Hello friends... I purchased a used WO bino. No eyepieces or barlow. Works GREAT in my cat. Works great with 2x Barlow in my refractor. But... I know there is a WO 1.25 nosepiece. Will this give me enough in travel for focus with my SW 120ED? Thanks for any advice!

What does the 2X Barlow attach to?
Do you use the 2X Barlow in the Cat?
IME a 120ED will need an OCS/Barlow to reach Focus. Maybe not as much as 2X but definitely a 1.6X OCS.
Also, did the SW 120ED replace the ES 127 and why is it not listed in your Signature!

is the 1.6x oca available separately? I would like to get one if I can.
only the 2x WO OCA is available separately AFAIK.

Siebert makes a few but they aren't cheap or as straight forward as the conventional one's.
