Retractable hood shields objective from stray light or moisture
Accepts 82mm filters (Sold Separately)
The Pentax PF-80ED-A Spotting Scope has an 80mm objective lens and the ability to accept any 1.25" astronomy eyepiece (Sold Separately) as well as 82mm filters (Sold Separately) at the front of the objective. It is 100% waterproof and fogproof, with durable rubber armour over an all-metal housing that's got a rotating tripod collar with detented stops every 45 degrees. The fully multicoated optics feature Pentax's well-regarded SMC multicoating process, and an element of ED (extra-low dispersion) glass helps provide razor-sharp edge delineation to high-contrast subjects.
The PF-80ED-A's 1.25 diameter eyepiece specification allows less compacting of the light shaft produced by the objective lens, and thus a larger final image with superior depth perception. Any great 1.25" eyepiece (Sold Separatel) can be used, from Pentax themselves to elite telescope manufacturers' eyepieces such as Meade, Celestron, Vixen, and of course Tele Vue. The PF-80ED has a focal length of 518mm.
