Thanks David - I have tried this, but the shims would need a negative thickness! I've certainly improved things by going down to a few thou and it is nowhere near as bad as when I bought it from the dealer in Melbourne. The difference between the two scopes is fairly significant - the good one can split Antares, the companion sits right in the space between the first Airy ring and the centre peak.
cheers,
Andrew.
