SKY ROVER 100mm 45° APO GIANT BINOCULARS
The Sky Rover 100mm 45° APO Giant Binoculars are high quality and excellent value for money, featuring air-spaced apochromatic doublet lenses with Super ED extra-low dispersion elements for exceptionally high contrast views of astronomical and terrestrial objects.
The integrated dew shields protect the lenses during long observations and can be used as a light shade during daytime viewing. The binoculars include a tripod mounting connection and a heavy duty carrying handle. The nitrogen-filled housing is weatherproof and made of magnesium alloy for maximum rigidity and lightness.

Sky Rover binoculars are designed to provide comfortable focus position with a range of eyepieces. The interpupillary distance can be adjusted and each eyepiece can be individually focused thanks to the dual helical independent focusing system.
Two Sky Rover UF 18mm eyepieces are included as standard. These give a magnification of 30.5x and a field of view of 1.96°. The 18mm eyepieces can be replaced by any of the Sky Rover UF series 1.25" eyepieces as shown in the table below.
| Eyepiece | Magnification | Field of View |
| Sky Rover UF 4mm | 137.5 x | 0.44° |
| Sky Rover UF 10mm | 55 x | 1.09° |
| Sky Rover UF 15mm | 36.7 x | 1.64° |
| Sky Rover UF 18mm | 30.5 x | 1.96° |
| Sky Rover UF 24mm | 22.9 x | 2.62° |
Note: It is highly recommended to mount these on a tripod such as the incredibly sturdy Geoptik Binoplus Pantograph mount or Sky Rover U-Mount. For extra stability, we suggest attaching one of the below Vixen-style dovetail bars to the binocular's mounting plate.
