It is very easy to buy a telescope that doesn't work, or that resists your attempts to operate it. When you first see it in the store, it looks terrific. But such telescopes are usually difficult to use, and after you've struggled with them to find the moon, a planet or a bright star, you give up and put it away, or wait until your next yard sale. The first problem with these 'scopes is that the tripod they come on is usually not very sturdy, and the instrument won't stay steady, or can't be properly held on target; the second problem is, the eyepieces are so small it's hard to look through them. If you've got a troublesome telescope like this, my best advice is to use just the eyepiece that gives the LOWEST magnification - between 30 and 70 power, and no more. Firm up the mount by replacing the cheap aluminum nuts and bolts with ones of better quality. Also, line up the finder scope with the view through the main tube’s eyepiece, or you’ll have a hard time finding things up there.
