Would I be better with a 2" or 1.25"?
Any thoughts on the this on http://www.myastroshop.com.au/guides...ar-reducer.htm or there's one at andrews on the Guan Sheng Acc. page.
Any thoughts/suggetions.

Hi John,
I only just came across this thread. I recently purchased the "latest" William Optics flattener/reducer III, which is specifically designed for f7 to f7.5 scopes. I am "testing" it at the moment with my ED120, and so far the results are fairly promising......

I have also the Hotech SCA Flattener, and this works superbly with the ED120 aswell. However, my main reason for trying the WO III is to try and "quicken" the iamging system from f7.5 to f6.
Hope this helps.
Cheers,
Daniel
