Omegon 1.25″ projection adapter
Want to photograph through a telescope using the eyepiece projection method and looking for a reliable adapter to connect everything simply? The Omegon 1.25″ projection adapter is exactly what you need. This compact yet thoughtfully designed accessory bridges your telescope eyepiece and a T2-threaded camera - without unnecessary compromises.
How it works
The adapter slides into the telescope's focuser or star diagonal using a standard 1.25″ barrel. Inside, a clamping mechanism holds a 1.25″ eyepiece securely in place. The design also accommodates eyepieces with a wider body, which is especially useful when working with wide-field or ergonomic eyepieces with a larger outer diameter.
On the output side, a T2 thread allows direct connection of a DSLR or mirrorless camera via a T2 ring (T-adapter) matched to your specific camera mount. The eyepiece projection method makes it possible to achieve very high effective magnification - the focal length of the resulting optical system increases significantly depending on the eyepiece used and the distance between the eyepiece and the camera sensor.
Eyepiece projection - ideal for lunar and planetary photography
Eyepiece projection is a popular technique especially when photographing the Moon, planets, or solar details (with an appropriate filter), where high magnification is desirable without the need to invest in expensive teleconverters. Choosing the right eyepiece and achieving precise focus are key factors - and the solid, stable construction of this adapter minimizes unwanted vibrations and inaccuracies.
Compact dimensions, ready for the field
With an optical length of 64 mm and overall dimensions of 44.5 x 44.5 x 93 mm, the adapter is a compact and easily portable accessory that takes up almost no space in your bag. At the same time, it is a fully capable tool ready for demanding use in the field as well as careful work at an observatory.
What you need for a complete setup
To assemble the full system, you will need - in addition to this adapter and an eyepiece - a T2 ring matching your camera mount. Compatible mounts include:
- Canon EF
- Nikon F
- Sony E
- and other common bayonet mounts
The complete eyepiece projection system is then ready to use within seconds, with no additional modifications or special tools required.
