bino mate for 32mm plossl

[doug mc]

I have a 32mm Orion Sirius plossl, was wondering if I can't get one locally, would a GSO 32mm super plossl be ok to bino it with?

the plossl do not appear to be the same make -diff weight & slightly diff field stop -it's possible the magnification are ever so slightly diff -eg one may be 31.7mm & the other 32.4 -it will depend how accomodating your brain is when seen thru your eyes -they may be close enough but may not
try & borrow one first

Thanks Daniel, I might just get 2 GSO 32mm plossls and sell the Orion. Looking through the 32mm in the bino at M42 the other night I certainly noticed the extra real field of view. The outer field was darkened as expected but the gain in real field and brightness by lowering the power in my C8 I think is worth it.
