When I use other atlases (typically 9 mag atlases such as Uranometria or Herald-Bobroff), I frequently miss some more faint stars to locate exactly the object. This is the reason to go beyond this limit in the B-atlas. I was using it last saturday night to spot galaxies in the Coma-Leo-Virgo area. I was looking for 12.5 to 13.5 mag objects with my 150 mm refractor (the night was good but far from exceptional), and in all cases, even for quite threshold targets, the atlas gave me enough reference points to locate them very easily. I was really satisfied with the performance: it was better than I originally thought. My initial idea was completing the hard searches with the 5800 minimaps (as I usually do), but with the new atlas was not necessary, except in one instance, just to confirm it. So the success percentage as "standard-alone" atlas was really good. The only point is to get a printer able to reproduce the charts with the same accuracy I have got in the direct printouts. In a 600 dpi laser printer the charts are excellent. Larger resolution gives perhaps too thin stars. I have also generated some proof color maps with a laser color printer. Color maps are even nicer (overlapping is less problematic), have a look to this: chart B-23 in color (proof color combination) ...although obviously I am planning a B/W set. IMPORTANT - I have replaced the A-charts with a new set with a 5º grid (instead of 1º grid) and smaller stars. The first set was too crowded and the charts are now more readable. Have look and tell me the impressions. I hope you will like it. At least I think that now is closer to how I like. Up to the moment, the changes to implement seem to be more clear (outer?) adjacent chart indicators and font sizes.
