Star Party Presentation Cheat Sheet - Older Low-Metallicity Globular Clusters for Aug Sept

This is to announce a star party presentation cheat sheet for use at
astronomy club star parties.

http://members.csolutions.net/fisher...rtyAugGlC.html

Using a GOTO mount in a series of quick slews around Cygnus, show
three of five older low-metallicity globular clusters and one younger
high-metallicity globular cluster by increasing distance and compare
their relative visual angular and physical sizes. Explain the high
concentration of low-metallicity RR Lyra variables in these clusters.
The cheat sheet includes an observing list, a table of physical
parameters, finder charts, images, background information and
suggested discussion topics.
