Design

At the heart of the Founder Optics FOT86 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'' 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!

Not Designed for Immediate Observation at All Angles

The eyepiece is angled at 45 degrees, allowing for comfortable and casual stargazing—but not instant viewing from every position.

Recommended Stable Setup

For the BT81S-A optical tube, we recommend combining it with the HF2 fork mount and a ladder-type table with a free-stop mechanism, along with the highly rigid SXG-HAL130 tripod. This setup provides excellent stability for smooth and reliable observations.

Take your stargazing to the next level with the Bintel Beginner Telescope Upgrade Kit, designed to enhance your lunar observations. The Moon has long been the first celestial target for astronomers, both amateur and experienced. Its proximity and striking beauty make it an inviting object to observe, often sparking the curiosity of those new to stargazing. With its craters, plains, and fascinating features, the Moon is an accessible and captivating starting point for anyone exploring the night sky. This essential kit includes two items that will transform your experience of the Moon: the Celestron Observer's Map of the Moon and the Orion Moon Map 260.

Orion Moon Map 260

Embark on a guided lunar adventure with the Orion Moon Map 260, a must-have for any backyard astronomer. This meticulously detailed map identifies over 260 lunar features, including craters, valleys, mountain ranges, ancient lava flows, and the successful landing sites of both US and Soviet lunar missions. The map offers two viewing perspectives: a correct-image view for standard observations, and a reversed (mirror image) view for easy use with binoculars or telescopes.

The map’s laminated design ensures it’s durable and weather-resistant, providing protection against dew, dirt, and the elements. It measures 64.5 cm x 27.9 cm when unfolded and folds to a portable 21.6 cm x 27.9 cm size. On the map, each lunar feature is cross-referenced by number, size, and description, making it easy to identify fascinating areas on the Moon’s surface. Whether you’re a seasoned astronomer or a beginner, the Orion Moon Map 260 is the perfect companion to guide your lunar observations, whether you're at home or on the go.

Bintel Moon Filter
Viewing the Moon through a telescope can often be overwhelming due to its intense brightness, which can obscure fine details. The Bintel Moon Filter reduces the Moon’s glare, allowing your eyes to relax and revealing more intricate features with greater clarity. Perfect for near-full Moon observations, this filter screws onto most 1.25” eyepieces in just seconds and enhances your overall lunar experience. It’s not only great for the Moon but also helps when observing bright planets like Venus or terrestrial scenes. (Note: this filter is not suitable for solar viewing.)

This kit is the perfect upgrade for anyone looking to enhance their lunar observations. With the Orion Moon Map 260 to guide your exploration and the Bintel Moon Filter to improve clarity, you'll be able to experience the Moon in a whole new way. It’s an ideal addition to your telescope setup, ensuring more detailed and enjoyable lunar views with every session.

Premium Optics with HD Concept

The optical excellence of the Conquest HDX is based on the HD concept: a perfectly balanced optical system that combines selected coatings, lenses and a finely tuned optical design. It enables 90 % light transmission for the brightest images, color fidelity for true-to-life images without color fringing and color casts for perfect identification and sharpness from edge to edge for a clear and detailed image across the entire field-of-view.

Robust and durable design

The Conquest HDX is built to last in any environment, whether it's extreme temperatures, wet conditions, or direct sunlight. Its durable, waterproof, and shockproof features are attributed to its robust mechanical design and lightweight magnesium housing. Additionally, it's covered with a protective rubber armoring that provides a perfect grip under any circumstances.

Carefully thought-out ergonomics

The carefully thought-out ergonomics enable comfortable handling during longer periods of observation thanks to the non-slip grip and the smooth and precise focusing wheel. Adjustable eyecups and lockable diopter settings ensure a customized viewing experience.

A clear view, whatever the weather

There are always exciting things to be seen in the world of nature – even in wet weather. This is why ZEISS developed LotuTec®. A coating for the lenses of binoculars and spotting scopes that enables a clear and unhindered view in all weather conditions.

ZEISS T* Coating

ZEISS T* coating is a guarantee of the brilliant, high-contrast images­­ which you will experience above all in adverse light conditions and in the twilight. Behind it, however, there is no specific formula for building up the layers. Instead, it is a technology that is constantly adjusted to suit new glass materials and requirements, which varies from lens to lens.
