Hi. I've been given an old Tasco 302012 900mm Reflector but I'm not sure about some of the equatorial mount usage. In the attached picture there is some sort of cam that rotates but I don't know what it's for. Also, the bolt for the altitude adjustment is long on this side but for what purpose? Also, there does not seem to be any fine adjustment for altitude. It's missing a slow-motion cable - can you get these anywhere?

Thanks!
