Description

  • WIDE APPLICATION: It is suitable for various types of telescopes such as reflectors, refractors, for Dobsonians, for Mak Cas and for SCTs, and it is suitable for astronomical telescopes with an outer diameter of 84115mm, with a wide range of applications.
  • EASY MOUNTING: The mask is equipped with 3 bolts, which can be easily mounted on any telescope, making focusing easier and faster and providing the best focusing effect.
  • THREE METAL POST MOUNTING DESIGN: Three metal posts on the mask clamp the telescope to prevent slipping while keeping the mask perfectly centered. Thanks to this 3 post mount, the mask stays centered.Eliminates guesswork during focusing and even overcomes visual conditions to quickly and easily provide optimal focus for your telescope.
  • LIGHTWEIGHT DESIGN: The telescope focusing mask features a lightweight design with an aluminum alloy that is only 1mm thick, which is lightweight and will not upset the balance of the telescope. At the same time, the aluminum alloy material is and strong, ensuring stable and use for a long time.
  • USAGE: When light passes through the plates, it is diffracted in three different directions, creating three pairs of starbursts. As the telescope focus changes, the pattern will also move until the 3 tip wasps are aligned, signaling that the is in focus.
