    Not normally. Do you mean that you can see the spider holding the secondary mirror?Or that there is a cross hairs in the eyepiece view?

    The spider, I guess I'm trying to zoom in to much, it's only when I'm trying to view planets, not sure how much or how little im supposed to see?

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

What is the switch for below the viewing lens on a Celestron Astromaster EQ76 telescope?

Your picture is not very clear. However there is a complete setup video located here. I did NOT notice any switch near the eyepiece; only the thumbscrews used to hold the eyepiece in the focuser.

USE only the eyepieces do not use the 2x barlow. Try again with just the eyepieces starting with the one with the largest number written on it. Focus slowly until you get a sharp image-- you can practice during the day time on a distant object.

Telescope view

It's not in focus--- turn the focus knob slowly in and then out until you get a sharp image....... use the lowest magnification eyepiece first-- that's the one with the LARGEST number written on it.

Obscured view through telescope

You can slow down dew forming on the mirror by NOT pointing the telescope toward the sky during cool-down-- just leave it parallel to the ground. Same goes for your eyepieces -- leave them covered, or inside a case.
