Datuson 5P9981C 2-inch to 1.25-inch interface Telescope Adapter for Astronomy Eyepieces & Accessories


The Datyson 5P9981C is a high-quality metal adapter designed to seamlessly connect telescope accessories across different barrel sizes. Manufactured in Jieyang, China, this precision-engineered component allows you to convert a 2-inch (50.8mm) interface down to a 1.25-inch (31.7mm) standard. Whether you are a professional astronomer or an amateur enthusiast, this adapter ensures a secure and stable connection for your eyepieces, cameras, and filters, making it an essential part of your astrophotography kit.


Key Features

🔩 Precision Machined Metal: Constructed from durable aluminum alloy, this adapter is built to withstand regular use in the field while maintaining a lightweight profile (Net Weight: 83g).

🔄 Standard Size Conversion: Effortlessly adapts equipment from a 2-inch (50.8mm outer diameter) interface down to a 1.25-inch (31.7mm inner diameter) receptacle.

📏 Standard M48 Threading: Features an M48 x 0.75mm internal thread, which is a standard specification for many telescopes, filter wheels, and astrophotography accessories.

⚫ Low Profile Design: With a flange distance of only 10mm, this adapter minimizes the optical path length, making it suitable for setups with limited back focus.

🖤 Anodized Finish: The black anodized surface helps reduce internal reflections and matches the aesthetic of most optical equipment.

Notes & Cautions

• Check interface type: Please ensure that your astronomical telescope uses a standard 2-inch interface before purchasing. This adapter is not compatible with interfaces of other sizes.

• Focuser Travel: When using adapters, be aware that the optical path length changes. Ensure your telescope's focuser has sufficient "inward" travel to achieve focus.

• Installation: Always tighten the adapter securely to prevent accessories from slipping, but avoid over-tightening to protect the threads.

• Storage: Keep the adapter in a dry environment to prevent oxidation of the metal surfaces.
