What does make a big difference is the corrector used. I found the the Mk 3 MPCC very frustrating with my scope(Royce 10" f4). I changed to a type 2 Paracorr and it was instant goodness. It does slow the scope down to f4.6 but that a very good trade off for how well it performs.

That's interesting.
I wonder what my Baader RCC coma corrector is doing then?
see here:

ASA has more expensive ones here:

I wondered if they would really be better or noticeable?
If I have good seeing in Melbourne I get say 2 arc seconds at the center
of the FOV & about 2.8 at the edge of the FOV with a KAF8300 chip.
I wonder if that's all I'll ever get?
If I went to high altitude to grab 1 arc second seeing then I suppose I could really test it.
