Bushnell Voyager 78-9470 (470 x 60mm) Telescope Questions & Answers
Brother knocked our telescope over & jarred it out of alignment. how to realign?
This is a refractor telescope that normally never needs collimation (optical alignment) More than likely the focal tube got knocked out of alignment or the diagonal mirror was shifted. I believe the objective lens is glued in so there is little you can do there. Pull out the diagonal and focus tube, check the focus tube for roundness and that it moves in and out smoothly. If the diagonal mirror looks skewed to the eye, find a cheap replacement on EBAY.
Do i need anything special at night table top
All telescopes have very small fields of view-- it must be pointed directly at the object in the sky or you will not see anything. Simply put the eyepiece with the largest number written on it into the focuser-- then during the day time practice focusing on a distant object like a building or telephone pole.
The moon should be your first target at night.
One answer advises NOT to use the "barlow." A
A Barlow lens doubles (or trebles) the magnification, but it also degrades the image. You are better off without it. People tend to buy telescopes on their magnification figures, even though these are essentially meaningless, so junk like Barlows get added to the package to increase the advertising impact. The mere fact that one came with this telescope tells you that the quality is not wonderful.
The specification that means something in a scope is the diameter of the objective (the main lens or mirror). Magnification is just the focal length of the objective divided by the focal length of the eyepiece. You can usually see more at lower magnifications, as the resolving power of the objective is often less than the advertised magnification. A smaller distinct image is better than a big blob of fuzz. That's why you were advised to try the scope first with the larger number (lesser magnification) eyepiece.
But try out the Barlow and see for yourself.

Voyager 78-9470 (470 x 60mm) Telescope: we have never had a telescope, got it from a frien...
This is a small REFRACTOR style telescope. Put the eyepiece with the largest number written on it into the telescope. DO NOT use the small lens that says 2x (barlow) on the side.

so you understand what the different types of telescopes look like when setup correctly. Bushnell has a web site with all of their current manuals here:

Look down the web page and find your telescope and download a manual. Read my TIPS on my profile page.
Can not see thru telescope.
Yes it will focus --- put the eyepiece with the LARGEST number written on it into the scope. DO NOT use the 2x or 3x barlow.
Practice focusing on a distant object at least 100 yards away during the day. The moon should be your first night time target.
Eyepiece assembly bushnell telescope
You never told us what model number or telescope TYPE you own. Is this a refractor or a reflector. ???
If a REFRACTOR usually you have a diagonal, the diagonal goes into the focuser and then the eyepiece goes into the diagonal.
On a REFLECTOR the eyepiece goes directly into the focuser.
