Cannot see anything
Can you see any ships?
Seriously, if you look at a dim light is it really dark? Is there a cover on the eyepiece?
How to adjust the finder scope
Mount the finder securely on the main scope tube, and make sure each of its adjusting screws is at about mid-travel (BTW a lot of finder scopes have a rubber ring fitted between the finder and its mounting tube. If this is missing a rubber band is a good substitute).
Place a low power EyePiece in the scope (this will be the longest focal length EP you have), and then in daylight, find a distant object like a tower or distinctive treetop. Swing the scope and center this object in the EP (it will be upside down in a standard EP). Then center it in the crosshairs of the finder.
Change to a lower focal length EP (more powerful) and repeat this procedure . Then at night, swing the scope to an obvious target like a planet or a bright star, and repeat the procedure until everything is centered. If you handle and store the scope carefully between observing sessions there will not be much correction needed next time.
