Hi Dunk,

Yes, the two cameras I'm considering are the ZWO ASI290MM and ASI178MM. I realise the fact that they are mono brings extra expense, but it's where I want to end up anyway so I might as well save for a while longer and do this properly.

Am I correct to think that, other considerations aside, a pixel size of around 3um is optimal for this scope (without barlow or reducer) when considering a camera for lunar/planetary?
