Well, maybe. That sounds about right now that you say it. If I wasn't new I might know the lanquage. That's why I described the function I needed and asked what it was called. It ain't easy being green. Fitting a CGEM tripod would be nice and I'd hoped would save me some money but could also make the whole search harder. I take it that the CGEM dove tail mount is a standard then ? Maybe I should have posted this in the begginers forum.
