Can anyone tell me about Argo Navis.

It sounds like it might suit my purposes, but the web site is less than forth coming about details of operation.

Here is what we have and what I am after:

Wife and I have 2 scopes, an 8 inch Kat, and a smaller Newtonian, both on motor driven polar mounts.

We would like to share an attachment that nominates the star / system that we have the telescope pointed at.
This is for conformational purposes, - Brisvegas has skies that are so light-drenched that it is sometimes very hard to use “dead reckoning” style navigation, and we are often not sure what we have found, especially if Stellarium is showing several formations in the same area.
(I don’t want Go-to navigation control, as I think they tend to minimise the learning process for newbies.)

So: does A-N provide what I think it does, and can it easily be swapped from scope to scope, or are there bits that aren’t shown in the web site: (photo shows unit plus mounting cage)

Secondly, does it have USB connections for upgrades, as my laptop doesn’t have the antique connection systems used by some skybound devices?

Any help appreciated.
Regards Rider.
