Features:
1.Super clear astronomical telescope
With a focal length of 400 mm and an aperture of 70 mm, it can capture a clearer image, and is
coated with optical glass to enhance image brightness and protect your eyes. Excellent tools will help beginners and students explore the space.
2.Real HD vision
The BAK-4 prism provides brighter edges, a higher refractive index, and a round exit pupil in the field of view. This means that more light is transmitted through the entire field of view. The fully coated glass optical component is covered with a high transmittance coating, so the displayed image is as bright and clear as possible, with a total light transmittance of 99%.
3.High magnification
Equipped with two interchangeable eyepieces and a 3x Barlow lens. Eyepiece 1: 25 mm (16X), eyepiece 2: 10 mm (40X). The 3x Barlow lens triples the magnification of each eyepiece. The 5x24 viewfinder oscilloscope has a mounting bracket and crosshairs to easily find the object.
4.70mm large objective lens
Our refraction astronomical telescope is equipped with a 70 mm large-aperture objective. Compared with the 50 mm model, it provides a brighter and brighter field of view with little extra weight. Setting up and using Travel Scope is quick and easy.
5.Adjustable tripod and phone holder
This reflective astronomical telescope can be adjusted with aluminum alloy tripod and bag, allowing different observation positions, and the telescope and tripod are installed in the bag for easy travel and storage.
