STELLARUE 9X50 STRAIGHT-TROUGH FINDERSCOPE

The STELLARUE 9X50 STRAIGHT-TROUGH FINDERSCOPE includes our E3023R reticle eyepiece so it can be used visually “out of the box”. This finderscope weighs 18 ounces and works with all of our standard 50 mm ring systems. The STELLARUE 9X50 STRAIGHT-TROUGH FINDERSCOPE employs a high quality 210 mm focal length, broadband fully multi-coated objective lens as in our top rated F50M2 finderscopes. Other fittings are black anodized. Main tube is interior painted in ultra flat black. Focuser is lubricated for improved stability and smoothness. Tube is 54.5 mm in diameter, dew shield is about 58 mm in diameter. The length is 9 1/4” – 9 3/4”.

The STELLARUE 9X50 STRAIGHT-TROUGH FINDERSCOPE can also be used as a guide scope. It features a 1.25″ non-rotating helical focuser and a standard 1.25″ compression ring unit with an external M42 X .75 t-thread. So one can either use the camera’s t-thread or a 1.25″ nosepiece. The F050M3 fits on either our 50-60 mm finderscope rings or our 50-60 mm guidescope dual ring systems.

Some guide cameras have a very short backfocus distance. If you cannot attain focus with your guide camera and need to focus beyond the maximum extension, you may purchase additional STE52 extension tubes to increase the distance between the focuser and objective lens.
