    To focus the finderscope simply unscrew the lock-ring, rotate the objective, then re-close the lock-ring.

Bracket of the 8x50 finder:
    The metal bracket is very stable. It allows a very comfortable adjustment with 2 screws. Easy to setup and easy to use. The mounting bracket fits into standard finder shoes from Vixen, Skywatcher, Celestron etc. Additional finder shoes are available separately.
