SkyWatcher Okulārs WA-66 20 mm

Economical eyepieces with a 66-degree field of view, very good multilayer anti-reflective coatings and surprisingly good image correction in telescopes with focal ratios up to F/5. The eyepieces in this series match the image quality of the well-known SWA Plossl 58 eyepieces and surpass popular Erfle eyepieces, offering a large 66-degree field of view that makes it extremely easy for beginners to find objects. This fact, together with the surprisingly low price and comfortable eye relief of about 13 mm, is an excellent offer for those looking for inexpensive eyepieces to replace and extend the eyepieces supplied with telescopes. They are available with focal lengths of 6 mm, 9 mm, 15 mm and 20 mm.
