I'm considering getting a set of Argo Navis digital setting circles for my 18" dob. I like to think I'm quite good at finding stuff using just my charts and Telrad but, sometimes, it gets to be a drag and I wish I had something like Argo Navis. I've seen these in action at the Texas Star Party and at home in England, too, and they look fantastic.
How easy would they be to retrofit to my 18"? It's made by UK scope maker David Lukehurst and is based on the Obsession design.
Cheers
