Science is simply the act of observing nature and explaining it.  The telescope allows us to make better and more accurate observations, so our science has better facts to work on, and allows our understanding of nature to be more complete.

Your best course of action is NOT to buy a telescope, but find your local astronomy club. The clubs are family oriented & have great knowledgeable people with telescopes. The clubs set up "star parties" where members show the sky to everyone else, especially the new people. People get to know each other while they get to know the moon, Jupiter, Saturn, star clusters, galaxies & the rest of the Universe. While you're making friends & learning the universe, you also learn which telescopes & accessories work best on the celestial objects your family wants to pursue. Therefore, the telescope you buy has a less chance of ending up in the closet unused. Sometimes, if enough people bring food, a real nighttime food picnic starts up too! The clubs also have regular meetings in which professional astronomers & professors from local universities talk about their most recent studies. Its great to learn the Universe with friends instead of fumbling around on your own in the dark.

b) is the correct answer, as others have said. You know, telescopes are a lot easier to understand if you look at a diagram.\n\nYou can find some here: http://en.wikipedia.org/wiki/Reflector_telescope

Astronomy is mostly an observational and descriptive field focusing on sky objects. \nCosmology, is physics applied to the mechanics and functioning of the cosmos. \n\nSo cosmology provides a theoretical background to explain what astronomy sees. \nRoughly, a cartoon would depict an astronomer looking through a telescope, while a cosmologist would be a guy scratching notes on a notepad while using a calculator. Of course, this would be only an approximation. Both use calculators and take notes... \n\n"Astros" derive from "astra", meaning stars. "Cosmos" (the same in greek), means "order, arrangement". And refers to the universe or existence as a whole (including stars, of course).  ;o)\n\nAstronauts and cosmonauts are exactly the same thing. \n\nHope I could clarify it a bit.

I love astronomy. So try nasa.com and look for astronomy picture of the day and it will show you every picture from all the way back to 1996 to today. It's so cool.

Try http://www.surplusshed.com/pages/item/t1423.html\n\nHowever, you are going to be *very* disappointed with the view quality.\n\nThere is no way to turn a camera lens into a "high quality" telescope. Telescope objectives and camera lenses are made for different purposes and to different standards. A camera lens can get by with poorer quality of image because the image is not going to be magnified 200x by an eyepiece. At the same time, a telescope doesn't need to project an image that is flat and large enough to cover the fil, size.\n\nIf you really want a telescope I have two different suggestions to try instead. Go to astromart.com and watch the used telescopes. But the best suggestion is to go to http://skyandtelescope.com/resources/organizations/ and find your local astronomy club. They will have public nights. Go to a public night. You will get to look through a lot of different telescopes. By the end of the night you will know what you want. And, you are likely to come across a very good deal from someone who wants to sell their telescope and upgrade.\n\nhttp://groups.yahoo.com/group/lunar-observing/\n\nChuck Taylor

Astronomy (Greek: αστρονομία = άστρον + νόμος, astronomia = astron + nomos, literally, "law of the stars") is the science of celestial objects (e.g., stars, planets, comets, and galaxies) and phenomena that originate outside the Earth's atmosphere (e.g., auroras and cosmic background radiation). It is concerned with the evolution, physics, chemistry, and motion of celestial objects, as well as the formation and development of the universe.\n\nhttp://en.wikipedia.org/wiki/Astronomy\n\n----------------------------------------------------------------------------\n\nGeology (from Greek γη- (ge-, "the earth") and λογος (logos, "word", "reason"))is the science and study of the solid matter of a celestial body, its composition, structure, physical properties, history and the processes that shape it. It is one of the Earth sciences.\n\nhttp://en.wikipedia.org/wiki/Geology\n\n---------------------------------------------------------------------------\n\nChemistry (from Greek χημεία khemeia[1] meaning "alchemy") is the science of matter at the atomic to molecular scale, dealing primarily with collections of atoms, such as molecules, crystals, and metals. Chemistry deals with the composition and statistical properties of such structures, as well as their transformations and interactions to become materials encountered in everyday life. Chemistry also deals with understanding the properties and interactions of individual atoms with the purpose of applying that knowledge at the macroscopic level. According to modern chemistry, the physical properties of materials are generally determined by their structure at the atomic scale which is determined by the properties and energies of the interactions.\n\nhttp://en.wikipedia.org/wiki/Chemistry\n\n-----------------------------------------------------------------------------\n\nPhysics (from the Greek, φύσις (phúsis), "nature" and φυσική (phusiké), "knowledge of nature") is the science concerned with the discovery and understanding of the fundamental laws which govern matter, energy, space and time. That is, physics deals with the elementary constituents of the Universe and their interactions, as well as the analysis of systems which are best understood in terms of these fundamental principles. Physics is a study of the inorganic, physical world, as opposed to the organic world of biology, physiology, etc. Physics overlaps with chemistry concerning the electro-chemical interactions of substances.\n\nhttp://en.wikipedia.org/wiki/Physics\n\n--------------------------------------------------------------------------------\n\nMeteorology is the interdisciplinary scientific study of the atmosphere that focuses on weather processes and forecasting. Meteorological phenomena are observable weather events which illuminate and are explained by the science of meteorology. Those events are bound by the variables that exist in Earth's atmosphere. They are temperature, pressure, water vapor, and the gradients and interactions of each variable, and how they change in time. The majority of Earth's observed weather is located in the troposphere.\n\nMeteorology, climatology, atmospheric physics, and atmospheric chemistry are sub-disciplines of the atmospheric sciences. Meteorology and hydrology comprise the interdiscplinary field of hydrometeorology.\n\nhttp://en.wikipedia.org/wiki/Meteorology

Looks like you need to read the documentation on the website.  Is does say that it's all simulation mode for now, so you're not actually controlling the telescope yet.

Optics - microscopes and telescopes all invert the image because if they didnt, it would mean that another lens had to be added, increasing money cost. A lens is convex on both sides. That means the middle is thicker than the edges. A microscope or telescope has two lenses (basically).\nThe objective lens (usually larger and closer to the specimen or object) which allows the image of the object to be reduced to a smaller workable image inside the scope. This image is inverted inside the scope. It is also too small to see with the eye, so you need another lens, the eyepiece.  The eyepiece focus's your eye on the image and magifies it so you can see it. Every lens has a focal length, the point at which the image is formed away from the surface of the lens.

No, I read an article and it said that you need a strong telescope and lots and lots of astronomy experience. I was hoping I'd be able to see it too, but I have neither!

For most operations, the telescope uses reaction wheels.  These are gyroscopes on motors.  If the telescope wants to pan in one direction, it speeds up a reaction wheel in the opposite direction, and conservation of angular momentum ensures that if the wheel spins faster counter-clockwise, the telescope spins faster clockwise to compensate.  Once the correct angle has been achieved, the reaction wheel is spun back to its normal speed, and the telescope stops panning.  This method is much more precise than rockets which would usually have to burn continuously to hold a stable attitude, polluting the vicinity with burned materials which can interfere with imaging or degrade the mirror by accumulating on it.\n\nOver time, external torques can pull the telescope out of alignment, requiring the reaction wheels to spin faster and faster to keep it steady.  Eventually they reach their maximum rotation rate, and something has to be done.  This is done by "reaction wheel desaturation".  Only at this point do the rockets on the telescope fire up and apply a torque which lets the reaction wheels be spun back down to their normal operating range.  The telescope can't do any science while the rockets are firing.\n\nThe pointing accuracy and stability of the telescope are controlled by locking onto guide stars.  It has specialized instruments that let it control its orientation by measuring the location of known bright stars.

Hi, great question.  I got a new telescope a year ago and have found a couple of excellent sites.  First try 'skyandtelescope.com'  this site has several features including a sky chart.  Enter your info, and it gives hour by hour info on whats up there to see, as well as info on upcoming events.  It offers 'how to advice' for telescopes, binocs and  astro photography.\nThe second is 'astromart.com'   this is one of THE BEST and most helpfull sites I have been to.  What a great forum.  Several active members are well known scientists and professors as well as very knowledgeable amature astronomy buffs.  No question is to stupid for them and you won't find a better place to gain advice and knowledge.   Questions posted are answered very quickly, usually in no more then a few hours, sometimes immediately.  Try both of these, I'm sure you will find what you need.    They are both  free of charge, believe it or not!!!\n\nLet me know what you think,  my s/n on astromart is lilkritter!!  Good Luck!

It depends on what you need telescope for.  Things like Jupiter, Saturn, the Moon, the Orion Nebula will look great.  This is a great out of the box scope but it isn't a large one.  If you want to do a lot of deep space exploration you need a bigger/different scope.  There is an article at Sky & Telescope about chosing the right scope.\n\nhttp://skyandtelescope.com/howto/scopes/article_241_1.asp

i believe it's the magnification (or other distortion such as increased brightness) of the appearance of a star in the sky or through a telescope. the diffraction can be eliminated digitally, but other than that i'm not sure.
