Lunt Solar Systems zoom-eyepiece with variable focal length from 7.2mm to 21.5mm, with 1.25 inch (31.7mm) connection.
FEATURES
The special of this zoom eyepiece is that the optical layout offers highest quality views of the sun, but also on nightsky objects. LUNT minimized the reflections by using superb multicoatings and with care designed internal baffle system and blackened lens edges. The LUNT zoom-eyepiece is not the widest field zoom-eyepiece on the market, LUNT prefered best performance over widest field. The sun and stars are perfect pin point across the entire field of view without any visible distortion. The LUNT zoom-eyepiece is almost parfocal, from one end to the other end of the zooming way you need only 0.5mm to refocuse. The LUNT zoom-eyepiece has a very nice height adjustable eyeguard to protect your eye against day light reflections and to help you to find the perfect eye position.
Please note that these eyepieces are only accessories for existing solar telescopes or filters when observing the sun. Solar observation alone with these eyepieces without additional solar filters is not possible!
