I suppose that there is some distortion getting a flat chart onto a spherical surface, but it shouldn't be too much trouble. If you drew the RA and Dec lines onto the sphere, and then eyeballed the stars into their respective sectors for a drilling pattern, you should come out pretty close. Maybe someone else can jump in here with some better suggestions. Hi Ken, You may not be around but to whomever stumbles on this thread, here is the chart Ken asked about www.suopte.com/en/apps/stellasphaera.phpThe creator Bende Agg was kind enough to expand the RA rings to 48, the Dec rings to 36 and put lables on star magnitudes for me. Not every last one but if the star has a name it uas a magnitude lable. You just have to import the PDF into a decent photo editing program and scale it for whatever sphere size you are using.

Hi again I am still around, but not quite as active on this group. Thanks for the post. That is really interesting stuff. Ken
