Focus accurately in seconds!
Bahtinov masks are a invaluable tool for all astrophotographers and even visual astronomers! They sit on the aperture of your telescope of lens and create diffraction spikes to accurately display your current focus. When the centre spike is aligned you are in perfect focus.

These masks are fitted to your telescope with variable posts and a protective silicone tubing.

Pick the mask that fits the size of scope or lens. Measure the diameter of the whole front of scope including dew shield! (See Image 2)
