Where can I find an instruction manual for edu science land and sky 360 (50mm refractor) telecope?

You can only use the eyepiece marked 20mm. This is a toy not a scope and you will only hate astronomy if you try to use it. The tripod is unstable and the lenses are plastic. Send it back and get a quality scope from Meade, Celestron or Orion. Orion makes a tabletop Dob (only 76mm aperture) for about $60 that is much better quality.

You will need to experiment replacing the lens in various configurations to see what works.

Next time NEVER disassemble an eyepiece or a telescope lens. Only the outside surfaces ever need cleaning.

Any photo tripod would work if you can attach the tube. Toys R us do not provide any instruction manual, and they do not sell parts.

We receive the most complaints on this brand. It is really a TOY telescope. Sorry.

Yes -- eyepieces come in 3 sizes .965, 1.25, and 2 inch sizes. Measure the hole in the focuser and buy the correct size.

Here are two retailers:

You cannot get a manual for that small telescope being sold by Toys R Us.

The manual would only have assembly instructions it will NOT tell you how to use the scope to see objects in the night sky.

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.

The end with the focuser. Then put the eyepiece with the largest number written on it into the focuser. I believe this model is a REFLECTOR, if it is there is a mirror in the bottom of the scope.

REFRACTORS have a lens in the front of the scope.

Then read my Frequently Asked Questions TIP on my profile page. The picture you selected shows a REFRACTOR telescope.

You will not find a manual for that telescope. However Meade maintains a web site for their telescope manuals. Look under REFRACTOR or REFLECTOR for one similar to your telescope. They all go together in a similar fashion.

Many people have the same problem-- with these small telescopes you are stuck with seeing only the moon, and several other planets, and maybe a few bright star clusters.

These are all TINY objects (except for the moon).... when you look through the telescope you are looking at a section of sky about the size of your fingertip held at arms length-- the scope must be pointed DIRECTLY at the object. Practice on the moon first-- and then try to find Saturn which is up in the sky right now-- it looks like a dim (slightly yellow) star.

This is a small refractor telescope-- they pretty much all work the same-- BUT don't expect to get more than 100 power out of the scope. Yes I know the box said 600 power but it's a lie. In my 8 inch telescope I rarely get above 250 power and my scope is many times larger than the one you have--

Now put the eyepiece with the largest number written on it into the telescope-- the LARGER the number the LOWER the magnification. During the day time practice focusing on a distant object --- AND line-up the small finder scope on top with the main telescope tube. Look at the top of a distant light or church steple, or telephone pole. Without moving the telescope adjust the small finder scope by loosening and tightening the screws around the tube holding the finder scope-- put the crosshairs on the same spot as the main telescope.

Now you can use the small finder to locate objects in the sky-- the moon should be your first night time target.
