celestron EdgeHD optical system takes all of the compact power popularized by the Schmidt Cassegrain Telescope (SCT) and combines it with an improved high definition optical system for wide field, astrograph quality images. As a visual instrument Celestron EdgeHD optics deliver pinpoint images even with your widest field eyepiece. You can search for all of the Messier Catalog objects, and see hundreds of other equally interesting NGC, IC and Caldwell objects with amazing clarity. For astroimaging, the EdgeHD optics produce aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial ccd detectors, allowing all stars to be in tight focus to the very edge of the chip. Diffraction Limited Some companies boast that their telescopes give diffraction limited stars in the very center of the field of view. EdgeHD optics not only produce diffraction limited stars on axis, but maintain diffraction limited stars across the entire field of view of many of the most popular astrophotography cameras. Even at the very edge of a full frame camera chip, the EdgeHD 14 delivers diffraction limited stars of only 1 arc second! Along with the newly designed optics, the EdgeHD also has re-designed mechanics guaranteed to help you get the maximum performance from your instrument Features Include: Mirror Locks – To hold the mirror in place and reduce image shift during imaging. Tube Vents - Each vent has an integrated 60 micron micro-mesh filter allowing hot air to be released from behind the primary mirror. Fastar Versatility – All EdgeHD optical tubes are equipped with a removable secondary mirror for fast f/2 ccd imaging. Not only does imaging in the FASTAR configuration allow for exposure times that are 25 times faster than at f/10, but
