What's a good telescope to buy? Looking for something in the $1000-2000 range, purely for amateur recreational purposes. I know next to nothing about brands and models and such.

Just curious /sci/
Lets say we build the largest possible telescope array in space, perhaps at the lagrange point between the earth and moon.
What would be the best possible resolution we could get from this telescope? How far away could we make out meter sized objects on another planet or astroid? What are the limitations?

You have ten minutes of time with the Hubble telescope. All data will be recorded. You may point it at anything. What do you point it at?

I used this for the longest time, then the scientists wanted it back after they found out I was perving on their wives and daughters.

Artificial stuff 3/4

So, what kind of telescope are you?

If the planet was 20,000km in diameter (and we wanted to resolve details 10,000km across) at 10 light years away, that's about 0.0000000436 arcseconds across..

To have a telescope that would directly "see" that, we'd need a telescope with an aperture (mirror or lens size) of over 2500km!

Might be a while before we can make one

How close are we to directly imaging an earth sized extra-solar planet with the same resolution as we would see any other planet in our solar system? Is this possible with current technology just by making a really really big telescope (thus our only limitations would be the practicality of building something so big) , or are there other issues that would need to be addressed?
