Thanks for your responses guys, not sure that I'd be confident enough to tackle such a high end scope as the Esprit 100. To be honest, the residue the condensation has left behind is quite visible but has done little to the images it produces. If I was reassured it has not or will not continue to damage the lens coatings, I will just leave it alone and live with it. I have called Sky watcher Australia and they need to see the lens to assess the condition. I can't imagine it being a cheap fix because if the coatings have been affected then cleaning won't remove the blemishes. I'm worried about using it in winter now because the temperature between outside and inside where the scope is housed are too extreme.
