I very much doubt that. As far as I know I'm the second owner and the scope has never been mistreated.
But this is the Moon, at not far off the widest FOV the scope was designed for, and my focus was only so-so. The Moon was also very low in the sky. And it's a 24MPix DX sensor.
Visually I never had issues with CA. The scope could handle planets no probs at up to 300x (though in practice 240x or less is always sharper). It's just that for this particular photo, for whatever reason, using only the green channel made sense.
I'm neither alert nor alarmed.
