Help needed please, I am new to stargazing and have just bought a used celestron 130 telescope. The first day of setting it up i accidently dropped it and the mirror at the back came loose. I have managed to place it back but i think it is not lined up properly. I managed to see jupiter last night but had a view like a big spider. If anyone can help i would e most thankful. I am a complete novice so not to sure what I'm doing
