I picked up a used Vixen GP mount yesterday from a gentleman who had inherited it but was not interested in astronomy. As such, he was unfamiliar with most of the equipment. He handed me this before I left and said he was not sure what it was but thinks it was for the mount or scope.

I looked through all the manuals for the scope and the mount but nothing like it is mentioned. It does attach to the bottom of the mount where it attaches to the tripod but then there is no way to attach it to the tripod with it on. My best guess is that it’s a cover for transport to protect the bottom of the mount. But it’s really heavy/\solid so it makes me wonder if it’s for something else.

Any help would be greatly appreciated!
