Hello everyone, I have recently received a National Geographic 76/700 premium telescope. The quality of all the parts is satisfactory, however there were no instructions. I have assembled it to the best of my ability and all the parts fit together and were used, matching the image on the box perfectly (after much perseverance) however when I look through any of the lenses nothing is visible at all. The dust caps have been removed and yet there is nothing visible. If anyone knows where I may have gone wrong or anything I could do to ensure that my new telescope will work correctly, I would appreciate any help.
