Kasai CS-Bino 3x50 Wide Field Binoculars

Kasai 3x50 mm Starry Sky ornamental binoculars CS-BINO

An enhanced version of the ultra-low magnification "constellation viewing" binoculars that show an exceptionally wide field of view of 17°

Small constellations such as Cassiopeia fit within one field of view, and even stars that are 2 to 2.5 magnitude fainter than the naked eye can be clearly seen, and you can enjoy a unique appearance as if the naked eye was doped.

The extremely wide actual field of view of 17° has an overwhelming sense of openness that could not be experienced with conventional binoculars, and it is possible to perform "features" such as checking the nebula clusters scattered in various places while looking at the entire view of the constellations.

Especially when you look at the starry places around the Milky Way, the beauty of the image is indescribable, and once you see this statue, you are guaranteed to be addicted to it. Of course, it shows a wide range of suitability for ground use, and when used for theater and landscape observation, you can enjoy a much wider field of view than ordinary opera glasses.

The left and right independent IF method is used for focusing. The shortest focusing distance is as short as about 2 m, so it is also suitable for viewing works in museums. By adopting a large eye lens with a diameter of 20 mm, you can see about 80% of the maximum field of view even while wearing glasses. This is a feature of this optics.

Broadband multi-coating is applied to the entire optical system to show high transmittance and high contrast image quality. The housing is all made of robust and lightweight aluminum alloy by CNC cutting. Kasai do not use any resin parts that are often found in inexpensive products.

The 285 g compact and lightweight body fits comfortably in your hand and can be easily carried anywhere.

A semi-hard case and strap that are convenient to carry are also included as standard.

These optics with a diameter of 5 cm and a magnification of 3x can see stars that are about 1 grade darker than shown by general constellation binoculars of about 2x in the 4 cm class, so it is recommended for those who are not satisfied with the previous models. is. Enjoy the myriad of stars scattered in the night sky with the greatly enhanced "enhanced" constellation binoculars.

Note 1: A Galilean telescope system has no eye-relief. The best way to see the widest field of view is to "press" your eyes as close as possible to the eyepieces. When wearing eyeglasses, the field of view may be reduced. With very strong eyeglass prescriptions with stronger than -6 diopter, it may not be possible to reach the infinity focus. In such cases, wearing contact lenses is recommended.

Note 2: The field of view of a Galilean telescope system varies by the eye pupil diameters of the observer. The full 17 degrees field of view can be obtained when the pupils are opened maximum (usually 7 mm). In brighter observing conditions or older observers, a smaller exit pupil will result in a reduced true field of view.
