Farpoint Bahtinov Masks Are one of the best tools for focusing your telescope available to astrophotographers. In 2005 Pavel Bahtinov, a Russian amateur telescope maker and astronomer, detailed a new way to easily focus your DSLR, CMOS or CCD camera for astrophotography. The Bahtinov mask is placed in front of the telesocpe for the duration of focusing and then removed for the main exposure. With this great tool it is possible to get perfect focus in less than 90 seconds.
How it Works
Although the process sounds complex when written, it is actually very easy and very intuiative to use. You will be delighted with the results.
