Eyepieces for planetary viewing The X-Cel LX series includes focal lengths from 2.3 to 25 mm and two Barlow lenses. Larger view The Celestron X-Cel LX eyepieces are high quality eyepieces that have been designed with a view to planetary observation and for convenient and comfortable viewing. Two Barlow lens (which of course can be combined with all other 1.25 "eyepieces) complete the series. The brass clamping ring ensures a secure grip and prevents scratches on the eyepiece. The Celestron X-Cel LX 2x Barlow doubles the focal length of your telescope without changing the other properties of the eyepiece (Apparent field of view, eye relief, eye relief). So you can achieve two magnifications with an eyepiece. This is especially useful if you want to avoid the uncomfortable viewing behaviour of many short focal length eyepieces. Please note that the specified extension factor only applies when the eyepiece is inserted directly into the Barlow lens. For example, if an additional diagonal mirror is used between eyepiece and Barlow lens, the magnification is increased by a multiple. Barlow lenses are particularly short design, so you can safely use with a diagonal prism also, without having to fear that Barlow could rest on the valuable prism. She does not protrude further into the eyepiece into it as a normal 1.25 "eyepiece. The brass clamping ring holds your eyepieces securely without scratching it. The Barlow lens is fully multi-coated (fully multi-coated) for clear, sharp images. The housing has an easy grip rubber coating that provides a firm grip at all times - even with dew in autumn. Versatile: The Barlow doubles the focal length of the eyepiece, which are inserted into it, and can be used with virtually any telescope. Larger view Barlow lenses are not only helpful for visual magnification of the telescope to achieve the necessary for planetary viewing with high magnification long focal length eyepieces. Also photographers know quality Barlow lenses to appreciate: It is to max out modern video cameras, as they are used for planetary imaging because of their pixel size if the telescope has a focal ratio of f/20 f/30, i.e. if the focal length is 20 to 30 times longer than the diameter of the opening. Therefore, the X-Cel LX Series Barlow lenses offer dual or triple focal length. With the X-Cel LX Barlow 2x long focal length telescopes achieve an interesting focal ratio for planetary imaging - here with the Celestron NexImage 5 Telescopes with lenses with longer focal lengths like Schmidt-Cassegrains, Maksutows or classic lens telescopes in accordance with Fraunhofer, the 2x Barlow is usually the right choice for short focal length telescopes, as well as for many Newtons or for large field observation designed lens telescopes, the 3x Barlow is suitable.X-Cel LX 2x Barlow Overview Magnification: 2xRemuneration: Fully Multi-CoatedPlug-in connection and filter thread: 1.25 inches Weight: 140 g Accessories: Dust protection cover Length: 75mm Length without 1.25 "- push-on sleeve 46mm
