Recently, I have got stuck in interest of discovering the beauty of the sky. And it decided to buy a telescope. I am entirely novice in that part of science. I would like to know the abc of telescope.

I would suggest holding off on a telescope initially. Start with a good pair of binoculars - 10x50. It's amazing what you can see with just those. You can even see the moons of Jupiter. And the Andromeda galaxy. Get a map of the night sky, and start exploring. When you're ready, read up a lot on the different types of telescopes - refractor (most expensive), Newtonian reflector, Schmidt-Cassegrain, etcetera. Then, make sure to get the one that suits your needs. There is always the temptation to get a bigger one that you will consistently use. If you get a 10" reflector, and it sits in the house because it's too unwieldy, you just wasted a ton of $$$. Better off with a 6" that you'll take out and use. General suggestion would be a Meade or Celestron 8" with star tracking technology. There's a lot of on line resources to use. And, there's pretty good catalog called Orion. Also on line. Good luck.

A 4" rich field reflector is a good telescope for a beginner. Although it's limited to low powers, its wide angle view and light gathering abilities make it excellent for studying comets, star clusters and nebulae. Be sure to investigate models with a clock drive, which facilitates observations by tracking objects as the earth rotates. It's important to get some hands-on experience with a beginner's telescope before investing in more expensive models.

Beginner's telescopes usually come with three or four eyepieces: 40x to 300x. An instrument of this size has an upward limit of about 100x. You start losing image definition if you exceed. The telescope companies have to make their profit and are not always above selling you eyepieces that you don't really need. It's a good idea to buy an extra eyepiece of about 20x or 30x for wide angle viewing. You don't have to exceed that power when studying comets and most star clusters.

Unfortunately, I can't recommend any particular brand of telescope. It's been nearly three decades since I owned my own observatory.

You should also check Amazon for beginner's books on backyard astronomy. Pat's suggestion that you start off with a good pair of binoculars is sound and practical. This is exactly how I started out when I was still in grade school. A reclining lawn chair and a blanket come in handy when observing the night sky with binoculars.

I tried one a few years ago in Texas and could not get used to it. All it did was make my head spin, so I gave it to my then girlfriend's son.

If you can afford it, I suggest you get a reflecting rather than a refracting telescope. I bought a refracting telescope for cheap. And I have to admit, it is almost useless

I don't understand t difference. But w binoculars, it seams as if t entire image is clear. W my scope tho, there was only a tiny sweet spot. I understand reflecting scopes were developed so as to alleviate just that problem.
