## Long description

The DIELECTRIC mirror bevel socket DO-GSO 90° 2" STD201 is a precision optical accessory designed for telescopes, offering a comfortable 90-degree viewing angle for astronomical observations.
Advantages
This dielectric mirror bevel socket significantly enhances optical performance by utilizing a high-reflectivity dielectric coating that maximizes light transmission and ensures brighter, clearer images. Built for durability and precision, it serves as a reliable upgrade for various telescope configurations, reducing neck strain during long viewing sessions by positioning the eyepiece at a right angle.
Suitable for
Amateur and advanced astronomers upgrading their telescope setups
Observing the Moon, planets, and deep-sky objects with increased image brightness
Improving viewing ergonomics during extended night sky observation sessions
When it may not be suitable
This product may not be suitable for telescope optical systems that require specific backfocus distances that cannot accommodate a 2-inch star diagonal. It is also not designed for terrestrial viewing setups where an upright, correct-image erecting prism is strictly required.
Key specifications
Accessory type: Dielectric mirror bevel socket / star diagonal
Viewing angle: 90 degrees
Barrel size: 2 inches
Coating: High-reflectivity dielectric coating
How to use
Insert the 2-inch barrel of the dielectric mirror bevel socket securely into the telescope's focuser and lock it in place using the thumbscrews. Next, insert your compatible 2-inch telescope eyepiece or adapter into the socket receiver and secure it firmly. Adjust the telescope focuser until a sharp and clear image is achieved.
What to consider before purchase
Ensure your telescope focuser is compatible with 2-inch accessories
Check available backfocus travel to confirm the diagonal will reach focus
Verify that your observational goals align with a 90-degree standard mirror diagonal
Make sure to store the mirror socket in a dry, dust-free environment with protective caps attached when not in use, and clean the optical surfaces only with specialized optical cleaning tools to preserve the dielectric coating.
