Have just realised that you have one of the mini-finders. The vixen rail/guide rings might be a bit of overkill. You might be able with a bit of tinkering, to add another finderscope bracket to the side opposite the optical finder....
Andrews sell extra brackets for $9.00
Or you could
upgrade your focuser to a moonlite and I think they come with an option for finder brackets on both sides...!
