Feature of Alstar 1.25" 45-Degree Diagonal Prism Optical Prism


High Quality Prism Optical Material The prism is made of genuine optically processed glass; high quality optical prism inside rather than a mirror which makes your image clear and sharp. Compared with other glass materials, it greatly improves the transmission of transmitted light and enriches the saturation and contrast of image color.	Comfortable Observation with 45-degree It provides a comfortable object observation angle. The image you see through it is correct, which means that the image you see is vertical and correct from left to right. It's convenient to see the zenith of the sky. It's close to horizontal observation.	Made of Plastic and Metallic Aluminum The lens tubes on both sides are made of metal materials, and the middle connecting part is plastic, but it is still solid and durable, which reduces the weight of the product and the burden on the telescope to a certain extent. Eyepiece screws are clamping screws, which make the connection more firm, more stable and more convenient to use.


1.25Inch Standard Interface Size 1.25" 45-degree mirror star diagonal for any telescope with 1.25" connector (not suitable for Newtonians).	Free Dust Cover Two hard plastic dust covers are included in the package, which can effectively protect the lenses from damage and dirt when you are not using them.	Built-in Matt Thread The interference of stray light is effectively reduced, which not only improves the brightness of the image, but also effectively reduces the formation of dark edge and makes the edge details of the image clearer.

Cleaning and Storage

First, clean the surface with a dust removal balloon. This step is very important. After removing the hard dust on the surface, drop the special cleaning water for the lens (remember not to use glasses for night cleaning), and then use the special lens cleaning cloth or cotton swab to remove the surface cleaning liquid. After use, the two dust plugs (contained in the package) need to be installed back at both ends of the eyepiece to avoid direct sunlight, so as to prevent dust from entering the eyepiece and prolong the service life to the greatest extent.
