1. 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.
2. 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 durable and strong, ensuring stable and reliable use for a long time.
3. 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 starburst pattern will also move until the 3 tip wasps are aligned, signaling that the star point is in focus.Specification:
