Lumicon 50mm Finder - 80s Vintage Livermore, Ca. no google and dynamic sonic profile withThis is an 80' Vintage Lumicon 50mm finder, I am the original owner and I bought it prior to the '84 central annular eclipse. Sharp optics and easy to use with a wide field of view. Includes a 25mm Kellner eyepiece with double cross hairs, and a 90diagonal. Optics are excellent, and the barrel has a few indications of scratches and clamp marks consistant with 40+ years of careful use. Lumicon 50mm Finder Objective Lens: Fully Multi Coated 50mm
