TS-Optics 80 mm right-angle finder scope with 90° Amici prism and 1.25" helical focuser The TSFRE80 ist far more than a finder, it is a full-fledged wide field refractor. Many hundreds of deep sky objects are already visible through this super finder. It truly deserves this name, as finding celestial objects is really easy.
Of course, application is very versatile. Besides the use as ultimate finder, the refractor can also be used as travel telescope and as spotting scope for observing the countryside. You can use many 1.25 eyepieces and thus vary the magnification in a wide range. But the finder can also be used as guiding scope, together with specific autoguiders.
The advantages - Quality processing of metal for maximum stability
- Good 2-element lens, multi-coated
- Focusing by rotating the eyepiece side of the 1.25" helical focuser
- Solid clamping through compression ring
- Upright and non-mirrored image through the 90° Amici prism

Eyepieces and autoguiders The focus of the finder is approx. 5 mm above the 1.25" receptacle of the focuser. That is enough for many eyepieces like Plössl eyepieces.
The finder is also suitable for autoguiding, but the autoguider must have a 1.25" housing, otherwise you will not reach the focus.
