Thad, I've got two different printouts of M57 with calibration stars, one has
black stars on white background and came from
http://c3po.cochise.cc.az.us/astro/images/M57!dss2_3.jpg The other has white
stars on black background and works better when at
the telescope trying to find the central star or just calibrate what you can
see. Unfortunately I don't know where the second one came from but, if you
can't find one like it, I'll be glad to make a copy for you.
We deserve clear skies!!!
