Lunt Solar 7.2mm-21.5mm Zoom Solar Eyepiece - LS7-21ZE (OPEN BOX)

The Lunt Solar Eyepiece series are coated with the same 0.1% anti-reflective coatings as on their h-alpha etalons. The anti-reflective coatings reduce ghosting and glow and aid in providing darker background. They also excel at lunar and planetary viewing - as well as terrestrial objects. With 7.2mm-21.5mm Zoom power, it'''s like having a whole set of eyepieces rolled into one!

Lunt Solar Eyepieces have other great features as well, such as a safety groove cut in the barrel to help stop eyepieces from accidentally falling out of the focuser, rubber eyecups to help prevent stray light, gnurled grip rings and an attractive flat black design.

What''s more, Lunt Solar Eyepieces provide comfortable eye relief at all focal lengths in a multiple-element design. They also feature a very generous field of view. It''s an all around performer!

Safety Note: These are eyepieces only and must be combined with a safe solar filter for viewing the Sun!
