ZenithStar 73 Refractor is awesome

The Z73 has not disappointed and the team at OPT is knowledgeable, patient, and genuinely cares about the voice of the customer. You may get a slightly better price on line, but you will not get this level of service anywhere! I recommend the scope and OPT to anyone interested in obtaining a serious entry into AP.
