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.
