One question: Is the hole going to be wide enought to be usable? Based on the scale of the circles, there are a lot of positions that all you will see through the hole is a bunch of lines with no numbers to tell where you really are. Maybe numbers every 5 degrees instead of every 10 would help this.

Let me know if this is a problem when you test it out.

I was wondering that too, but I'm glad I kept looking for the 3 in. version as opposed to the 2 incher's I had been seeing. Numbers every 5 would be better, but in practice it was very easy to use. The program I downloaded from the beggining of this thread only had the markings as shown and it does spread out a bit when enlarged.
Last night I got a chance to use it, as I was invited to an outreach program at an elementry school for 4th graders. Tom (square-peg) hosted it along with the Maple Valley Astro (MVAS) club. After setting up and leveling the scope (9:00pm) it was still very light out and the only thing visible was Venus. So I decided to start with that one. I looked up the Alt\Az numbers on Starrynight and set the ring\az to the correct number. Saturn was not visible because of it being still bright and the thin marine layer of clouds in the sky. I looked up the position for Saturn on the lap top and moved the scope to those readings...there it was, in the EP (I was using the 12mm Speers WALER at 127x !!! I would have liked to use it more but there was one HUGE problem, (not really )...over 175 people showed up for the out reach! The line at my scope was 30 people deep, all night, just to see Saturn and Venus.
I will try to view again with my wife tonight in a more controlled enviroment and report my findings. Overall I couldn't be happier with the way it turned out and how easy it is to use.
