Yes, all astronomical telescopes show upside down images--- no up or down in space!

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.

Astronomical telescopes usually show an upside down image. There is a good reason for this- erecting the image needs more bits of glass in the light path, which reduces the amount of light and increases aberrations. Even if this is only slight, astronomers prefer to avoid it, and they don't really care which way up the Moon or Jupiter appear. It is possible to fit an erecting prism or eyepiece to most astronomical telescopes, and some of them come with one, but one wouldn't bother to do this with the small finder scope.

As for the lack of an image in the main scope, and assuming you haven't merely left the dew cap on (like a lens cap on a camera), this may be the result of using too high a power of eyepiece. The higher the power of eyepiece on a telescope, the dimmer the image, the more difficult to aim it at any chosen object, and the more difficult to focus. It is best when you are starting out with a telescope to try it with the least powerful eyepiece (the one with the highest number) to begin with, until you become more familiar with how it works. Do NOT use the Barlow lens if one came with the scope. Try to point the scope at an easy to find bright object like the Moon (never point a telescope toward the Sun!).

Once you have the light of the Moon coming through the scope, you can find the focus point for the eyepiece by turning the focusing knob. There is a very wide range of movement in the focus mechanism, because different eyepieces focus at different points, but the actual focus range for any eyepiece will be a small part of the overall range afforded by the focusing mount. You will also find the the object you are looking at swims out of the viewing field, and you must continually move the scope to follow it. This will be more pronounced at higher magnifications.

It is unlikely that the finder scope will be much use in pointing the telescope until you adjust it to precisely line up with the main scope. Most manuals recommend that you do this in daylight, by pointing the scope at an object on the horizon and adjusting the finder to match.

Take it back where you bought it. We receive more complaints on that scope than on any other brand.

Yes, all astronomical telescopes invert the image-- it's normal, nothing is wrong with the scope.

All astronomical telescopes have reversed images-- it's normal nothing is wrong with the telescope.

You must have a REFLECTOR style scope with a MIRROR in the bottom. The focuser end is the UP end -- the mirror is on the GROUND end.

You probably have it mounted backwards.

It should look like this:

There are no manuals for that scope which is sold by Toys R Us.

If it is a refractor scope, that is normal. In fact it is normal with many types of scopes. You can get a prism that will turn the image over to make the image be upright. Most astronomers just go with the inverted image.

No up or down in space. :)

Sorry there are no manuals available for this telescope being sold by Toys R US. Maybe the store has one you can copy. Why not locate an Astronomy club nearby and have the members help you with the scope.

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

It's not worth hunting down that many parts for that small telescope. You cannot just buy a tripod leg-- you must buy the entire tripod. Eyepieces cost at least $30 each-- and a finderscope at least another $30-$40.

Locate another complete telescope. It's not economical to repair that low cost small scope. Toys R Us who sell that brand do not furnish replacement parts.

Eyepieces come in 3 sizes .965, 1.25, and 2 inch sizes. Measure the hole in the focuser and buy the correct size. The .965 size is hard to find.

No manuals are available for that small telescope. Those are being sold by Toys R Us contact them and see if they have a manual-- I doubt it!

Yes, but the ones for sale are all metal and not plastic like the ones that came with that scope (sold by Toys R Us).

They may cost more than what the entire telescope cost you.

Eyepieces come in 3 sizes --- .965 inch, 1.25 inch, and 2 inch. Measure the hole in the focuser. The .965 size is a little hard to find since most commercial telescopes use the 1.25 inch size.

I believe the eyepiece on the Eduscience scopes is the standard 1.25 inch diameter size. These are widely available, you don't need to get any particular make. They will come in different magnifications, from about 4mm to 20mm, with the smaller numbers being the more powerful (and least practical on these scopes). Try a search on Amazon or eBay for "eyepiece".

DO NOT buy an Edu Science telescope. We receive many complains on these scopes.

Try this web site for a nice small Dobsonian style telescope, like this one.

They do not sell replacement parts for that "toy" telescope-- which is being sold by Toys R Us.

You might be able to find bolts - nuts-- etc etc at a well stocked hardware store.

You will not find a manual for those EDU Science scopes being sold by Toys R Us. Also you never said what style of telescope you have so we can help you. Iws it a reflector or a refractor?
