I'm in the boonies for all intents and purposes. Can someone please tell me the size of bolt to mount a plate to the flat top part of the rings on my refractor? I'm guessing it may be metric, but before I order anything I'd like to know for certain. Thanks. Rick

I checked 1/4-20 but it's smaller so I'm thinking it's probably M6 but I don't have that size bolt to check.
