This is a straight through version of the F80M2. Now you can use a finderscope in conjunction with auto guiders or mount a Nagler 22 to the telescope for stunning wide field views. This finder provides a straight through inverted image only. It will not work with a diagonal. The 2" helical focuser has a 1.25" adapter and our E3023R crosshair eyepiece that works with optional illuminators. For a true porthole view of the sky, use our 2" 26mm 68 degree crosshair reticle eyepiece.
NOTE: This is the finderscope only. Visit our 80 mm mounting rings page to select the ring system you will need to mount this finderscope to your particular telescope.
