Hello, 
I’m a 55 years old man who just discovered the passionate, and difficult hobby called astrophotography. I got some images but I still need tones of experiences. I can’t even call myself an amateur yet. I leave in a small city called Aberdeen in Maryland, and I believe that I will be the only person in my city to have engaged itself in this “madness”. 
Then you can imagine that I will rely a lot on this website to get most of my unanswered questions from most experienced persons. 

I got already one. My EQ6 mount is making a strange taping and regular noice like: Toc, toc, toc ,toc ,  after meridian flip, and stop tracking. Can anyone explain me what is going on? I tried everything to no avail. Thank you for your help.
