Hi Carl,
The SN 10 is a fine scope, as commented by others below.
I have the same ota and did a refurb on it not that long ago, including adding a moonlite focuser, a new finder scope foot, internal flocking and a general clean. The thread is here

I have it tested under the stars and it's a great performer, though you do see dimming from the central obstruction if you use long eye relief eps and you move your eyes out from the EP.
I am trying to do some AP work on it but weather has been terrible, Peter from the above thread link has done some AP work and I think he is quite happy with the results.
Keep an eye out for in the trades for any good second hand focusers.
Good luck!
Bo
