1.25" Enhanced Aluminum Mirror Diagonal

by Orion
$119.99 CAD

Upgrade your telescope's optical performance with the Orion 1.25" Enhanced Aluminum Mirror Diagonal.  A mirror diagonal is an essential accessory for refractors or Schmidt-Cassegrain telescopes, allowing for comfortable viewing by adjusting the angle of the eyepiece while maintaining image clarity.  Unlike prism diagonals, mirror diagonals offer sharper and more accurate views, making them ideal for celestial observations.

This diagonal provides bright, clear images of stars, planets, and other astronomical objects.  It is not intended for terrestrial observing, as it inverts the image left-to-right, but it is perfect for astronomy enthusiasts who prioritize optical quality and precision.

Why Choose the Orion 1.25" Mirror Star Diagonal?

The Orion 1.25" Mirror Star Diagonal delivers exceptional optical performance thanks to its meticulously polished mirror, which provides sharp and contrast-rich views.  The anodized aluminum housing and internal blackening reduce glare and improve contrast.  Enhanced aluminum coatings provide 97% reflectivity, ensuring bright, clear images even in challenging viewing conditions.

Customer Reviews:

  • "Just What I Needed! Definitely a cut above the diagonal that came with my telescope.  Everything was so much clearer and sharper."

  • "Exceptional diagonal really makes a difference on objects seen compared to the stock eyepiece that comes with cheaper scopes.  Sharper, brighter images with better contrast."

  • "Nice. No color fringes, edge sharp and clear.  Not a huge increase in brightness with the enhanced aluminum, but a definite upgrade to the dime store diagonals."

These reviews highlight the Orion 1.25" Mirror Star Diagonal's improved clarity, sharpness, and brightness, making it an excellent choice for astronomy enthusiasts looking to upgrade their viewing experience.
