A word of caution, Grant. I have that model and it is superb, but with one limitation. The slit is a bit narrow. They widened it in later models.
Consequence is that when the scope is pointing obliquely across the slit, it doesn’t take very long before you need to shift the dome round a bit. The wider the scope, the shorter the time. Can be a pain if you are doing a long time series run. I’ve long thought my C11 is at the practical limit. I wouldn’t like to use a 12-inch.
