The Bahtinov Mask is a focusing tool which enables extremely precise adjustment of your telescopes focus - particularly useful if trying to focus a dedicated astro-camera (but also works fine for DSLR)

Attaching the Bahtinov Mask to your telescope or lens is very simple. Each mask is supplied with 3 screws. Remove the plastic from the screws, put them through the designated holes and then pull the plastic covers back over the screws. Now you can attach the focusing mask to the front of your telescope or lens and start focusing.

Some useful tips:

Using a Bahtinov Mask for focusing works really well for Deep Sky astrophotography. Correctors and Barlow Lenses are also fine to use too.
Ideally you want to use a star with medium brightness for focusing. It should neither be too dark nor too bright. The lines of the Bahtinov interference pattern will need to be clearly visible.
The chosen star shouldn´t be positioned in the center of your live view, because most telescopes or lenses, although corrected, do not produce a flat field of view. We recommend positioning your selected star to the outer part of your field of view, That way, you will achieve a better overall sharpness across your whole field of view.
