Look out on any clear night, and see a sky speckled with stars bright, dim,
and if you look carefully, colorful. What causes the gem-like colors in
stars? What makes some stars millions of times brighter than the Sun, and
others so dim as to require large telescopes to detect? How did the Sun come
into being, and what is its ultimate fate? And finally, how did astronomers
answer these questions in the first place? We will cover all these topics and
more in the first part of SFAA's two-part lecture series on the Stars.

Join us for this exciting and informative talk, featuring breathtaking
photographs from SFAA astrophotographers Bert Katzung
(http://www.astronomy-images.com) and Geoffrey Collins, as well as other
amateur astronomers worldwide. Newcomers to astronomy and students are
especially welcome. The concluding lecture, by SFAA board member Steve
Bryson, will be featured at the SFAA August General Meeting.

Michael Portuesi is President of the San Francisco Amateur Astronomers. He
bought a book on the constellations in third grade, and has been entranced by
the sky ever since. The passage of Comet Hyakutake in 1996 inspired him to
build his own 10-inch telescope in John Dobson's telescope making class. An
avid observer, he holds the Astronomical League Messier and Sunspotter
certificates, and is a member of FLOP (the Fraternal Loyal Order of
Plutocrats, those who have found Pluto with their own telescope). He is
currently pursuing several more observing programs. He enjoys sharing the
Universe through his telescopes, public talks, articles, and even TV
appearances. His past SFAA talks have covered the planet Mars, viewing
nebulae, handheld computers for astronomy, and telescopes. See his website at
