1.25" star diagonal with 99% reflection, dielectric coating, L/10 PtV

 

The Castell star diagonal has dielectric coating, providing 99% reflectivity with much longer lifetime than normal or enhanced coatings. The mirror surface has only L/10 ptv error, which is really smooth, resulting in excellent image quality. The brass compression ring protects the eyepieces.

 

The advantages in a nutshell

  • 1.25" mirror star diagonal directs the image 90° upwards - suitable for refractors, Maksutovs and SC telescopes
  • for a better image - suitable as a replacement for a standard star diagonal
  • 99% reflection - provides about 10% brighter images than an ordinary mirror
  • elegant design for better look

 

For all 1.25" focusers

You can use this mirror star diagonal on any refractor, Maksutov or SC telescope which has a 1.25" focuser. The Castell star diagonal deflects the image 90° upwards to provide you with a comfortable viewing angle.

 

For all 1.25" eyepieces

Whether Ploessl or wide angle - this mirror star diagonal can take any 1.25" eyepiece. Compression spring ring clamping holds the eyepiece barrel in an optimal grip for any observing orientation.

 

Brighter images - mirror with 99% reflection

You can look forward to a bright and sharp image, with inconspicuous details or faint nebulae now seen even better. The reason - a mirror with multiple microscopically-thin deposited dielectric mirror layers achieving 99% reflection. That means - some 10 percent more light than the mirror diagonals that typically come as accessories with most telescopes.
