These high-power binoculars are perfect for astronomical observation. The large objectives collect plenty of light, and the Image Stabiliser ensures that hand-held viewing is jitter-free, which is especially important at such a high magnification. These binoculars are also weather sealed and have anti-fog coatings, so they can be used in any weather. Image quality is ensured by advanced Canon optics, including a multi-coated Ultra-Low Dispersion element in each objective section. These binoculars feature a comfortable, ergonomic design, so they are comfortable even after a full day of use. For eyeglass wearers, a long 15mm eye relief means you dont have to take your glasses off to see the full field of view these binoculars provide.
