Vai al moduloMost telescopes are supplied with one or two simple eyepieces in the set, which do not exploit the performance of the optics. Moderate contrast and sharpness and small field of vision quickly spoil the fun of the sky observation. With Hyperion eyepieces you get everything out of your telescope!
They are suitable for photo! Keep your Astro eyepiece impressions forever by connecting the cameras and camcorders at the Hyperion!
You can distinguish between the series with "Prime lenses" f = 5 mm, 8 mm, 10 mm, 13 mm, 17 mm, 21 mm, 24 mm, the two great eyepieces aspheric 31 mm and 36 mm, as well as the Hyperion zoom eyepiece with infinitely variable focal length of 8 mm to 24 mm.
