Key Features

• Dielectric Coatings for Optimal Light Transmission

  The dielectric coatings on the mirror surface ensure over 99% reflectivity, reducing light loss and providing bright, sharp images for enhanced astronomical viewing.

• Versatile Nosepiece Compatibility

  The 1.25-inch nosepiece fits 1.25-inch telescopes and accepts standard accessories such as filters, eyepieces, and Barlow lenses, while the 2-inch nosepiece works with 2-inch telescopes for larger accessories.

• 90-Degree Viewing Angle

  With a 90-degree angle, this mirror diagonal provides a comfortable, ergonomic viewing position, making it perfect for observing objects overhead during stargazing.

• Upright Image with Left/Right Reversal

  The diagonal corrects the upside-down image but reverses left and right, offering a natural view for most astronomical observations, perfect for planetary and lunar photography.

• Brass Compression Ring for Secure Fit

  Equipped with a brass compression ring and thumbscrew, the adapter ensures secure, scratch-free adjustments, preventing eyepiece rotation and protecting your gear during use.
