Bahtinov Focus & Collimation Masks
Use a Bahtinov mask to dial in telescope focus on a bright star, or choose a Tri-Bahtinov mask to evaluate focus and collimation. The rotating isolation mask helps inspect one Tri-Bahtinov sector at a time.
Each mask is made to order for the telescope model you select.
