With the Meade LX70 mount, I also purchased the Polar Alignment Scope. Again, I had to download the instructions off of the Meade website. It was easy to remove the existing item and screw the polar alignment scope in.
However, I was confused when I looked through it. I couldn’t see anything. I looked at the other end and it seemed to be blocked. But, there wasn’t anything in the manual and thought I was just missing something. But, then I turned a part of the mount and it was revealed the piece inside had a different shape. Problem solved.
The next step is to align with the mount but that will be for another time.
