Can not seem to focus when we look through the

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
