Hi Everyone, need a little help choosing the right flattener/reducer for the William Optics Zenithstar73. I am after one that does both jobs so that rules out the dedicated Flat73 which is just a flattener! So I was wondering if I could get away with the Flat6 0.8 reducer which does say it works on scopes 70 - 80mm f/6 but doesn't list the ZS73 in the models list or do I need to spend the extra and get the Flat6A11? Can anyone shed some light on this have email 365 where I have seen the Flat6 but had no reply. Thanks in advance.
