1.25" - 2" thread adaptor???

[Andrew*]

My deep sky filters are all 2" as I usually screw it on the 2" adaptor when using 1.25" eyepieces.

However, my binoviewers have an extremely long barrel (5" or so), so I can't screw filters onto the adaptor.

A solution could be to use a step-up ring on the end of the binoviewers to convert a 1.25" thread into a 2" one.

Does such an adaptor exist?

Any alternative ideas to save me buying 1.25" filters?

Cheers

Andrew

You would have to assemble the lot with the 2" > 1 1/4" captive on the barrel?

indeed. Not a bother if it saves me doubling up my filters...
