Make your focusing for astrophotography an easy and magic task .

About Bahtinov mask?
The?Bahtinov mask?is a device used to focus small astronomical telescopes accurately. It was invented by Russian amateur astrophotographer?Pavel Bahtinov?in 2008. Accurate focusing of?telescopes?and?astrographs?is particularly of concern to those involved in?astrophotography. The telescope is pointed at a bright?star, and a mask is placed in front of the telescope's?objective?(e.g. primary mirror).

How does it work?
Set up your telescope and imaging equipment as normal. Then simply locate a bright star (maybe Spica?) with your telescope, attach the Bahtinov mask to your telescope and watch the diffraction spike pattern around the star as you adjust the focus. When the middle diffraction spike is centered in the outer spikes, you're in focus. Very little focusing travel is required to move the inner diffraction spike, which means the focus is extremely accurate.
