SIGHTRON Comet Scan 12x63 Binoculars for Astronomical Observation, Comets, and Natural Observation (B377)

* Employs a large-aperture objective lens with excellent light-gathering power. Ideal for observing faintly emitting objects such as comets, nebulae, and star clusters.

* Suitable for use beyond astronomical observation, including wildlife observation in dim light environments such as dawn and dusk, and for security and other professional applications.

* Uses BaK4 glass for the prisms. Combined with full multi-coating on all lens surfaces, it achieves high light transmission and color reproduction.
