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!

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.

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.

The optical design prioritizes optimal compactness, featuring thinner lens elements, reduced lens diameter and minimized spacing between lenses. The magnesium housing ensures durability while keeping the weight low, allowing for comfortable, long-term use without fatigue.

Lighter and more compact - how?

The SFL range has become a favourite with bird watchers and nature fans since their launch. Now the SFL 50 delivers viewing normally found in larger optics, but in a smaller size body. 

The ZEISS SFL is shorter and more compact than many other other premium binoculars due to:

Thinner lens elements

Smart design reduces the distance between optical components

Schmidt-Pechan prism design reduces the size while maintaining optical performance

Experience nature in all its splendour

The Ultra-High-Definition (UHD) concept features a special coating and an improved optical design that ensures the binoculars deliver the highest level of detail and reproduce colours with natural fidelity. This makes it possible to precisely identify the smallest features in the plumage and reliably distinguish between species. 

High Performance Optics with UHD Concept

• Large entrance & exit pupils combined with 90 % light transmission ensure bright viewing experience especially in low light conditions
• True-to-life colours provide exceptional colour fidelity for accurate identification of wildlife
• Wide Field of View making it easier to track moving subjects
• Close Focusing Distance of just 1.8 m allows detailed observation of nearby targets.

Bright images even in low light

With 90% light transmission, their large entrance pupil of 50 mm and the ZEISS T* multi-layer coating, you can clearly and precisely see details even in low-light situations and at dusk.

Waterproof, fogproof and UV resistant - perfect for Australian conditions

• Natural rubber armouring material, a NRB compound which is Latex-free and PAH compliant
• Water repellent ZEISS LotuTec lens coating ensures that water beads off without residue immediately, and that dirt and fingerprints do not adhere to the surface. 

Perfect Ergonomics

• SmartFocus Concept features a large focus wheel positioned for optimal accessibility, preventing over-stretching of the focusing finger
• Quick & Precise focusing for fast adjustments, even when wearing gloves
• Perfectly balanced in the hands, enabling long and steady observation
• Smooth and robust eyecups enhance comfort and usability

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.

测试和质量保证

TEC 望远镜经过严格测试，以确保顶级品质性能。整个玻璃生产过程中都使用牛顿环，然后我们使用干涉仪纠正任何剩余的缺陷。然后对每台望远镜进行严格测试，以达到最佳的斯特列尔比。请放心，您的望远镜已经过优化，光学性能尽可能完美。如果物镜没有达到 Yuri 的期望，望远镜将不会发货。作为一项严格政策，TEC 不会发布望远镜测试报告。

虽然物镜在干涉控制下经过微调以满足最高的光学标准，但物镜和镜筒组件中可能存在外观缺陷。请放心，望远镜中的任何缺陷均已确定不会影响光学性能。
