Guidelines for Selecting a Telescope — There comes a time in every stargazer’s life when they decide to invest in their first telescope. This can be a confusing and exhausting experience for many who have never looked at telescopes before and don’t know much about telescopes or what to look for. If you consider yourself one of these people hopefully the advice below will be useful.
Just about the most prevalent oversight consumers make with regard to finding their own first telescope is definitely paying attention solely to the magnification of the telescope. Actually in reality the magnification is not nearly as vital as the aperture. Aperture, in terms of telescopes, is the size of the objective lens that gathers light from celestial objects, located at the far end of the telescope.
The longer the aperture width, the brighter the celestial targets appear in the viewfinder, and therefore the greater quantity of dim objects that can be viewed. A general misconception is the notion that the numerous deep space galaxies that can’t be viewed normally, can’t be viewed by way of the naked eye because they appear too tiny, when usually it is really because they are simply not apparently bright enough.
For that reason the most important item you should spend your hard earned money towards in terms of optical capability is aperture size, not magnification.
The aperture additionally establishes the amount of useful magnification a telescope has. It’s not a good idea to try and buy magnifications in excess of 50 times the actual aperture in inches (or 2 times the aperture in millimeters). Meaning that in the case of a telescope that comes with a 8″ aperture, do not anticipate to have the ability to see clearly with magnifications past 400x. Any further than that, the telescope’s aperture size won’t be capable of supporting the increased magnifications which will make the view very fuzzy and blurry.
So far as the available magnifications of telescopes go, they normally are determined by the eyepiece chosen. Telescopes will normally come with no less than one eyepiece, and extra can be purchased. Some inexpensive telescopes possess fixed eyepiece with a set magnification, but most can be adapted to have as large of a magnification as is desired (remember the practical magnification is bound by the aperture).
Make sure to take into account quality, size, and price into your considerations. Usually the higher the price the better quality the optics. Be sure though that any extra money you spend on quality optics will be noticed. It would be a waste to spend hundreds of extra dollars on improved contrasts if your eye isn’t even experienced enough to notice the difference.
Also another thing worth thinking about is size. Many people fall into the trap of buying large telescopes, but end up never using them because they are just too much of a hassle to move and set up each time. Its worth spending extra money on a more compact telescope if it means you will actually use it.
So you’ve invested in that splendid shining cutting edge telescope that has Goto technology, but it really just will not show the thing you’re attempting to observe. You will not be the only person to be frustrated by this but you may increase the preciseness of your telescope by a handful of uncomplicated tactics.
In order for a Goto telescope to become more accurate there are a variety of issues that ought to know. With a little luck, by following most of these straight-forward points you can increase the correctness of the telescope and be enjoying the evening sky together with its wonders right away.
Do you find it difficult to accurately place a star in the middle of the area of vision when you’re setting your Goto? It’s not easy to place a star in the centre of a big area of vision. You’ll be able to increase your exactness by way of making the star bigger. So long as you defocus the star it will differ from a point of light into a circle of light. This specific defocused circle of starlight is easier to keep in the centre of the field of vision.
After you have it centred change to your greater strength eyepiece then perform the same to really have exact alignment. Always refocus right before substituting lenses though or else you could lose the place your former star was.
Before you even switch your telescope on unquestionably the inaccuracy can start. Your telescope needs to be level to the floor to help make optimum utilization of your Goto tools. A few telescopes feature a built in spirit level, but if you don’t have this it is easy to implement a spirit level. Quite a few touch screen phones incorporate spirit level apps that can be obtained for nothing from mobile application web stores.
Spend some time getting this exact. it really is the single and most typical trigger for inaccuracy. Don’t neglect to make sure that your telescope is put upon soft land in order to reduce shaking when you are viewing. Push the telescope tripod in to the ground and make sure the land won’t be way too soft or maybe the telescope can sink after a while and then the telescope will have to often be levelled.
Find specifically where you are earth. It is readily accessible on the iPhone’s compass if the telescope doesn’t contain Tracking built-in. Install the app on the iPhone and the software demonstrates your current longitude along with latitude at the base of the touch screen.
Otherwise, you can discover your current coordinates totally free using online websites by merely placing in your own address or even postcode. That is it. We hope as soon as you adopt these measures some of those depressing Goto occasions will be a subject of the past.
Ever since time immemorial man has had a fascination with the stars. The most famous person of astronomy, and greatest stargazer of them all was Galileo. Galileo of Italy lived from 1564 – 1642 making him 78 years old at the time of his death.
This most famous astronomer not only had made major improvements to the telescope and consequential astronomical observations, but was also known as the Father of Science and Physics.
There’s An Explorer in All of Us
Perhaps there’s a little bit of Galileo in all of us. I know that ever since I was a kid that, and even still today, when I look up into the stars there is amazement in my mind. And what is the most famous thing we look for when we look into the heavens?
Yes, the Big Dipper and the Little Dipper. Then when I was a young boy I got my first telescope. My amazement became even greater at that point. Because now I was almost able to reach out and touch the stars. It was awesome.
Telescopes and Astronomy have come a long way since the time of Galileo. Even for the home stargazer like us. Another thing I always thought would be a cool thing to experience would be to go to an observatory.
And have an opportunity to look out into the Universe and see the Northern Lights up close for example. With the power of an Observatory telescope this is absolutely possible today. How awesome do you think that would be. Wow!
Bless The Older Way
Today for the casual or home telescope enthusiast, as well as those entrenched in Science and Physics, telescopes and astronomy have been coupled with the power of the Global Positioning System or GPS. In this article I will tell you how that makes astronomy better for all of us to enjoy.
Most telescopes today are becoming more and more computerized like everything else. In themselves you can get one that has very powerful magnification. The older telescopes without GPS are much harder to work with. Let me explain.
Older telescopes that didn’t have any computerization to them, were crude in the way you had to get them fixated on a certain star or planet that you wanted to observe. Once you were able to find the certain planet, for example you wanted to see, even though the magnification of your scope was very good it was difficult to observe because of the rotation of the earth.
You would have to continually adjust for the rotation of earth to be able to stay with your object in the heavens. Making it difficult to observe. Then you also had to deal with the shaking of your hands as you move it as well.
Oh, The Power of The New Way
Enter the newer telescopes with computerization and GPS. Scopes with GPS are called Go-To telescopes. These telescopes give you lots of information about the object your viewing.
Such as the name of the object or planet, how many moons it has, the distance, .. Mucho amounts of information from one of these telescopes could make your kid ace his or her science class or astronomy project in a matter of minutes, not days or hours. Very powerful!
Now lets see how the GPS side of this helps us enjoy astronomy so much better. These go-to telescopes are just that. For example you locate the planet by the GPS that you want to observe.
Once the GPS finds the planet, you lock on to it by the GPS. These telescopes are equipped with computer mechanized motors on them. You simply lock on to the object, focus, and then enjoy.
Because the GPS works with the computer mechanism to compensate for the rotation of the earth. This means you only have to lock onto the object once. Never again for as long as you want to view it.
The telescope will constantly rotate with the rotation of the earth. Staying locked on and focused to the object. The only thing you have to do is move with it to keep you eyes looking through the viewfinder.
The Better Way Conclusion
Is that cool or what? This is how GPS and telescopes together make astronomy much better for us as enthusiasts. These telescopes can run into the thousands of dollars depending on the power you want.
