That's a pity - looks like more money to spend and they aren't cheap.
I had a Hirsch f/6.3 reducer that wasn't too good so I bought a Celestron brand hoping it would be better.
It is better - but as with the Hirsch the collimation drops off rapidly from the centre of view. I suspected the field can't be too flat if the collimation isn't good over the whole field. My first image wasn't too bad but my next too were useless.
I'll try again. Otherwise, as difficult as it is, I'll go back to imaging at f/10.\ until I decide to buy another reducer.
Tony.
