Question about Edu-Science (10166) Telescope
If you are satisfied it is well collimated, then:
- did you use a laser collimator? If so is THAT collimated? Lots of them are not.
- check all the adapter rings, diagonals, barlows etc that you might have are all properly seated
- then, I'd say your main mirror securing clips are done up too tight and are distorting the mirror. They should only just touch lightly.

SOURCE: Problem with image
Stars are blurry period thats just the way they are. and with the worlds atmosphere (air) you'll always get a slight waviness...even when viewing planets.

Dopn't worry about upside down. All astronomical telescopes show images upside down. There is no up or down in space.
You may have what is called an "erecting" prism diagonal that turns the image right side up. Just Google "erecting prism diagonal".
This may also help you.

The mirror is BEHIND the metal "spider" pointed toward the main mirror in the bottom.

All astronomical telescopes show upside down images-- it's normal. Put the eyepiece with the largest number written on it into the focuser. DO NOT USE the 2x barlow if you have one.

The bit you are missing is the finder scope, which is a small low-power scope that is used to line up the main scope on an object that you want to view. Without this it can be quite hard to get the scope pointed at anything, as the field of view is quite limited, and more so at higher powers.
It can be quite expensive to buy useful eyepieces for a scope, but they are readily available if the eyepiece mount tube is 1.25 inch inside diameter. The eyepieces that originally came with this scope probably were not very good, and in fact this scope is not up to much. It is rather small for a reflector at three inches diameter. You certainly won't be able to use it at the advertised 600 power, or even at 200. It has neither the resolution nor the light gathering ability with that small an aperture.
I would recommend that you explore the web page at THIS LINK for a lot of good advice about first telescopes, before you spend any money.
