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.
Important! When installing mounting rings DO NOT unscrew the dew shield. The objective may fall out. Always unscrew the rear assembly (adapter, prism, focuser, eyepiece) from the main tube to install the rings.
*Rear thread size for all F080 models is M82 x 1mm
