About this item

  • 90 DEGREE ANGLE: This 90 degree diagonal mirror works with refracting telescopes to hold the image upright, albeit upside down from side to side, without interfering with astronomical observations.
  • EASY INSTALLATION: This mirror is easy to install and use. Simply insert one end into the 0.965 inch telescope and screw the other end to fix the 1.25 inch eyepiece.
  • FULLY COATED LENS: lenses are equipped with fully coated lenses with a dust cover to keep the lenses clean and make viewing images clearer.
  • MULTIFUNCTIONAL APPLICATION: This diagonal mirror is for celestial observation and can also be used for terrestrial observation. By using the mirror, users can easily observe the sky or the ground.
  • APPLICATION: This mirror is suitable for 1.25 inch eyepieces and 0.965 inch telescope focusers. Designed for refracting telescopes, not for reflecting telescopes.

High quality reflectivity. 1 1/4 inch eyepiece fit in it and it has a compression ring. I can't tell about the .965 fit as it is for a friend who I gifted my old Tasco telescope to years ago. I was surprised about the considerable size difference between 1 1/4 and .965 as it doesn't sound like a lot.
