questions about Celestron NexStar 130 SLT Computerized Newtonian Telescope…?
well, i got a telescope from wal-mart, it’s called Celestron NexStar 130 SLT Computerized Newtonian Telescope. then here’s the problem that i have, when i look to the sky, it’s all dark, i thought that i can see all the beatuiful stars and galaxys. so this is the problem. also, tonight i looked at a star, a pretty bright one, but all i see is just a star, i can even see with my own eye, and also said that i can see the saturn with all the rings, and also jupiter withthe great red spot. but it didn’t because i don’t know what happened to the telescope. you know it’s very weird. so can you tell me what to do? should i need to return it and buy it from a different store or anything i can to. so please tell me. thanks
i mean that i thought that i can see all the galaxys in the sky
Many beginners have unrealistic expectations of what a small telescope will show them, based on what they’ve seen in books and magazines and the internet. The stars are all so far away that no telescope, not even the Hubble, will show them as disks. Any telescope will let you see stars which are much fainter than you can see with the naked eye, but they will all be nothing more than points of light. The planets are also far away, and much smaller in size than people expect. Much detail can be seen in them, but that depends on training your eye to see that detail.
Some specific things:
(1) Saturn is currently at the point in its orbit where its rings are edge-on to the Earth; that happens twice every 29 years. Its rings will be better next year.
(2) The Great Red Spot on Jupiter goes through changes in the intensity of its colour. It has been the “Great Pale Spot ” for the last decade or so, mainly visible by the gap it causes in the South Equatorial Belt. It also is visible only about 25% of the time because of the planet’s rotation. Even at the best of times, it usually takes a year or more of careful observation (eye training) before the Red Spot can be seen in a telescope your size.
(3) Galaxies (and other deep space objects). They’re out there and can be observed with your scope. Several things are required. First, dark skies. I mean inky black country skies. Galaxies are really faint and need all the help they can get. Secondly, you need to know exactly what you’re looking for, and exactly where it’s located. Most of space is, well, empty space…nothing to be seen there with a telescope. You need a good star atlas (even though your telescope has GoTo) to exactly pinpoint the object’s location. Then you need to adjust your expectations to look for the faintest wisp of smoke. In fact, many beginners simply cannot see deep space objects at first, no matter what telescope they’re using. It helps to start with the brighter targets, such as Messier objects like M81, M82, and M104. Finally you need to learn specific observing techniques like averted vision.
So, my friend, the problem is not so much with your telescope (though a larger aperture would help), but with your eyes and lack of experience and eye training. My article below will give you more information on what to expect in a small telescope.
