I can not imagine observing under poor to average conditions. I would much rather have a few great nights per month than a dozen ho-hum nights. There's plenty of times I've been out with poor atmospheric conditions only to find myself packing up a half hour later. Why bother? After all,I bought a telescope to "see" things. When conditions are bad, and I can't see what I want to see,why waste my time? I want quality views and because of that I have to pay the price. It's worth it as the satisfaction lasts much longer than with cheap views.
