Celestron X-Cel LX series eyepieces offer a 60º apparent field of view, perfect for the Moon, the planets, and a plethora of deep-sky objects. The premium six-element optical set is finished with multiple layers of high-transmission coatings for clear, sharp images. The edges of the optics are blackened for increased contrast. All seven X-Cel LX eyepieces sport 16 mm of comfortable eye relief, and are parfocal, which means you can switch out eyepieces within the series during observing sessions and little or no additional focusing will be required. The X-Cel LX eyepiece body is made of black-... [Read More]
Amateur astronomers have to start somewhere. Most begin by buying a modest astronomical telescope and getting to know the night sky. After a while, many want to move on to the next stage, but this can be problematic. The magazines advertise a mass of commercially-made equipment – some of it very expensive – which can represent a major financial outlay. The trick is to choose the right equipment, and then use it to its fullest extent. Observing Skills: The Science and Art of using Astronomical Telescopes provides the required information. First, it explains how to get the best from entry-le... [Read More]
