I have been monitoring this thread for a while. After some thinking I have come to the conclusion that the Questar 3.5 is perhaps the best telescope for Community Outreach Astronomy in a class room setting. It's the perfect size and built (almost) like a tank, but I'm pretty sure that everyone like me who shares the night sky with others asks people not to touch the equipment.
Also, the Questar is a beautiful telescope, with its brushed aluminum and vibrant colours it is a scope that's hard to ignore. You are doing a valueable service by showing school kids about telescopes. Some may end up becoming amateurs themselves plus it gets them asking questions like: why can't we see the stars in the city like we can when we go camping or are visiting a National Park?
Who knows what will grow when we plant a seed.
