Celestron EdgeHD 1400 Reducer Lens.7x Product Info Celestron Edge HD 0.7x Focal Reducer Lens 94240 is a powerful tool for flattening the field seen through your telescope, allowing you to take faster photographs and capture a wider field of view through your eyepiece. These Celestron telescope accessoris use a 5-element lens design to maintain the stellar flat-field performance power of Celestron EdgeHD telscopes, and they increase your telescope's field of view by 43%, allowing you to discover galaxies and star clusters that you would've been able to see only parts of before. Other reducer lenses diminish back focus, making it harder to take good astrophotography photos, but not this telescope accessory; it maintains the same back focus at f/10, allowing you to mount CCD cameras without a loss of resolution. When the Celestron EdgeHD.7x 5 Element Reducer Lens is installed, it will make your telescope's speed one full F-stop above f/10, reducing the necessary exposure time by half, allowing you to take photos twice as fast without any sacrifice of brightness. "Rare earth" lanthanum glass elements minimize chromatic aberration, while the fully multi-coated lenses improve light transmission and color correction. What's more, all lens elements on the Celestron Edge-HD.7x Lanthanum Glass Reduction Lens feature blackened edges to minimize internal reflections and improve contrast. The Celestron EdgeHD 0.7x Fully Multi-Coated Reducer Lens has a full-frame design that mounts directly to the 3.25" threads on the optical tube of an EdgeHD telescope. The telescope accessory has a clear 60mm aperture that is optimized for use with CCD image sensors with a 42mm image circle. The aluminum housing of the Celestron lens is precision CNC machined for precise optical alignment and durability, and threaded metal covers on both ends of the lens assembly protect the integrity of the Celestron Edge HD.7x Focal Reducer Telescope Lens. With this reducer lens installed, you can use all EdgeHD optics at f/10, f/7, and f/2 for incredible versatility. All existing Edge HD T-adapters can be used with the reducer for astrophotography. Get an expanded view of the night sky and take faster photos with the Celestron Edge HD.7x Fully Multi-Coated Focal Reduction Lens.
