I just got my argonavis today and I cant live without it
I have previously used a palm based dsc, but found that accuracy varied a lot depending what part of the sky I was looking at. I could only align on the planets and a pre-defined list of stars. Those stars were not always conveniently placed for a good alignment.
With the argo you can align on any object in the catalogues, so even if accuracy goes out you can just re align on an object close to the wanted target and carry on
