Cats Eye nebula Photo Mugs
 |
DescriptionCats Eye nebula. Hubble Space Telescope image of the Cats Eye nebula (NGC 6543). This is a planetary nebula, shells of gas cast off by a dying star, whose light illuminates them. The star is seen at the centre of the nebula. The name is misleading, as planetary nebulae have nothing to do with planets. The structure of the gas shells is extremely intricate, and reveals much about the star and its slow death. The central regions show dense Features

Astronomical Telescope – Amazing Link to the Stars
For most people, telescope is easily associated to the stars, the planets, asteroids, the moon and its craters and the heavens in general. In my case, when I see a even just the simple reflecting telescope (or maybe a telescope observatory or planetarium) I can only quickly think about astronomy and how this optical wonder of a gadget has been a great help in the development and advancement of this amazing science.
What actually are telescopes? The most popular ones are the refracting telescope as well as the reflecting telescope. Scopes are the best device to use if you want to view far away objects. This is made possible via magnification.
How do Refracting and Reflecting Telescope Gadgets Work?
The principal mechanism in which a telescope works is quite simple. A scope has a double lens; such lenses are where you look through to clearly see distant objects. The first of the lenses receives the light coming from the object and then throws it onto a focal point. The second lens then receives the light from the point, which then is spread out to the retina of the eye and in effect making the distant object viewable.
The first lens which receives light from the distant object is the primary mirror or objective lens. While the second lens that receives light coming from the focal point is the eyepiece.
The efficiency of the reflecting telescope is determined via its capacity to collect light and enlarge the image of the object. More light can be collected as the telescope becomes larger. Image enlargement on the other hand depends on the quality and type of lens combination.
Indeed, you only need to utilize your reflecting telescope when it comes to efficiently scanning and observing the skies and outer space and at the time being at awe with all the amazing stars and heavenly bodies that they offer.

What is a good price to pay for a first telescope at age 13?
I just got into astronomy and I really want a telescope. I get $8.60 pocket money per week (NZ). What is a good price to pay? I only want something that will magnify the stars, no fancy stuff.
If you don't have a lot of money to burn, you might want to start out with a pair of binoculars, like 7x50 or 10x50. They'll show you more stars than you could ever see by eye, as well as few deep-sky objects, like the brighter galaxies and star clusters. They're light, low-maintenance, and can take in huge swaths of the night sky.
One of the reasons I recommend binocs is that good telescopes aren't cheap. Personally, I wouldn't recommend paying less than $200 for one, though a decent scope can be had for that price. Whatever telescope you buy, make sure it's from a reputable manufacturer, like Orion, Meade, or Celestron. Avoid any and every telescope by Tasco, Bushnell, or Jason.
Speaking of Orion, they have a selection of good telescopes (and binoculars, for that matter) for under $200...
Best of luck!
