TeleVue Zenith Mirror 90° 1.25″ – Diagonal Mirror
The TeleVue Zenith Mirror 90° 1.25" is a high-quality diagonal mirror combines comfort and optical performance. Thanks to the 90° view Can you perceive relaxation, especially when looking at objects high in the sky.
A good telescope deserves a high-quality diagonal. A poorly made prism or mirror can limit the performance of your optics. TeleVue prevents such optical bottlenecks and ensures consistent image quality from objective to eyepiece.

96% reflection and precise finishing
This diagonal has a 96% reflective aluminum coating. This means a high light output and a bright, high-contrast image.
The housing is machined from a solid block aluminum and is subjected to strict quality controls. This ensures stable optical alignment and long-term reliability.
The 1.25″ telescopic connection and 1.25" eyepiece holder make it suitable for standard 1.25″ eyepieces. Thanks to the integrated retaining clip keeps the eyepiece securely and evenly in place. Additionally, there is a filter thread present for standard 1.25" filters.
The mirror provides an upright image, but left and right remain reversed – as is usual with an astronomical diagonal.
