Hi Glen and Marc, I heroically
manually guided for nearly 50 years, so I've been around the traps, as the saying goes. My current gear is the last I shall use before having to finally give it all up. I don't have an autoguider, or an O.A.G. and don't have enough back focus to use an O.A.G. anyway, so am limited to the mount's tracking capability. When I have good P.A. I can manage 100 sec subs with some longer acceptable ones interspersed among them. I'm happy with that, but just can't get useable Go To as well, just one or the other.
