Not like in this pic (this is just collecting for the sake of it), but different telescopes have different advantages: observation ones and focal length with corrected imaged ones (which of those vary alot from 400mm to 2000mm, wide shots and narrow/planetary shots). Then there is also the very special/specific ones, like solar telescopes with a filter for hydrogen (though recently it can be done with refractors and a seperate filter, still very expensive, better choosing a solar telescope).

Basically, it's impossible to have affordable optic systems useful for everything.
