TS Optics 50mm angle finder with upright and right-sided image
The TSFRE50 is more than just a viewfinder. The good 2-element lens with 50mm diameter already shows many hundreds of deep-sky objects in combination with the illuminated crosshair eyepiece TSIR20. But also as a guide tube with special autoguiders the viewfinder can be used.

The advantages and product features of the TSFRE50:

• High-quality metal processing for the best possible stability
• Good 2-element lens with multi-coating
• Focusing by turning the 1.25" helical excerpt on the eyepiece side
• Solid clamping by ring clamping
• Upright and right-sided image through the 90° amiciprisma
• The viewing position can be rotated in the desired direction
• The adjustable clamps have metal screws with a plastic tip to prevent scratches on the telescope
• The viewfinder fits in standard viewfinder brackets as used by Sky-Watcher, Celestron, GSO ...

 

Suitable eyepieces and autoguiders for the TSFRE50:

The focus of the viewfinder is about 5 mm above the 1.25" socket of the focuser, which is sufficient for many eyepieces, such as Plossel eyepieces A very nice eyepiece for centering is the illuminated crosshair eyepiece TSIR20 (see accessories).

Also for autoguiding the viewfinder is suitable, however the autoguider must have a 1.25"-housing, otherwise you will not come in the focus. Suitable autoguiders are among other things:

• TSGPM120M - mono planet camera and autoguider
• Astrolumina ALCCD5-II
• SBIG STi
• Starlight Xpress Lodestar
