I have a galaxsee 525x - was given to me a few days ago. It has been used and came with no instruction manual. I have out it together but I cant see anything with it. I can when I dont put the lense in but when I put in the lense I cant. I can see through the lense on its own. I have never used a telescope before either. is there anything obvious that I should do? Thanks

First you have what we call a department store telescope. It is 60mm, not much bigger than a pair of 10x50mm binoculars. Do NOT use the 2xbarlow if you have one, Put the eyepiece with the largest number written on it into the telescope and go outside during the day time and practice focusing on a distant object.

You probably will not find a manual-- however Meade telescopes maintains a web site for their scopes. Look under REFRACTOR on this page for one similar to your telescope. They all work the same way:
