Building on the design by Russian amateur telescope maker and astronomer Pavel Bahtinov, the Farpoint Tri-Bahtinov Focus and Collimation Mask can be used to quickly and easily confirm your OTA s collimation and then focus your telescope for all types of astrophotography with DSLRs or imaging systems. The " Tri" in the name refers to the advanced design of the maskit is essentially three masks in one unit, rotated over 120-degrees, that gives you three lines and three crosses to check the collimation along three axes at the same time.
