Choose a telescope, camera or combination to preview how large near and deep space objects will appear and whether the sampling is good for astrophotography. It’s easy! You can also enter in the specifications for any items that aren’t listed.
The Pentax PF-80ED-A Spotting Scope is a large and impressive optical performer, with a brilliant 80mm objective lens and the ability to accept any 1.25″ astronomy eyepiece as well as 82mm filters at the front of the objective. It is 100% waterproof and fogproof, with durable rubber armor over an all-metal housing that’s got a rotating tripod collar with click stops every 45°. 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 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.
Please note this spotting scope does not come standard with an eyepiece. A good suggestion would be:
