Tectron autocollimator is in excellent condition.
The booklet "Perspectives on Collimation-Principles and procedures" by Vic Menard and Tippy D'Auria is in good condition. You need the booklet to explain how to use the autocollimator effecively.
It's $30.00 shipped in the lower 48. Anywhere else and we need to talk. Either a postal money order or cashiers check will do. Thanks.
