Dave, I'm happy with the 6 minute divisions on the vernier, considering the FOV on my 18mm eyepiece, it gives me very good accuracy, and it's the default when using Rob Willett's website to generate the circles and verniers. I don't think going to 5 minute divisions would make that much of a difference would it? I'm just happy to be able to see an object first time every time! I haven't turned on the Rigel Quickfinder since the circles went on!. The night before last I 'dialled up' NGC 2239, put the NPB filter (bought on IIS) on my 40mm eyepiece, and hey presto there's the Rosette Nebula! I'm now planning an evening to view a few more objects that will be visible with the filter, and easily located using the circles.
The Bartels board is the prepopulated version, I'll PM you with a picture when I get home from work.
Cheers
Chris
