I'd certainly disagree with this idea. A smaller telescope with excellent figure will show fainter stars than a larger one with a mediochre figure - so less weight to carry around and less thermal mass. I've seen this myself with an excellent 20" against a 36". When it comes to non - stellar sources things probably get more complicated.
