Just got a 78-8831 and set it up according to instructions. After inserting lens into eyepiece, I can't see anything at all. Dont worry, I've removed the front cap from the the main telescope.
Something leads to believe I'm either missing something real fundamental or my telescope is broken. Please help
I cannot see anything either. I've spoken with several people where it was bought and they assure me that everything is set up corretly. I cannot find and telephone number to call someone for assistance.
In addition.... you can download the complete manual immediately here :

Hello sir
If you dont have any experience with telescopes, I suggest trying it
first in daytime, since daytime objects are much better for getting
experience. Also, start with the lowest power eyepiece,
the one with the largest lens. Start by looking towards something
pretty big, like a car or a house, and it needs to be some distance
away to even have a chance to get a focus. If your target is closer
than about 1/4 mile, you should add the right angle eyepiece attachment
to allow you to focus in on closer objects.
When you are finally
set up with the low power eyepiece, and have a good big target in the
daytime, start looking thru the telescope while turning the knob thru
the entire range. At some point of knob turning, you should see some
image appear in the eyepiece..Turn the knob slowly to focus it clearly.
And
this is for the shaky tripod. If you can hang a book under the middle
of the tripod, the added weight will help stabilize the telescope, and
you should be able to see a little better, without so much motion at
the slightest touch.
After you look at the first car or house,
you can see how careful you have to be to use the telescope,
and you can start to look at other objects. When you move to the higher
power eyepieces, it will be even more critical in getting it both
aimed and focused. If its off by just a few degrees, you wont see what
you are looking for.
When you start nightime viewing, start with
the largest object in the sky, the moon. Its the same process as
daytime, except the eyepiece mechanism will have to be adjusted a
little closer to the main body of the telescope.
Viewing planets
and stars will be the ultimate test. Stars and planets are harder to
see, since they are small, and hard to see unless they are in focus.
When you can see those views, you have passed the telescope test. Its a
matter of careful aim, and having the telescope focus set close to the
point where you can see objects that are VERY FAR AWAY. If you are able
to focus on the moon, you will be fairly close to being able to focus
on the planets. The hardest part is actually getting the planet in the
view of the telescope, in other words, aiming it.
The last item
that can really mess up the view is a fogged up lens. Usually this
happens in the summer when the scope has been in the air-conditioned
room, and then it fogs up when taken outside. The solution for this is
to let the telescope sit outside for 20 minutes, so the fogged lenses
can clear. By the way, the same fogging may happen when you bring the
telescope inside during the winter.
I hope this helps you
eventually get a clear view of some amazing views in the sky. Your
final exam is to take a look at the moon, the rings of Saturn, and the
moons of Jupiter, some time in the near future. Have Fun!

As we all learned in grade school, telescopes produce an upside down
image - it's okay for astronomical use since upside down doesn't
matter. If you want an image like you'd see in a pair of binoculars,
get an image erector from a telescope accessory store to add to your
eyepiece.

Hi Rnska
If you dont have the manual and you wish to take a look at it, you can get it here. You will have to register (at the right) you can fill it with fake info if you want, then you will be able to download it.
Do you at least can see some light trough the part where you put the eye? if you cant see a light, then setup is wrong and there is something blocking your view...
otherwise.. it needs to be refocused... maybe you arent pointing it to your target correctly...
try pointing it to the moon (since its big and hard to miss) then, if you get some light (no matter if its blurry or not) start focusing and maybe cleaning the lens...
good luck with that.. hope that helps
Do you see only black image when you look trough it?
This would be difficult to answer without being there to check it out
myself. however be aware that if it is a reflector scope the angled
mirror on the inside may have a protective cover over it, or it may be
angled wrong, if you had to assemble consult the directions again. Also
the finder scope may not be in line with the main . try removing the
view lens and moving in little circles tword the moon you may notice
lite on the inner wall of the scope. if its a refracter the its
defiantly miss alignment between finder and main try a day lite target
and the adjust the finder and main in both instances before it gets
dark, hope that helps . Also you could try finding a lit in your
neigbor hood like a street lamp and with the lowest mag lens try to
align your finder too the main
You say the lens cover is off, but is it _completely_ off? Many
telescopes come with a two-part lens cover. If you've only removed the
middle part, the light will be blocked from reaching the primary mirror
by the secondary mirror. When the lens cover is completely removed, the
hole in the end of the tube should be as large as the tube itself.
Another possibility is that the secondary mirror is rotated out of
position. If you look in the focuser without an eyepiece in place, you
should see the secondary mirror. On that you should see a reflection of
the primary mirror, and in the centre of that, a reflection of the
secondary mirror, and within that a reflection of your eye. All should
be concentric. If not, first adjust the secondary mirror, so that the
reflection of the primary mirror is centred in it, then adjust the
primary mirror so that the secondary is centred in it. This is called
collimation. Check the source for more details and illustrations.

I can now see things through it but they are upside down. What can I do to fix this
