Welcome to our store!

1. Wide Range of Use: Works with all types of telescopes, mirrors, refractors, for Dobsonians, for Mak Cas and for SCT. Just measure your telescope tube size and choose the appropriate mask size.

2. Gives the Telescope Best Focus: The mask eliminates guesswork in focusing and even overcomes seeing conditions to give your telescope the best focus quickly and easily.

3. 3 Metal Posts: The mask gently and firmly grips the telescope tube with three metal posts. These metal posts come with scratch-resistant silicone covers to protect your telescope surface. This prevents slipping while keeping the mask perfectly centered.

4. 3 Post Installation and Lightweight Design: Thanks to this 3-post attachment, the mask remains centered while fitting a wider range of telescopes. The Bahtinov focusing mask for telescopes is lightweight so it does not disturb the telescope's balance.

5. Scope of Application: The outer diameter of the bahtinov focusing mask supports the objective lens of the telescope in the range of 100-140mm (there is an error of 1-2mm in manual measurement).
