If you are going with a schmidt-cassegrain, you will definitely need a dew shield, as they are notorious for dewing-up their corrector plates. You may even need to heat your dew shield, as I always had to do back when I owned one.
Have you considered a nice short focus apo refractor?-great for photography, superb images and usually have an effective dew shield built in. And you can put it on an alt-az mount if you so desire.
I don't understand why you have problems with a gem though.
Good luck with whatever you decide.
