An exellent price/performance binoviewer. Stereoscopic view from a common 1-1/4" focuser (or a 2" one with an adapter), and sporting a nice generous 20mm clear aperture for maximum light entry and FOV. Accepts standard thread color filters and Barlows as well ("Shorty" prefered to reduce overhung weight). Uses a pair of standard 1.25" changeable occulars (not included). Plossl is commonly used however much wider angle viewing is possible and often prefered for that "Wow" factor. These should be of a good brand and parfocal, such as several shown on our NightFire "Everything-Ocular" page. Here again, NightFire does not just "jump-on" a low price bandwagon like everyone else... we search the best price vs. performance ratio... so these also have BAK4 Prisms, variable inter-pupilary-distance 52-75mm, and helical focus-matching with screw clamps of course. Aluminum case.  NFV01  -  $231.75 USD
