Product description
Since the magnification is lower than that of ordinary binoculars and monoculars, it is possible to observe a wide range of stars. With a low magnification and an objective lens with a diameter of 48 mm, it is possible to observe even darker stars than you can see with the naked eye.
We adopted a robust aluminum solid by CNC processing. It holds the optical axis firmly and enables comfortable observation.
Comes with a 48mm filter thread. Since a filter thread of φ48 mm (P = 0.75) is attached to the objective lens side, it is possible to attach a commercially available astronomical filter.
Since the magnification is 3 times, it can be used for watching plays, watching sports, concerts, etc. It is very bright and has a wide field of view, and there is little camera shake, so you can use it comfortably.
A multilayer coating is applied to all air contact surfaces of the lens. A bright field of view is achieved by minimizing the loss of light due to reflection on the lens surface.
A special semi-hard case is attached so that it can be carried around.
* There is a possibility that infinity may not come out depending on your eyesight. We recommend viewing with a visual acuity of 1.0 or higher.
Multi-coat is used on the entire surface of the lens
Multi-coating is used for all parts of the lens that come into contact with the air. By increasing the light transmittance, it can be used in dark places.
Case is also included
A special semi-hard case is also included. If you carry it in a semi-hard case, it will prevent the main body from being scratched and you can carry it with confidence.
Bright with a lens diameter of 48 mm
Compared to small binoculars, the lens is larger and you can see with clearer and brighter image quality. You can see it for various purposes such as watching a play as well as the starry sky.
The eyepiece lens is also large
Since the lens on the eyepiece side is also large, it is easy to match with the eyes and it is very easy to see.
Magnification is 3 times
Since the magnification is as low as 3 times, the field of view is wide and there is little camera shake, so you can see stably.
Palm-sized and small
The body itself is palm-sized and very small, and the body weighs only 380g, making it a light opera glass.
