Binorum SuperStrong T2 (Female) / 1.25″ Adapter
The Binorum SuperStrong T2/1.25″ adapter is a precision-machined reducer that connects 1.25″ eyepieces and accessories directly to the T2 thread of a telescope or focuser. Its compact size and simple installation make it a practical tool for both visual observing and astrophotography. If you regularly combine different optical components, this adapter will quickly become an essential part of your kit.
Secure hold, no scratches
On the eyepiece side, the adapter features a brass compression ring that holds accessories firmly and safely - with no risk of scratching or accidental slippage. Three locking screws add extra security, preventing rotation or ejection of the accessory even during fieldwork. The entire adapter has a quality black anodised finish, which eliminates unwanted reflections inside the optical path and protects the surface against corrosion during long-term use.
More than just a basic adapter
The adapter accepts any standard 1.25″ accessory through the brass compression ring. In addition, it features an external T2 thread on the eyepiece side. This lets you attach T2 extension tubes, filters, or other T2 accessories, significantly expanding your options without the need for additional reducers.
Eyepiece projection - detailed planetary images at high magnification
Eyepiece projection is one of the most rewarding methods of astronomical photography through a telescope. It places an eyepiece in the optical path between the telescope and the camera to increase the final magnification. This adapter fully supports the technique - simply attach a T2 extension tube and insert the desired eyepiece. The result is detailed images of planets, the Moon, or double stars captured at high magnification with no compromise in image quality.
Compatible with most telescopes
The T2 to 1.25″ adapter works with the majority of modern and older telescopes fitted with a standard T2 thread - whether refractors, reflectors, or catadioptric designs from various manufacturers. The solid metal construction and precisely machined threads ensure reliable, repeatable use without any loss of centring accuracy. The adapter maintains its performance even after years of regular use under night-sky conditions.
A versatile addition to your astronomy kit
If you are looking for a flexible way to expand your telescope's capabilities and connect standard 1.25″ accessories, the Binorum SuperStrong T2/1.25″ is a well-thought-out and practical choice. The combination of robust construction, a brass compression ring, and an additional T2 thread makes it one of the most versatile adapters in the range of astronomy accessories.
