Telescopes gather light and make for the most spectacular viewing experiences. The thrill of viewing distant galaxies, bright star clusters, unique nebulae, solar system planets and lunar features is most indescribable.

1. ane

   Consider the type of telescope. Unlike telescopes are better for dissimilar types of viewing. At that place are actually on 3 bones telescope types: refractor, reflector and catadioptric. Which one you cull will be based on what y'all desire to observe, where you lot are, so on.^[1]

   • The refractor basically has a long thin tube with an objective lens at the forepart that collects and focuses the lite. This ane is better for viewing the Moon and planets, usually giving a nice, crisp image. Information technology travels well and doesn't need much maintenance. Unfortunately, it is very difficult to see faint objects like galaxies and nebulae.
   • The reflector employs a big concave mirror rather than a lens for the purposes of accumulating and focusing calorie-free. This is i of the amend beginner telescopes and information technology normally has pretty skilful visibility, although h2o has a tendency to condense on the optics of the telescope which tin can be irritating. As well, you can't view terrestrial objects with this telescope, because they will appear upside-downwardly.
   • The catadioptric is a chemical compound telescope, combining both lenses and mirrors. They are proficient photographic telescopes and they are a lot easier to carry than the reflector. This ane tends to be more versatile, just they do tend to be more expensive than the other types.

2. 2

   Consider where y'all alive. You'll need different power levels considering where you are. If you have an expanse where the lite pollution is improve or worse. If y'all are in an expanse where information technology rains more, etc.^[two]

   • If you want to bird sentinel (for example) with your telescope, you'll be improve off not choosing the reflector telescope because it won't show you lot terrestrial objects.
   • If you're in a place where information technology dews often and you're planning on using your telescope at night, you'll need to consider whether choosing a refractor or catadioptric telescope might be your all-time choice.

3. 3

   Consider what you lot want to wait at. Objects like the planets, the Moon, and closer stars need a high power, good contrast and sharp resolution in a telescope. So if this is what you want to look at, your best bet is to go with a refractor or a reflector. If you're looking at faint objects such as galaxies and nebulae, y'all'll need a bigger aperture and choose a big reflector telescope.

4. iv

   Consider the power capabilities of your telescope. People generally have the mistaken impression that more power automatically means higher resolution and better viewing, but this is not actually true. High power simply dilutes the brightness of the paradigm and amplifies any blurriness.^[3]

   • For any telescope the maximum corporeality of magnification equals l-power per inch of aperture. So say you have a 6-inch reflector. 300-power is every bit loftier as you should go (for a 3-inch reflector information technology would be about 150-power).
   • Even if you're using a Barlow lens, magnifying it too far will merely result in a blurred epitome. The telescope'south image tin can only be diddled up to a certain point.

1. 1

   Learn the finderscope. This is typically attached the side of the telescope. It displays more of the sky than the telescopic itself. For case, a 50 ability telescope covers an surface area about as modest every bit the fingernail on your little finger, whereas an 8x finderscope covers an area nearly the size of a golf ball.

2. 2

   Learn the mount. Telescopes typically come up in two types: equatorial or altazimuth. You'll need to know which kind of telescope you have so you tin can learn how to operate your telescope.^[four]

   • Altazimuth mountain operates my going upwards and down and side to side, making information technology easier for beginners to operate. It is more than simple than the equatorial telescope.
   • Equatorial mount swings across the celestial Northward to Due south and Due east to Westward. The polar axis (which is the rotating part closer to the telescope's base) needs to be aligned to Polaris, the Due north Star. It will then follow the motion of the sky around this betoken, moving from eastward to the w (every bit the stars move).
   • It takes more time to get accepted to the equatorial mount each fourth dimension you want to expect at a different star or planet y'all accept to unlock the axis and accept aim at the heavenly body using the finderscope and lock it one time you have the general location. From there you'll apply the boring move cable controls or panhandle controls to make the smaller movements. The equatorial mount is generally considered to be more helpful.

3. 3

   Larn the tripod. You'll need to make sure that the three legs of your telescope are properly balanced otherwise the telescope tin can fall over and get damaged. When you lot're scouting out locations, e'er await for areas that have a flat, level expanse for your telescope.

1. 1

   Learn the sky. Before you lot offset tromping around in the dark with your expensive telescope, you'll need to figure out what you're looking for. Maybe you want to accept a gander at the moon, or want to bank check out the planets. Possibly yous're interested in a meteor shower. You'll need to detect out timing, place, atmospheric condition, etc.^[five]

   • If you're trying to observe the stars, for case, going out on a moon-lit night won't get you very far.
   • Look at books on stars and constellations. These will tell you when the all-time viewing times are and when the planets are easiest to be seen.
   • Examine sky charts then that when you are out in the nighttime you know where to point your telescope.
   • Train your center. To do so, brand sketches of the moon and the planets. You don't have to be a great creative person to capture them every bit accurately equally possible. This will assist you to expect more closely at the sky and observe details.

2. two

   Choose your spot. Yous'll need to choose your spot carefully, one time you've decided what you're looking for and where it will be. Information technology volition need to be accessible at night and have a place with solid level footing for your telescope's tripod.^[6]

   • You lot'll demand to consider light pollution. For example, if you're in a big urban center, going upwardly on a loftier roof (As long as it is safe) can go you abroad from the worst of the calorie-free pollution and permit yous to run into more conspicuously.
   • Effort to avoid decks and blacktop driveways and concrete. Footsteps on a deck can cause vibrations in the epitome. Blacktops driveways and concrete tin can create thermal issues for your telescope.

3. 3

   Practice. You'll need to practice setting up your telescope and pointing to the correct part of the sky before you start fiddling effectually at night. Otherwise information technology is very easy to lose bits of your telescope and forget how to do something.

   • For do set your telescope and, using the everyman power eyepiece, indicate the main scope at something about 100 anxiety (30.5 grand) away like a tree (not the sun!). Center the object in your crosshairs and make certain it's clear. Switch to a college powered eyepiece and try again.

4. 4

   Be comfortable. Make sure that when y'all're having your big night out with the stars that y'all take dressed appropriately. If it is going to exist cold, make sure you take the correct clothes on and bring along a canister of something warm.

Add New Question

• Question

  Do you continue both optics open, or practice you shut the eye that is not looking through the telescope?

  

  Yous keep both eyes open because if you close one eye, your open eye vibrates slightly. This leads to the image being blurrier.

• Question

  Is the curt lens the lowest power lens?

  

  No. The shortest one is the most powerful. Don't use besides much power or it'll be too blurry though.

• Question

  What do I do if the planet images are crystally, and I can't go a clear paradigm showing features and colors?

  

  Make sure you aren't in a light polluted area beginning, but if that's non the instance, exist very conscientious in your focus aligning. Usually a "crystally" expect could either mean humidity / dew in the telescopic or lens or you're looking at a star instead.

• Question

  How do I see the stars through a telescope?

  

  There'southward many stars to meet, and unless the weather is bad, yous can merely point your telescope anywhere during the night sky and notice some stars. Focus your telescope slowly for each new spot y'all view and give it a look. You lot can too try referring to a constellation map if you're wanting to see certain ones.

• Question

  Can nosotros encounter planets in the daytime?

  

  Yep, yous can. Venus is easily visible in the daytime if you know where to expect for it. Jupiter is also visible shortly following sunset or shortly earlier sunrise.

• Question

  What do I do if everything is blurred when I try to see through my telescope?

  

  Using the focusing knobs on the side (usually next to the eyepiece), you can shorten or lengthen the altitude between the eyepiece and lens of the telescope. Suit them until yous see a sharp image.

• Question

  What is the difference between mm in a telescope?

  

  Well, the college the number of mm, the lower the magnification. For instance, 4mm has a college magnification than 25mm.

• Question

  My grandson and I accept become extremely interested in UFOs. What kind of telescope would lend itself to this kind of viewing?

  

  Rather than use a telescope how nearly some loftier powered binoculars? The binoculars are very effective and much easier to apply.

• Question

  On the visor reflector, do I remove the lenses from both ends?

  

  No, removing the side with the reflector on will harm the telescope.

• Question

  Would street lights stop me from seeing things through the telescope?

  

  It's best not to exist in an area that has very bright street lamps when looking through a telescope.

• The eyepiece controls the magnification of the telescope. A select few eyepieces go a long mode towards creating boggling viewing sessions. At first, apply the lowest ability eyepiece (the one with largest focal length number on it, for example, 25 mm), to brand information technology easier to locate objects.

• Familiarize yourself with telescope setup and operation. This is more than hands done during daylight hours in the comfort of your home. Also, while it is notwithstanding low-cal outside, ensure that the finder scope cross-hairs are aimed at the same point equally the primary tube. Use a distant object such equally the tip of a telephone pole to check alignment. Adjust the finder scope as needed as it is essential for locating objects. Information technology's cold after sunset and this is no fourth dimension to exist fumbling with the user'due south manual.

• Dress for success. Nights get dank, fifty-fifty downright cold after sunset. Clothes in layered clothing appropriate for the flavor to brand your viewing session as comfortable as possible.

• Personal condom should be a primary consideration. Be sure to seek permission from holding owners to avert charges of trespassing. Also give consideration to the local wildlife and exist certain yous have taken advisable precautions to avoid disturbing it.

Thanks for submitting a tip for review!
