Quote: While the double pass was a novel idea. I am glad to see the ability and versitility of the double stack.
Agreed. It does raise one question: what size will the external filter be? There doesn't appear to be a 60mm external filter available.
AFAIK, the LS 50mm Ha external filter can be doublestacked on the 60mm by simply threading it onto the dewshield part.
Furthermore, I was told by Marcus Ludes that factory matching will not be necessary for those who want to double stack thier 60mm single pass Ha scope, with that filter, at a later time.
Correction Update: Apparently there will be a 60mm externally doublestacked at the factory.
