Re: Upgrade 10" to 12"-is this worth?

Regarding the discussion of cool down... Viewing through a scope that is cooling down is like observing in less than perfect seeing... there is no reason to wait if the skies are dark and there are no clouds. Pick your targets based on usable magnifications. When the scope is cooled down and thermally stable, push the limits of the seeing. Until, then, just have fun.
