Telescope Buying Guide

Andrew asked:


If you had access to the Hubble Space Telescope, which has an angular resolution of 0.1 arcsec. What is the size (in kilometers) of the smallest feature you could have seen on the Martian surface during the 2005 opposition, when Mars was 0.464 AU from Earth?

newyorkchess2005 asked:


that is really strong and bring the telescope with you, as your looking back on Earth the way it was ages ago, can you see the people on it thousands of years ago and the other events happening?

Would you see Jesus and wars that were happening back then?

Is it possible?

What is the telescope/probe/satellite that is flying out of the galaxy? I know that the Hubble only goes around earth, but i believe there is one that is flying outward.

adil k asked:


You probably know the hubble telescope which is named after a famous scientist Edwin Hubble. I was wondering where would it go afters its mission and on wikipedia i read that its going to be deorbited probably from 2016 to 2021. But can you tell me that will it return to the earth or stay up in space like an interstellar probe?

If I bought a telescope from walmart would it be good enough to give me a good view of astronauts doing a space walk? could I read the writings on the space shuttle with it?
Even from Earth it is possible to see some details of the Station, such as the solar panels and even the Station’s robotic arm, but you will need some more powerful equipment.

Mazhar H asked:


Can I see pluto from a telescope like we see monn from earth? Now you will ask which type of telescope. So, which is good means above fine which is mostly affordable, pricing between $250 USD to $300 USD. I do not have any information about telescopes, I have never seen them in my life. But I am interesting in buying one and want to know that how far can I explore? Can I see stars from closer? Can I see planets? etc…

Connor R asked:


If we sent a space ship with a telescope on it a few thousand light years away from earth and looked back on earth would we see earth a few thousand years ago?
