Telescoping Telescopic
Viewing the light of stars through a telescope as opposed to the naked eye?
Say I wanted to look at a star that was 200 million light years away with my naked eye. The light I’m seeing is from 200 million years ago. Now, if I look at that same star with the Hubble telescope, am I seeing the same light that I saw with my naked eye, or does the telescopic vision capture light from much earlier?
Lots of good information. Thanks.
You are wrestling with what I have found to be a common misconception. A telescope has no way of “reaching out” to grasp photons that are proceeding toward Earth. The scope sees the same light that you see with your eye, it just:
1. Collects more photons because it is bigger than your eye (so it can see dimmer objects).
2. Focuses all those photons at your eye so that you can see a sharp image.
3. Magnifies the image.
Therefore, the time lag that is occurring on the way to your eye is that same one that occurs on the way to the telescope. The light still travels the same distance, it is what you do with that light once it gets here that makes the difference between seeing Hubble photos and seeing a typical night sky.

::: What can you do with a telescope? :::
Planets – Jupiter, Mars, Saturn, and some of the other planets in our solar system can be viewed in detail. Saturn shows us her ring, which Galileo did, I believe that Saturn had ears for many years! Also can see the moons of Saturn and Jupiter.
Luna – The Moon offers many opportunities to see, so close to us, the craters of the moon can be seen in great detail.
Distant objects – the first space telescope, especially a good telescope can show views of Nebula in the constellation of Orion, and several other galaxies in parts of heaven.
His first space telescope can see a lot more space objects to the set, however, this will help realize the enormous advantages of having a first space telescope of its own. Please note that most department stores, toy store telescopes can not reveal planet any detail, although it may say on the packaging of Nice.
::: How to buy a telescope? :::
A first space telescope is not one to overlook, a telescope, after all, is a scientific instrument. The best place to buy your first space telescope is either a dedicated telescope / astronomy or the shop line of a dedicated telescope / astronomy retailer.
Too often, people to meet the desire to see objects in the sky, go out and buy any telescope they can find. I can not complain as this is how I got my first space telescope. Soon after, I realized that this is not the best way to go. My first space telescope bought at a department store was soon relegated and never used again. The poor of the telescope mount spun easy, but it was useless to keep stable telescope to see objects in space.
Most $ 150 + planet telescope can be a great first space telescope, especially if they have been purchased telescope dedicated sellers. Another benefit of going to a store that specializes in telescopes, is that you can say about their hopes and goals of a telescope, it to help them find a telescope for your needs, rather than just getting what is available%% TF.
::: Tips for buying your first telescope:::
After years of looking at the stars, I have a few tips for buying a telescope. You need to know where things are in heaven, so make sure you have a star atlas. Another tip I can offer is to get the best telescope you can afford, because these telescopes planet of good quality will be one that will last years.
A telescope can truly be an incredible tool to use. A telescope astronomy leads to life, and makes the points in the sky be significant. Imagine seeing galaxies, planets, nebulae and throughout the universe. All this is possible with telescopes at the planet that are available to you.
