Slides

Thirty-one 35mm slides are included in the HOA materials. These slides may be used with the lessons in the manual to help illustrate the changing brightness of variable stars. The slides include:

• Finder slides of each of the five constellations included in HOA.
• Multiple views of each of the constellations.
• Seven views of the Cygnus constellation in its entirety. These views are the same as in the Cygnus constellation prints and show several variable stars in different stages of variation.
• Seven views of the field of the variable star W Cygni. These views are the same as the W Cyg prints and follow the variable through most of its cycle of brightness variation.

Below is the major finder slide of the constellation Cygnus. It outlines the stars in the constellation and identifies them. This is the first step in locating a star. Using these guideposts students can look for the individual stars which interest them. Select the image for a close-up view.
