For each object discuss significance and how it fits in the structure and scale of the universe (what, where, how far away, how large, how old). Option: have teachers pick an object, research with good resources in room, like Burnham’s Celestial Handbook, astronomy texts, etc, and report to group with a HOU image to support what they research. They can process image and show what they have done, links for it on Internet. etc.

Choose three of the following.
- Drawing of the composite of six images of Jupiter and its moon taken over six hours of time.
- Analysis of the relative speed, direction and brightness of the moons.
- Galaxy Features worksheet with sketches and record of image processes applied, noted galaxy features, and results of analysis and identification. Participants will print and frame or make a button out of their favorite galaxy. Print an image and explain how you would calculate the size of one or more features
- Begin the development of an observing plan.
DAY 3 MEASURING BRIGHTNESS
MORNING
