Achieve perfect focus with this custom 3D printed Bahtinov mask designed specifically for Celestron NexStar telescopes.

If you would like a different size, please let me know and I can add what you need.

Items will be shipped in black by default; however, if you prefer another color, simply drop me a message, and I'll be happy to accommodate your preference.

The Bahtinov mask consists of three separate grids strategically positioned to create three angled diffraction spikes at the focal plane, aligning with each bright image element. As you adjust the telescope's focus, the central spike moves across the star from one side to the other, allowing for precise focusing.
