FREE HANDOUTS FOR YOUR EVENT
The link below is for a quick two pager, or you could copy/print it front and back on a single sheet. Has sky chart, key things to see, and more. Assuming you used this, you could hand them out as they arrive. As they walk up to each telescope to look and to learn about what that scope is viewing, you could circle the location or the item they are observing so when they go home they have something to reference and remember.
Perhaps even attach something about a local astronomy club.
I have run small personal star parties. I like to have a hand-out, something they can look at and take with them. This works well.
Got to this link. You will see skymaps for Northern Hemisphere, Equatorial and for Southern Hemisphere. There is a PDF download for the two page handout.

The current one is for March. They will publish one for April.
Just an idea.
