Radians have a wide field of view of 60°.
They combine superb image sharpness,
a wide field and a long eye relief and
viewing comfort.
The click-stop type retractable rubber eyeguard allows each observer to find
his or her personal viewing distance. You will be able to observe relaxed for long
periods - even eyeglass wearers will see the entire field of view easily.
The eyepieces were designed to offer pinpoint stars to the edge even in short focal ratio telescopes down to f/4.
Eye relief is a constant 20mm, even in the shortest focal lengths. A great difference compared with more simple eyepieces. On axis image sharpness does not suffer from the extra lens elements, the Radians are warmly recommended even to
planet observers.
The eyepieces are of course fully multi-coated and have blackened lens edges. |
