Am I supposed to see the cross in the centre of image on celestron 76eq

You will see diffrection spikes when focused on a very bright object

and this can also appear around a bright planet. However it is very irritating, and to minimise it, make sure your scope is well collimated (optically aligned).

There is too much to collimation to include here, but there are many guides on the Net

I understand that the image is upside down, but what I am seeing is also "slanted". The customer service rep says I need to ship it back to them, anyone cme up with an answer?

Mirrors are way out of alignment. Your manual does not have "collimation" instructions. I do not know if the user can align the mirrors. If not I suggest you return the scope and get a comparable scope from Meade, Celestron or Orion. If your scope can be aligned, follow instructions at link provided below

Bushnell 78-9003 telescope purchased at yard sale with no eyepiece. Where can I purchase one that will fit? It talks about a .965 inch eyepiece.

.965 eyepieces are readily available on ebay. A meade 25mm MA (modified achromat) is about $10 plus shipping This will give you 700mm/25mm= 28x power. Avoid any eyepiece marked with a H (Huygens) as they have terrible field of view.
.965 is not a popular size anymore and Bushnell does not make very good telescopes. Don't get frustrated, if you are still interested, buy a Meade, Celestron, Orion quality telescope.

Hi, Could you please tell me where I might be able to get my Celestron Nexstar 11 GPS Telescope repaired? The corrector plate needs to be replaced. Is there anyone that could help with this? Regards,...

The scope will need to be returned to Celestron. The Corrector plate must be matched to the rest of the optics inside the tube. This is an EXPENSIVE repair ! Call Celestron here:

When looking through I can see the shadow of the little reflector inside it. We focused in on a star and saw it perfectly but we also couldn't figure out why we were seeing the shadow of the little mirror...

You are not in focus! Was the star ROUND and looked like a donut? Stars are pinpoints of light. They look the same through any size telescope-- exactly the same as without a telescope!

Try focusing on the moon next time.

Can you tell me where i can buy an image erector, thanks

Yes, but it will probably cost almost as much as you paid for the scope:

here is one:

All astronomical telescopes show upside down images, it's normal. The erecting diagonal is only used for terrestrial day time viewing, of land objects.

I have a Celestron Newtonian telescope, 76mm, 700mm. I am trying to locate the finder scope bracket to replace a broken one. I cannot find any other numbers, but it is about ten years old.

Simply buy another finderscope.

Many internet retailers sell finder scopes. Here is Orion Telescope:

Celestron colmination

There should be 2 sets of adjustments to be done. The first is to sight from the eyepiece holder, and see if the diagonal has the back mirror centered - don't be concerned about the off-center of the main mirror. Once the diagonal is centered, then use the adjuster screws to bring the main mirror into line. Adjust first one way then the next (in or out). When done, your eye should be centered in both mirrors. Then align the finder, and away you go.
