My trusty old MPCC worked. Out of the box. Almost. I must be doing something wrong. You know. Cheap-Chinese-rubbish-not-worth-the-paper-it's-written-on and all that. But wait. I think Baader are German. Ah, but made in China of course.
Must try the Cheap Chinese SWCC. Not only a cc but a 0.9 reducer: 208mm f3.5? I wonder.
Time to test the cc. Star fields are tough on all ccs...
