Baader MPCC multi purpose coma corrector

I noticed there was a question on the Tele-Vue Para-Corr. A person might want to consider the much less expensive Baader MPCC that is configured for visual or photo use in f/4 to f/6 reflectors by making use of various T-2 system accessories. The T-2 mount allows use with all but the largest 2" EP's that have field stops bigger than T-2 size.

A simple $20 T-ring adapter allows use with a 35mm SLR camera. You screw it onto a T-2 Click-Lock for use with 1.25" EP's. It screws directly onto 2" EP's. VArious T-2 extenders give the right insertion optical length for 1.25" EP's. Usually a 15mm extender between MPCC And Click-Lock.

When I read the information on the Baader Paracorr it seemed there was more to it for visual use than just the corrector. Plus, the sites I visited left me unknowing just how it could be used visually with 1.25" EPs.
Most talked to photographic use or how to attach it to a 2" EP. Can you explain or provide a site that does a better job of describing visual use with 1.25" EPs.
