Telescope Buying Guide

Zander asked:


I’m new at this whole amazing thing and I am quite a beginner at this telescope thing. There is this website (very reliable) where you can bid or buy stuff and this one guy is selling this 102×500 SkyWatcher f/5 telescope for only NZ$30. Is this a good telescope to begin with?

Thanks

Yahoo! News reports: “The Hubble Space Telescope has captured the earliest image yet of the universe — just 600 million years after the Big Bang, when the universe was just a toddler.”

How is this possible?

I want to know how they came about or why they wanted to invent the telescope. I need this information for History Day.

Read an article on line about this and I am not sure I understand how it works; the article actually referred to the telescopes ability to photograph “back in time” and it lost me completely. I mean, does the telescope view what’s out there now and calculate backwards to come to a conclusion as to what the universe was like then? Anyone who can shed light, please do.

It seems like we should be able to see the moon lander etc from the space telescope.

Evan R asked:


Please have a source, and if possible, the name of the telescope.

I don’t quite understand how they determine that the galaxies in some ultra-deep-field pictures are billions of years old… How do they determine that? How do they know that they are looking into the past of the universe? If they determine that the distance of the galaxies is, for example, 13 billion light years, that means that the light the telescope is able to capture has been traveling for 13 billion years, right? But then how is it that they determine that those are the early galaxies in the universe and that those galaxies were formed soon after the Big Bang? Can someone please explain with simple and easy-to-understand terms? Maybe some examples? Thanks!

I recently bought a telescope and tried to see jupiter and mars; however, they just look like really small bright dots even at 180x magnification. Is this how they supposed to look?
