The most likely cause of the problem is that your finderscope is not aligned with the main optics. To align your finderscope, take your scope outside in the daylight and find an object at least a half mile away as far away as possible (a street sign, telephone pole, radio tower, mountain top, etc.). Center this object in your main telescope using your lowest power eyepiece. Now look through your finderscope. Using the three adjustment screws that secure the finderscope into its bracket, tighten or loosen them as needed to bring the cross hairs onto the same target as is centered in your main telescope. Your scope is now ready to be aimed at any object in the sky and it will easily be located through the main optics of your scope.
