50MM large objective lens: the larger the exit pupil diameter and the larger the effective light-passing area, the higher the brightness of the field of view can be obtained. Even when observing under dim light conditions, it can ensure sufficient light flux, 7x magnification, (field of view) :116m/1000m)
Automatic fixed-focus system: The automatic fixed-focus system is good for tracking the trajectory of moving objects, observing the animal world, watching birds, watching the game, close in front of your eyes and clearly visible.
High-quality optical components: using BAK4, the refractive index is much larger than the general BAK7 can effectively avoid vignetting, FMC multi-layer broadband coating, the transmittance exceeds 90%
Nitrogen-filled, waterproof, dust-proof and fog-proof: special sealing technology, high polymer glue bonding at the interface of the lens body, to ensure that the internal nitrogen is not atomized or leaked, and can be floated to deal with various harsh environments and effectively extend the service life.
Humanized pupil design: The pupil distance range of the telescope is 60-70mm, which is generally suitable for most people. The foldable eye mask design is suitable for people who wear glasses and those who don’t wear glasses.
