I'm picking up an older (> 15 years) Omcon EX 118 4" refractor later today. Omcon was a Canadian brand, from the same parent that makes Antares equipment. They typically build the scopes in Canada with optics sourced from Asia. Earlier versions used Vixen objectives, and newer ones used Synta,
Is there a simple way to identify visually whether the objective is a Vixen - any obvious distinguishing features? It doesn't look like there are any labels on the scope that identify the optics supplier.
Either way, I'll be happy but I would like to know.
