since some models change the size of the eyecaps they use ,your best bet is to take off the other side and mail to bushnell for a proper match

The first number is the magnification the second number is the size in millimeters of the objective (large lens) So if you measure the diameter of the front large lens that will give you the size. So a 10x50 means a magnifyng power of 10 and an objective of 50mm.
Now to find out the magnification if you don't know what it is. Measure the front lens. Then if you look through the eyepiece lens while holding it away from you you will see that there is in each a small circle of light. That it what is known as the exit pupil. It lines up with the pupil of your eyes when you have the binoculars pressed up against your eyes. Now measure the diameter of the exit pupil in millimeters. It will only be a small number.

To work out the magnification use this formula. Magnification = Objective size divided by the exit pupil.
So a 10x50 will look like this M = 50 divided by 5....therefore M =10 which is the magnification.

Both the 7x35 and 10x50 will have an exit pupil of 5mm. So if yours is one of these then all you need is the objective (large) lens size.

### Can not seem to focus when we look through the lens we just see the bk=lack sky we cannot seem to see anything

try this:
see the mini scope on top of the telescope?--that's called the finder scope--
you look through that to see what the telescope is aimed at, just like what a sniper does before he pulls the trigger.

put in the lowest power eyepiece you have in the telescope, the one with a high number on it.

it's a good idea to align the 'finder' with the telescope during the day time--it's much easier.

if your telescope and finder scope aren't aligned properly, aiming your telescope at any target will be off and you'll just get frustrated.
to do this, look through your finder scope and pick a far away target, put in the lowest power eyepiece you have, that's the one with a high number--
high number = low power = a nice big view in the telescope.
low number on eyepiece = high magnification, like a zoom lens.

always use the lowest eyepiece first, then work your way to higher magnification, if you want to get a closer look at your target.

use lowest power eyepiece in telescope--> look through finder scope -->focus the image--> switch to higher power of eyepiece for a closer look at your target.

practice this during the day until you're comfortable, then try it at night.
try the moon, it's a nice big target

you can also use binoculars to check out the night sky.
you can try using 7x35 or 7x50 binoculars.
you see a lot more stars and it gives nice big views of the stars and constellations...and the moon...

hope this helps :D

### Can't get the telescope to focus on anything.

First here are the manuals for all the Bushnell telescopes-- which you need to read cover to cover--

http://www.opticsplanet.net/bushnell-warranty.html

Now put the eyepiece with the LARGEST number written on it into the telescope-- this will give you the LOWEST magnification. Go outside during the day and practice focusing on a distant land object-- the moon should be your first target at night.

### Bushnell insta-focus mechanism gets stuck.

they were famous for that, because the screwpin that holds the eyepice shaft is metal and the groove that it rides in is plastic, and eventually gets jammed....look where you put your fingers to adjust eyepieces. should be small metal plate in center of hinge(sometimes with bushnell logo) that will simply pry off by using small screw driver,and now you will be able to see if the screw is loose or damaged. good luck...larry@reichinstruments.com
