Design
At the heart of the Founder Optics FOT016 is premium performance 3-element ED APO triplet refractor, designed by a famous optical designer in based in Japan. The optical performance is impressive as a two ED glass elements are employed.
Unlike most ED triplet telescopes which use only 1 ED glass element, Founder Optics adopted 2 ED glass of S-FPL 53 and S-FPL 51 to bring a remarkable image that you'll immediately spot with even a casual viewing. With two fluoro-crown ED glass elements and fully multi-coated optics, these Founder Optics refractors provide a crystal clear, superb sharp, zero aberration and distortion image to your eyes or camera sensor.
In addition, each element is fully separated or air spaced which is not common even among APO triplet telescopes. This offers further improvements to the already impressive optical quality.
Quality
In order to complete this unique design, it requires a very high level machining and assembly capability. Founder Optics partner with an experienced factory located in Taiwan with over 50 years experience in precision manufacturing, especially for Japanese companies.
Besides manufacturing know-how, the high standard of quality control is also crucial to producing FOT86 and FOT106 telescopes. This is recorded in a Quality Certification Card.
Every unit is thoroughly tested, and these unique records help customers understand the quality of their telescope. Founder Optics take their quality checking very seriously as they aim to offer the best triplet APO telescopes to BINTEL customers.
Focuser - 2.7'' Rack & Pinion
Perfect Hybrid Drive system with 8 Ball bearings- More Smoothly!
2sets of 4pcs ball bearing at 2 sides between the drawtube and the focuser handle linear travel of the focuser. Once the locked the knob, there is no gap among the drawtube, 8pcs ball bearings, and the focuser cover. It does not only keep the focuser always paralleled the optic axis, but also keep it moved very smoothly.
Dual Speed Focuser- 1:11 – Extremely Accurate!
Smooth focus motion and fine focus wheel allow precision adjustment from critical focusing of eyepiece or camera.
Unique Lock Function– Heavy Loading Capability!
Special lock grabs the rack& pinion & drawtube in two directions. The design makes the focuser always paralleled the optics axis. Instead of pushing against the drawtube to eliminate focus shift while it’s focused. And it can handle up to 8kg as well for complex imaging trains.
Longer Traveling Distance– Suitable for a range of Photographing Accessories!
Unlike other focusers, the long travel 95mm provides more room for adjust for fine and accurate focus.
It is compatibly for a wide range of photographic accessories, along with easy to use controls.
Focuser Rotator Function
Flexible rotated structure provides a convenience for user to have the best position to adjust focuser when observation and photography. The precision machining parts and assembly technique make a good collimation even rotate the focuser and rotator.
Loosen the rotator knob and focuser knob to rotate the focuser and rotator.
Solid, lockable Dew Shield
Built in sliding dew shield. Three screws hold dew shield stable while imaging or observing while keeping it place during transport.
