Starship Asterisk*

I notice multiple horizontal lines in this image. I am new to astrophotography and every time I photograph the Great Nebula I end up with horizontal lines that I can't explain. Is this the busiest part of the sky for us? Can anyone help explain? Thank you.

Hello??? I was trying to find a message board or thread or something where people introduce themselves. Surely this isn't the one...with only three posts? Hello though!
