I wanted to know the method to build our own telescope. The materials required as well as the procedure to be followed.

The first link below is a Web site that has instructions on how to build your own telescope. You should also look at the second link, which is for Edmund Scientific. Edmund has all sorts of supplies and kits to build telescopes.
Finally, your local library will almost certainly have a book on building a telescope. Read one and see if this is still a project you'd like to do.

STEP 1: Acquire a pair of lenses - a large convex lens and a small concave one. (Convex lenses are thicker in the center than at the edge; concave ones are thinner in the center.)
STEP 2: Find two cardboard tubes that will allow one to slide inside the other.
STEP 3: Figure out how far apart the lenses should be by looking through the smaller lens while holding the larger one out in front of you. When you can focus on an object in the distance, measure how far it is between the two lenses.
STEP 4: Double that measurement. The length of the two tubes should be about this long.
STEP 5: Fasten the larger lens on one end of the wider tube. Hot glue is good for this.
STEP 6: Mount the smaller lens at the opening of the smaller tube. This is the eyepiece.
STEP 7: Build a gasket from cardboard or Styrofoam if the tube opening is larger than the lens.
STEP 8: Make sure the lenses line up with each other. The centers should be in the centers of the tubes and the lenses should be parallel with each other

The only basic requirements are two lenses with different focal length and a way to mount them. The lens with the shorter focal length will be the eyepiece. The more difference between the focal lengths, the more powerful the telescope will be. To compute the power of a telescope, divide the focal length of the objective lens by the focal length of the eyepiece lens.

There are a few ways to do this but you have to answer a few questions first.
1. What kind of telescope do you want to build? A reflector? A refractor? A catadioptric?
2. Do you want to make it completely from scratch and grind your own optics or do you want to buy the parts or a kit and assemble it?
3. If you want to grind your own mirror/lens, do you want to buy a grinder to do the "hogging out" or do you want to do it by hand?
4. If you do want to make your own mirror/lens, do you have the place to do it?
Mirror/lens grinding is labor intensive but many astronomical societies offer mirror grinding workshops. Sometimes they provide the glass for a fee or you can buy it from http://www.newportglass.com
If you want to buy the mirror, you can get one from http://www.scopecity.com they sell Parks mirrors I think
http://www.rfroyce.com high end, pricey
http://www.e-scopes.cc/Murnaghan_Instruments_Corp56469.html
The last is affordable
You should also visit http://www.atmsite.org
This is a clearing house for amatuer telescope makers and there are many resources here and people to consult with.

This is just a caution , if u live in the city ,the lights will blind the telescope , and u will be disappointed .
