I am still a newbie when it comes to Astronomy. However, even my untrained eyes can notice the differences in cheaper telescope eyepieces. That is why I only buy Tele Vue Eyepieces now. Aside from this Tele Vue 1.25: 90 Degree Everbrite Diagonal, I also own several Tele View Eyepieces; 32mm Plossl, 31mm Nagler Type 5, 27mm Panoptic, 24mm Panoptic, 22mm Nagler Type 4, 18.2mm DeLite, 17mm Nagler Type 4, 13mm DeLite, 13mm Ethos, 10mm Radian, 10mm Ethos, 7mm DeLite, 6mm Ethos, 1.25 inch 2x Barlow and a Tele Vue 2 inch 2x Powermate.

For astrophotography enthusiasts and stargazers seeking superior optical performance, the 1.25" 90 Degree Everbrite Diagonal with Brass Clamp Ring is an exceptional choice. This high-quality diagonal is designed to deliver whiter, brighter, and more natural images, thanks to its Everbrite mirror coating. This unique, dielectric, nonmetallic coating boasts a remarkable 99% reflectivity across the full visual spectrum, ensuring the most vivid and true-to-life viewing experience.
The Everbrite coating is meticulously applied to Pyrex, a material known for its durability and precision, with a surface accuracy of a 1/10 wave flatness. This guarantees a flawless reflection of light, enhancing the quality of the image you see through your telescope.
The 1.25" 90 Degree Everbrite Diagonal is crafted from a solid block of aluminum, ensuring robustness and longevity. This one-piece body construction not only guarantees permanent alignment but also prevents heavy accessories from causing the diagonal body to unscrew from the barrel - a common issue with other brands.
This model also features a brass clamp ring, which provides a secure and stable connection to your telescope. The anti-reflection threads minimize unwanted light interference, while the 1.25" filter threads allow for the attachment of various filters to enhance your viewing experience.
In summary, the 1.25" 90 Degree Everbrite Diagonal with Brass Clamp Ring is an excellent investment for those seeking to elevate their stargazing or astrophotography experience with superior optical performance.
