• Doublet elements, air-spaced apochromatic: The objective lens includes a Super ED glass element, offering superior performance compared to standard ED glass. This design achieves outstanding sharpness and color fidelity while effectively mitigating chromatic aberration and spherical aberration, ensuring exceptional image quality for precise observations.

• Superior Waterproof Performance: The giant binoculars (excluding the eyepiece section) is rated IPX7, offering waterproof capability to withstand immersion in 1 meter of water for up to 30 minutes, making it suitable for challenging high-humidity environments.

• Comfortable Observation: Selected models offer 45° and 90° versions, allowing users to choose based on their primary observation needs. This design reduces neck strain during extended viewing sessions, with both versions providing the same high optical performance.

 

>>>>>APO ZOOM BINO Series: Variable Magnification, Multipurpose Utility

The APO ZOOM BINO series is an innovative series with adjustable magnification, designed for users who require flexible zoom capabilities and superior waterproof performance. Ideal for outdoor observations, it is well-suited to withstand harsh environments.

Models：

• 70 APO ZOOM BINO, 82 APO ZOOM BINO-TBD

• Doublet elements, air-spaced apochromatic;The objective lens includes a Super ED glass element, it delivers exceptional image sharpness and color accuracy while effectively minimizing chromatic and spherical aberrations, making it ideal for detailed observations.

• Adjustable Magnification: This series allows magnification adjustments at the eyepiece side, enabling users to adapt flexibly to different observation targets as needed.

• Constant Apparent FOV: Compared to conventional zoom eyepieces, this product features a 66° constant apparent field of view. During magnification adjustments, the field stop remains unchanged, eliminating the variation in field size common with standard zoom eyepieces. This provides a more comfortable and immersive viewing experience..

• Superior Waterproof Performance: Including the eyepiece focus and zoom components, are rated IPX7 waterproof. They can withstand immersion in 1 meter of water for 30 minutes, ensuring reliable performance in high-humidity environments.

• Lightweight and Portable: Designed for convenience, it is easy to carry and ideal for outdoor use.

Q&A

Q 1. What is the difference between ED glass and Super ED glass?

A: ED Glass (Extra-Low Dispersion Glass): This is a type of fluorite-based glass with low dispersion, featuring an Abbe number of around 81.6. When combined with other optical glasses through proper design, it can significantly reduce chromatic aberration, delivering sharper and clearer images.

Super ED Glass: A premium category within ED glasses, it boasts an Abbe number of 95 or higher, approaching the performance of fluorite crystals. It offers exceptional ultra-low dispersion properties and superior chromatic aberration control, making it ideal for observation needs requiring the highest image quality.

Summary: Super ED glass provides better chromatic aberration control than standard ED glass, making it the preferred choice for users seeking the ultimate in image quality.

Q2: What are the differences between the GIANT BINO, ED BINO, and APO BINO series?

A: GIANT BINO Series: Features achromatic correction using high-quality optical glass, suitable for basic observations. The exit diaphragm differs from that of the other series.

ED BINO Series: including one ED (Extra-Low Dispersion) glass element in the objective lens, significantly reducing chromatic aberration compared to the Achromatic Series. This provides clearer and sharper images. The exit diaphragm also differs from the other series.

APO BINO Series: including one Super ED glass element in the objective lens, further reducing residual chromatic and spherical aberrations compared to the ED Series. It delivers exceptional sharpness, color fidelity, and the best overall image quality.

Selection Advice: Choose based on your budget, observation targets, and commonly used magnifications.

Q3: Too Many Giant Binoculars—How Should I Choose?
A: Choose Based on Purpose and Budget:

• Primarily for Astronomy: Opt for the 90° version. Select based on your budget and desired performance.
• Primarily for Nature Observation: Opt for the 45° version. Select based on your budget and desired performance.

Q4: Can I Change the Eyepieces?

A: Absolutely, but please keep the following in mind:

SR giant binoculars use a highly compatible astronomical 1.25-inch interface (2-inch interface for 150mm models). However, due to the lack of center coaxial alignment in most astronomical eyepieces and potential interface tolerances, some eyepieces may not perform optimally or may not fit into the focuser.

SR guarantees the optical performance of the eyepieces supplied with the binoculars but cannot ensure the same performance for third-party eyepieces.

Q5: Can I Purchase the Hard Case Separately?
A: Currently, we provide hard cases for the 100APO BINO, 120APO BINO, 150APO BINO, and 150 ED BINO models. For models without a hard case included, you can contact us to purchase one separately, ensuring better protection for your equipment.

Q6: What should I do if there is an issue with the optical alignment?

A: 1.Contact SR or an authorized dealer to seek professional optical alignment services.

2.If the issue cannot be resolved, we recommend sending the product back for factory repair to ensure optimal performance.
