Bushnell voyager sky tour 700 mm x 3" missing

You have asked a loaded question like "what size is a grey suit".

You need the focal length of the telescope divided by the size of the lens. Say 700 mm divided by 12.5 mm = 56 power. That said how close do you want to get to it? And how steady is your telescope?

Did you set it up according to the provided instructions?
Do you have a low power eyepiece inserted at the viewing end?
Have you aimed the telescope at the moon as a basic test of
visibility?
If your telescope is not properly aimed at the target (a star or a planet, or other object in the night sky) then you will see nothing.
If the power of your eyepiece is too large and your telescope aim is
not "dead on", then you will see nothing.
Have you tried using the scope in the daytime? Do you see anything?
Aim at a specific object, or section of an object, like the top of a lamp-post about a block or two away, and see if you can focus on
it the eyepiece.
You really need someone at your side who has experience in using
astronomical telescopes. That would be the quickest way to solve
any problems you have.
Unless your question is very specific, and unless you provide as
much detail as possible about your problem, it will be difficult for
anyone to provide you with speecific answers that will help you
solve your problem.

YOU THINK? and what piece do you "think" you are missing. How can we answer an incomplete question, with no description of the problem.

TOO much magnification for that 3 inch telescope. The most you will get is about 120 power or so on perfect sky nights. Try a 10mm or 9 mm as your most powerful eyepiece.

50 times aperture is the maximum possible.

Most of these small telescopes do not have an operators manual-- however Meade maintains a web site for the telescopes with manuals. Find one similar to yours and download the manual for free.

It does NOT keep time! You enter the time AFTER you turn it on.

There are a bunch of Sky Tour telescopes ---

which model you actually have??

I am assuming you have what is called a Dobsonian mounted reflector like this one:

Is that correct?
