Everything you need, all in one kit! Orion 20mm Illuminated Centering Telescope Eyepiece. For testing the accuracy of your tracking system, or centering stars for GoTo system alignment, the wide field of the Orion 20mm Illuminated Centering Eyepiece makes it easy.
Just use the illuminated crosshair to acquire and center any star. At the budget end of the market, three-element meaning they have three lenses inside eyepieces labeled Kellner or "MA" modified achromat can turn in a good performance with scopes of long focal ratio, such as Schmidt-Cassegrains and traditional refractors.
They do not work well with telescopes of short focal ratio. The latter is a good all-rounder, particularly when antireflection multicoated. It is worth pointing out that observers who wear glasses to correct for simple long- or short-sightedness no astigmatism don't need to use them at the telescope; a twist of the focuser will remedy that. High-power lunar and planetary viewing entails the use of short-focal-length eyepieces, which can be a problem owing to the small eye relief of conventional designs.
This has spawned the development of six- to eight-element designs that combine comfortable eye relief and wide apparent fields across the focal-length range. They may feature exotic rare-earth glass elements to reduce optical aberrations still further. Many regard these Lanthanum and Ultrawide designs as the pinnacle of eyepiece evolution and rightly so , but for many people the price will be a barrier — and their physical size and weight may be an issue for delicately balanced small scopes.
While the Barlow is not strictly an eyepiece, our discussion would not be complete without mentioning this enormously valuable accessory. A Barlow is inserted into the telescope's focuser before the eyepiece and instantly doubles or triples, in some instances the magnification. At the expense of a small loss of light, this very useful device can double your eyepiece investment by making each perform at two powers. If you are contemplating purchasing a Barlow with a set of eyepieces, give some thought to staggering the focal lengths so that they are not simple multiples of one another: a 10 mm eyepiece is largely redundant if you use a 20 mm and a Barlow.
Look for "achromatic" and "multi-coated" specifications when shopping around. Ashford January 25, By: Gary Seronik January 8, By: Jerry Oltion November 26, By: Alan Dyer November 6,
