Is there a website that shows equivalent views through different telescopes? I'm trying to buy a beginners telescope. I have a Celestron TravelScope, but would like something better. When I look at other models, many users have posted images from their viewfinders. Is there a site that collates all of these, to give an idea of what I can expect from a given scope (e.g. is Mars just a red dot, can I make out Saturn's rings, what's the detail on the moon like, etc)?
Deep sky watch has an article that covers this

It includes sample image of what can be seen in, for example, a medium telescope (150mm objective) with 180x magnification
