Omegon Finderscope to T-Adapter turns your standard 50 mm viewfinder into a compact guidescope in no time. Simply remove the eyepiece from the viewfinder and mount this adapter. You then easily connect a guiding camera or accessory with T2 thread (M42x0.75).
The adapter is made of black anodized aluminum and fits most 8×50 and 9×50 viewfinders from Omegon, Sky-Watcher, TS Optics, Orion USA and older Celestron 50 mm models. Its sturdy construction keeps your camera securely attached and allows you to accurately focus via the knurled ring on the viewfinder lens.
Application
This adapter is ideal for astrophotographers who want to convert their existing 50 mm viewfinder into a full guidescope. Suitable for use with T2 cameras or in combination with additional accessories such as eyepiece clamps, rotary focusers and extensions. This allows flexible switching between guiding and visual applications.
