While I acknowledge that the design of the Baader MPCCMKIIIs barrel is not the best in terms of how it interacts with a compression fitting and this likely works fine with a SWCC, I feel that as the MPCCMKIII is probably the most popular Coma Corrector used on Sky-watcher Newtonians the opportunity to account for the MPCCMKIII in the design of this item was missed. In the end I went back to using the original.
Upgrade for my Orion 10 DOB focuser

Just wanted to stop any marking of my 2" EP etc. Don't know why manufacturers don't fit compression rings to focusers as standard.
Screw the old one off and on with the new. Not up to Baader quality but not Baader prices either.
Does the job well. I like the larger thumbscrews with good length so you can tighten without having to fiddle about at the base of the EP .
