Edz,
What do you do with the stars that straddle the border of your chart?
Last night I counted 43 in my 15x70's and 34 in both my Pentax 8x40 and OB Mariner 7x50. Skies were 5.6 based on the Polaris LM chart. This is much lower than your count (on the same instrument in one case) under lessor skies. There are stars that I think I see pop in but then I can never quite see them again, even averted, so it's hard to count. But it's fun trying. I'm getting the hang of the borders of your chart.
Also, what is the source of boundaries of clusters like this?
