Perfect All-Rounder - Long Perng ED 85mm, f/6.6, F560mm, Triplet refractor
Featuring two ED glass elements for remarkable true-color performance, the Long Perng Triplet Apo Refractor is an absolute perfect centerpiece of any star-hunters arsenal. A quality import from Taiwan that has been tested and approved by Farpoint.
Unlike most ED triplets which are made with just one ED glass element, this beautifully crafted apochromatic refractor stands above ordinary triplets since it features one element of FPL-53 ED glass and one element of FPL-51 ED glass. With its two fluoro-crown ED glass elements and fully multi-coated optics, the Orion EON 85mm ED-X2 refractor provides superior correction of chromatic and spherical aberrations.
The Long Perng Triplet refractor measures 560mm in focal length with a fast f/6.6 focal ratio which is excellent for wide-field visual and photographic use. Multiple internal baffles prevent off-axis reflections for excellent contrast, while a retractable lens shade helps eliminate glare and dew buildup.
The Long Perng Triplet sports a hybrid-drive 2" rack and pinion focuser which can support imaging gear trains weighing up to 17.6 lbs., and features dual-speed (11:1) controls to easily fine-tune focus. You can rotate the focuser 360-deg to optimize imaging or observing convenience. The focuser permits 60mm of backfocus travel, and has a built-in focus lock knob. A step-down 1.25 inch adapter is included.
The Long Perng Triplet f/6.6 Triplet Apo Refractor comes with a thread-on objective lens cover, two heavy-duty machined tube rings, a sturdy machined dovetail bar for easy mount attachment, and a dovetail finder scope base (installation required). An included hard carry case with a custom die-cut foam insert ensures safe transport and convenient storage.
