Maybe my scope has magic powers
my C11 on the other hand, is a dew magnet
I'd recommend a dew shield at least as it also serves to prevent stray light affecting the view. If you're observing from home, you can always melt the dew off your scope with a hair dryer (with care of course)...another tip I learned, admittedly easier to do on an equatorial mount, is to rotate the scope so it is facing the ground for a few minutes.
Another strategy to consider if you don't get a heater strap immediately is to avoid pointing toward the zenith for too long, especially right after sun down when I find the steep temperature drop exacerbates the situation.
Maybe we should call this "dew management"
