I used a hairdryer too, a long long time ago when I started planetary imaging with a 180 Maksutov. Not a good idea to heat your optics when you try to image at the theoretical limit of your scope, but if you get dewed up there is no other option.
Your link is a good place to start for beginners, however, I would not recommend planetary imaging with scopes below 250mm aperture.
