Yes, that's good news to have it back and that you're happy with it!
Please, tell us more about what to look for. I'm not sure what I should be looking at in the photo.
Hmmm you ention the sweet spot and focus just snapping in... I don't think mine is like that, focus is not what I would call definite, and at times I do struggle to get surface detail, especially, say, orange peel. I hope mine doesn't have a problem as well...
I'm keen to understand what problem your scope had, so I can be sure if mine's OK or not!
Thanks,
Al.
