EBay !

All Refractor Telescopes are the same. Take a look at any of these in the second link, but this one is yours with a different name of the seller.

Sorry -- This is a Discovery planet telescope. Only the retail store will have a manual.

Try to locate a Discovery store?? here is their web site:

You cannot -- parts are not available for this small imported telescope. You might be able to find a regular photo camera tripod that would work.

There are 3 types of telescopes --- see this web site:

http://texasastro.org/telescope.php

and two types of mounts--

Altitude- Azimuth and Equatorial
http://texasastro.org/mounts.php

You must be more specific as to the type and the mount.

You cannot-------- this scope is being sold by Toys R Us and no replacement parts are available.

No one will have a manual for this telescope, However here is a picture:

This is a very simple refractor on an alt az mount. Sure wish you had NOT bought this "department store" telescope. It will be shaky and has a very small aperture. Read my TIPS on my profile page to find out how to improve a department store telescope.

You can buy a diagonal and finder-scope from many on-line retailers. You may need a .965 inch diagonal. Measure the hole in the back end of the telescope.

Diagonals are made in 3 sizes.... .965, 1.25, and 2 inch sizes.

Here are two retailers-

You are about the 10th person to ask for this. These are being sold at Toys R Us and the "toy" really applies to this scope. If you can return it and buy this telescope for your child.

and no you cannot buy a usable scope for less than $200. No manual exists for your telescope, however Meade maintains a web site of manuals for all their telescopes. Look under the REFRACTOR heading on the below web site for one similar to your telescope. They all assemble about the same way, and Meade includes a section in the back of all manuals on how to use the telescope.

This one is similar to your telescope.

Do NOT use the barlow lens-- put the lowest magnification eyepiece into the scope-- practice focusing on the moon -- turn the focus knob slowly in and out until you get a sharp image.

Telescopes only show an area of sky about 1 degree wide or LESS--- this is about the size of the TIP of your finger held at arms length................ your scope is best used at low magnification.
