Telescope Eyepieces, Barlows, and Tele-Extenders
Telescope eyepieces determine both magnification and field of view for visual observing. In most cases an eyepiece contains more optical elements than the telescope itself. A carefully chosen eyepiece set will help to maximize the enjoyment of your telescope. Quality eyepieces will maximize telescope performance by allowing it to reach its full potetial. While most eyepieces will perform well in the slower f/10 focal ratio of a Schmidt-Cassegrains, many will not perform well with f/6 faster optics common to Newtonian reflectors and today's apochromatic refractors.
The table below displays popular brand eyepieces from TeleVue, Explore Scientific, Orion and several others. This is a long page, so please be sure to scroll all the way to the bottom.
