Celestron 1.25-inch Observers Accessory Kit, Black

The Celestron Observer’s Accessory Kit is a great way to expand the functionality and enjoyment of your telescope. Inside the plastic, foam-lined carry case you’ll find these accessories: 17mm Plossl Eyepiece - 1. 25-inch, 6mm Plossl Eyepiece - 1. 25-inch, 2x Barlow Lens/T-Adapter - 1. 25-inch, 80A Blue Filter - 1. 25-inch, 25 Red Filter - 1. 25-inch, Moon Filter - 1. 25-inch, Microfiber Cleaning Cloth. Eyepieces - The 17mm and 6mm Plossl eyepieces can be used in any telescope with a 1. 25-inch focuser. Each eyepiece features a four-element design with a 52 degree apparent field-of-view. The lenses are fully multi-coated to improve light transmission and protect the optics. The 17mm Plossl eyepiece offers a nice medium magnification view in most telescopes and the 6mm Plossl provides high magnifications, great for the Moon and planets, especially when seeing conditions are good. 2x Barlow Lens/T-Adapter - The included versatile 2x Barlow will double the magnification of any 1. 25-inch eyepiece. The 17mm Plossl included in this kit will double in power, effectively becoming a 8. 5mm eyepiece and the 6mm will provide the magnification of a 3mm. Any other 1. 25-inch eyepieces you already have will also work in this desirable accessory, giving you even more magnification choices. Remember, high magnifications do not always produce clear, sharp results, especially on evenings of poor or moderate seeing conditions. Filters - Colored filters bring out certain details on a planet’s surface or its cloud structure. Both planetary filters, as well as the Moon filter, can be used on any 1. 25-inch eyepiece with the proper filter threads. Just screw one onto your eyepiece of choice and slide it into the focuser. The Moon filter is one of the first accessories most new amateur astronomers buy and for good reason. It helps block out a portion of the light the Moon sends into your eyepiece so you can see details better.
