Astronomical Telescope 90 Deg Dielectric Mirror Diagonal with 1.25 inches Adapter

SVBONY 2" 90-Degree Dielectric Mirror Diagonal for Telescope

Enhance your celestial observations with the SVBONY 2" 90-Degree Dielectric Mirror Diagonal, designed to provide exceptional optical clarity and durability for your telescope setup. This premium accessory ensures a comfortable 90-degree viewing angle from your refractor, compatible with standard 2" (50.8 mm) diameter focus tubes. Whether you're using 2" or 1.25" (31.75 mm) eyepieces, this diagonal meets all your observational needs.

Key Features:

1. High-Quality Construction: Crafted from durable metal, the SVBONY diagonal mirror boasts a sleek, high-gloss finish that not only enhances its appearance but also guarantees longevity in use.

2. Dielectric Coating: Unlike standard aluminized diagonals, the dielectric coating on this mirror provides an impressive 99% reflectivity across the visible spectrum. This ensures minimal light loss and maintains consistent performance over time without the reflectivity degradation typical of aluminum surfaces.

3. Versatility: The diagonal includes a solid aluminum housing and is threaded to accept standard 2" filters, expanding your imaging capabilities by allowing the use of various optical accessories.

4. Eyepiece Compatibility: It features a dual eyepiece holder system with non-marring brass compression rings. This secures your valuable eyepieces without damaging them, accommodating both 2" and 1.25" eyepiece sizes seamlessly.

5. Optical Performance: The 1/10th wave flat optical glass surface ensures high-definition views, free from distortions or aberrations, making it ideal for detailed planetary and deep-sky observations.

Why Choose a Dielectric Diagonal?

Dielectric coatings offer superior performance over standard aluminum mirrors. While traditional aluminized diagonals degrade in reflectivity over time, typically starting at 92%, dielectric coatings maintain near-perfect reflectivity of 99% throughout their lifespan. This translates to enhanced light grasp and sharper, more detailed views of celestial objects, especially in low-light conditions.

In conclusion, the SVBONY 2" 90-Degree Dielectric Mirror Diagonal is a must-have accessory for any serious astronomer seeking uncompromising optical quality and versatility in their telescope setup. Its robust construction, advanced optical coatings, and compatibility features ensure years of enjoyable and high-definition stargazing experiences.
