Next: The JKT Acquisition and
Up: The Jacobus Kapteyn Telescope
The JKT has a 20cm refracting visual finder telescope with a focal
ratio of f/16.25. Depending on the eyepiece used, fields of 10, 30
and 90 arcmin may be viewed visually from the observing floor. The
finder is only used to diagnose gross pointing problems and for fun.
