Article: How to use a Bahtinov Focus Mask with a DSLR camera

Bahtinov focus masks are easy to use. Before attaching the mask, aim your lens or telescope at a bright star and manually adjust the focus of your lens or telescope until it looks close to focus. Then, gently attach the bahtinov mask. The mask will diffract the light into three spikes. Adjust focus until the middle spike is centered, then carefully remove the mask to begin viewing.
