This spherical excellently corrected, triplet lens, FCD100 SD APO binocular offers an extremely high contrast. In the basic equipment we have included 1 set 18mm eyepieces. The focal position was chosen so that Tele Vue Delos, Nagler, panoptic, and the Docter 12.5 mm UWA eyepiece can be focused.
Sliding dew shields with front cover plate, a carrying handle with sighting device, a photo tripod adapter with 3/8" thread connection, and 2pc 18mm UFF eyepieces offering 22x magnification are included. For other magnifications, please click here to see our range of UFF (Ultra Flat Field) eyepieces that are specially optimised for low focal ratio optical systems such as these binoculars.
To keep the weight to a minimum, the binoculars housing is made of magnesium. They are now also Nitrogen filled to remove the possibility of fogging in low temperatures.
These 70mm binoculars are bench aligned to 100x magnification before supply to ensure the best performance with a range of eyepieces.
