DID you mount the telescope BACKWARDS? The large mirror is on the bottom of the scope, the focuser on the side of the tube is on the UP end of the tube. I have seen many beginners mount these with the actual open end of the tube pointing at the ground!

Take the scope outside during the daytime and put the eyepiece with the LARGEST number written on it into the telescope. Practice focusing on a distant object.

At night the moon should be your first target. Remember that objects in the night sky are all smaller than the tip of your finger held at arms length. The scope must be pointed directly at them in order to see anything in the eyepiece.

    AND your scope will never reach 575 power magnification. Why? Because the maximum magnification of any telescope is about 50 times aperture. Your scope is about 4 inches in aperture so 200 power is the most you will get. Magnification is the least important factor in a telescope.

    Aperture and quality optics are much more important. They lied on the BOX when they said 575 power. This is just one indication that it is what we call a "department store" telescope.

    Just a comment for the OTHER folks viewing this answer. NEVER buy a Tasco, Bushnell, or Vivitar brand of telescope. These are ALL not suitable for the Astronomy hobby.

    You cannot buy a useable scope for less than about $200; just like you cannot buy a useable computer for less than $200. Please stop buying these toy telescopes on Ebay, Wal Mart, and craigslist!

Light enters the front of the tube -- TAKE the lens cap off-- goes down to the bottom of the scope and its the primary mirror--- then bounces back up and hits the tiled secondary mirror which sends it OUT to the side into the focuser and the eyepiece. The largest the number on the eyepiece the LOWER the magnification. Start with your lowest magnification until you learn how you focus. Try this during the day time on a distant building or telephone pole.

POINT THE END with the cap toward the sky. The mirror is on the bottom of the scope. Then put the eyepiece with the largest number written on it into the focuser, practice focusing on a distant object during the day time.

Hate to tell you, but we receive more complaints about this brand of telescope than any other!

Is this a REFRACTOR with a lens in the front, or a REFLECTOR with a mirror?

Any well stocked hardware store can supply you with the small thumbscrew that hold on the eyepiece. BUT this scope is being sold by TOYS R US! What does that tell you about it!

Next time buy your grandson THIS telescope:

Practice focusing during the day on a distant object at least 100 yards away-- use the eyepiece with the LARGEST number written on it-- and DO NOT use any 2x or 3x barlow to multiple the power.

The moon should be your first target at night.

Im trying to find out to put my telescope together just got it but no directions any help please

You did not say what brand and model number--

However-- Meade telescopes maintains a web site with the manuals for all of their telescopes. Find one that is similar in style to your telescope and use it to learn about how to assemble yours.

There are really only three styles of telescopes reflector (with a mirror), refractor with a lens in front, and catadioptric with a lens in front and mirror in back--

and only two kinds of mounts-- ALT AZ (up down left right) and equatorial (usually has a counter weight and needs to be polar aligned)-- the general instructions are usually about the same--

Here are the manuals-- which usually include how to use a telescope--

Try the refractors and reflector manuals first--

Good luck-

Upside down images

ALL astronomical telescopes show upside down images it is normal. Put the eyepiece with the LARGEST number written on it into the diagonal. Do NOT use the 2x barlow it is too much magnification for that small aperture telescope.

You never said if this is a refractor or a reflector (with mirrors). If it is a refractor you need to collimate the from lens cell-- this is fairly difficult without an optical bench.

If you have a reflector with mirrors then watch this video to learn how to collimate a reflector style scope.
