Sky Rover Optics 150 APO BINO STRAIGHT Binoculars (Sky Rover Optics, SKU: 86800) are large-aperture straight-through binoculars designed for astronomical observing as well as detailed observation of nature and distant terrestrial objects. Each optical path uses a 150 mm objective with an 840 mm focal length, constructed as an air-spaced apochromatic doublet containing a Super ED glass element. The interchangeable-eyepiece design allows the magnification and field of view to be matched to the observed target, while the straight-through optical path makes it easier to aim the binoculars intuitively.
