"Alien Vision Revolution." "I
will describe research that has led to a new
understanding of the function of color, binocular
vision, illusions and the shapes of writing over history.
By understanding the design principles underlying
these visual phenomena, we have a basis for
speculating on how aliens are likely to see. In
particular, I will argue that aliens will perceive the
same kinds of illusions and have writing that looks like
those found here on Earth, but that they will not have
our variety of primate color vision, nor have our

"Clusters of Galaxies: Life in Galactic Cities"
Clusters of galaxies are the most massive structures in the Universe. They can contain thousands of galaxies, large amounts of hot X-ray emitting gas, and even more dark matter. I will review our current understanding of how clusters form, and I will highlight some of the remaining mysteries yet to be solved. In particular, my area of research explores if and how the cluster environment affects the evolution of member galaxies.

Dr. John Delano
"Astrobiology: The search for life beyond the Earth"
We are very pleased to have Dr. John Delano as our speaker once again. Dr. Delano's talk will be "Astrobiology: The search for life beyond the Earth."
"Questions in astrobiology are being explored by teams of scientists in astrophysics, biochemistry, geochemistry, and geophysics. How common are habitable planets? How are complex biomolecules formed on initially lifeless planets? What processes and environments are required for planets to become habitable? What instruments are needed by robotic spacecraft to detect either living or fossilized microbial life? These are some of the fundamental questions where substantial progress is being made. In addition to results from NASA's Kepler spacecraft that are anxiously awaited bearing on the presence of Earth-sized planets orbiting other stars, these are exciting times!

"A Few of My Favorite Things"
Long-time amateur astronomers collect a wealth of favorite sites over the years. These celestial wonders may be treasured for their beauty, for their nature, or even the circumstances under which they were seen. Sue will share some of her most memorable deep-sky observations, garnered over the last three decades. Sue is an avid deep sky observer and a Contributing Editor for Sky & Telescope, writing their monthly "Deep Sky Wonders" column.

Various club members
Our February "Member Potpourri" went very well and was well received, so
we're going to do another for the July 20 meeting. Perhaps you have
something to share with the club - a review of a book or an accessory,
some favorite targets in the night sky, a memorable telescope or night
of observing, or a trip or convention report. Maybe you have some
insight into a specific aspect of astronomy or some news in the world of
astronomy other club members would enjoy hearing about.
Please let me know if you have something to share at the July meeting.
(Please include an estimate of the time required.) We are looking for
several talks that take from five to fifteen minutes.

Meeting and Star Party at Landis Arboretum
Our August meeting is held in the Meeting House field at Landis Arboretum. Weather permitting, there will be a star party after the meeting. We generally socialize and check out everyone's telescopes if the weather is nice. If the weather is poor we do a variety of short topics in the Meeting House. You are also welcome to bring items for the "August Swap Shop."
Tuesday, September 21, 7:30 pm at the Schenectady Museum
Dr. Harry Ringermacher speaking on
"The State of the Universe."
The universe continues to amaze and provoke. You see recent discoveries in every popular venue. Black holes in the center of every galaxy, "dark matter", "dark energy" everywhere and we don't know what it is except it's 96% of the stuff out there and we're the dregs. Extra dimensions and multiple universes. Science fiction, reality? You will get the latest scoop along with pretty Hubble images and the latest incredible super-computer simulations.

Our October Meeting, by Alan French
The second of Dudley Observatory's Skywatch Lectures, Alex Filippenko's talk "Dark Energy and the Runaway Universe," coincides with our October 19 meeting. Although we try to avoid moving our meeting, this marvelous opportunity is far too good to pass up. We will not be holding our regular meeting at the Schenectady Museum, but will be meeting in conjunction with the Skywatch Lecture at the GE Theater at Proctor's.
The Skywatch Lecture begins at 7:30 pm. Tickets are $11 for general admission, $8 for members of Dudley Observatory, and $6 for students. We strongly urge you to support the Skywatch Lecture series by purchasing tickets, although we will have a limited number of complimentary tickets available for AAAA members. Your support, through the purchase of tickets, will help insure the success of this year's Skywatch Lectures and its continuation in years to come. If you do require a complimentary ticket, and your dues are up to date, see me before 7:20 pm outside the entrance to the GE Theater.
Dr. Filippenko is a Professor of Astronomy at the University of California at Berkeley. He has produced four astronomy courses for The Teaching Company and is the coauthor, with Jay Pasachoff, of an award winning textbook, "Cosmos: Astronomy in the New Millennium." He is the Richard and Rhoda Goldman Distinguished Professor in the Physical Sciences and has won several major awards for his research. He has also received top teaching awards and has been voted "Best Professor" on campus six times. I hope you will join me, and support the Skywatch lectures, at this exciting program!

Sue French, author of Sky & Telescope's "Deep Sky Wonders" column
"Winter Sky Wonders"
"For many of us, this is the coldest time of the year - but it also harbors the most brilliant stars and some of the most spectacular wonders of the deep-sky. They include nebulae, clouds of gas and dust either glowing by their own light or reflecting the light of nearby stars; clusters of stars, both old and young; galaxies far beyond our own Milky Way; multiple stars of surprising beauty; and variable stars that challenge our notion of a constant sky. And if that's not enough, we also have intricate Jupiter in our evening sky and awe-inspiring Saturn in the morning! We will tour the brightest and best telescopic delights of the winter sky, and each object will be paired with a nearby but less-known wonder to tempt the observer with more experience."

"Rediscovering the Telescope"
Debates about telescopes are popular on the Internet and on cloudy nights at conventions. The pros and cons of various designs and features get debated endlessly and minor points generate lengthy discussions. Manufacturers tout the advantages of their products and emphasize the disadvantages of their competition. In the end, the amateur often winds up with a distorted view of telescopes, and selecting a telescope becomes more confusing than necessary.
We'll rediscover the telescope, uncovering what is really important in how they perform under the night sky. The program will also provide a simple, non-mathematical explanation of what determines whether a refractor is an achromat, with some visible out of focus color, or an apochromat, with no obvious out of focus color.
Alan's talk is sponsored by Flurry Astro Innovations.

Tom Field will host a Webinar on spectroscopy for amateur astronomers.
Spectroscopy is the art of analyzing the colorful rainbow spectrum that a device like a prism produces. Spectroscopy is the primary research tool used in modern astronomical research. However, until the last few years, spectroscopy has been too expensive and difficult for all but a few amateurs. Today, though, new tools make spectroscopy accessible to almost all of us. You no longer need a PhD, dark skies, long exposures, or enormous aperture! With your current telescope and camera (or even a simple web cam) you can now easily capture exciting spectra, including the atmosphere on Uranus or the red shift a quasar. This talk, with lots of interesting examples, will show you what it's all about, and how you can get started.

"A Tour of Our Solar System," by Alan French.
"Things have changed greatly since I devoured my 1958 copy of Roy A. Gallant's Exploring the Planets. My tour will feature some of the finest photographs of our solar system, and contrast what we know now with the state of our knowledge in 1958. We've come a long way in a bit more than a half century, mostly because of spacecraft and other new tools for exploration."

Harvey Patashnick, "CCD Imaging in Astronomy...The Fusion of Science and Art."
The pursuit of astronomy for both pleasure and science no longer requires access to mountain top observatories and dark sky sites. With the advance of modern electronic cameras and software, spectacular images of stars, galaxies, nebulae and planets is now possible even for "backyard" astronomy enthusiasts at sea level urban locations.As a consequence, the division between amateur and professional astronomy has narrowed.Images obtained even by modest amateur-sized telescopes can be used for scientific data or artistically pleasing images of a spectacular universe.
In this talk, Harvey will present an explanation of the equipment and techniques he has used and the results obtained from a backyard observatory that he has constructed.Along with many images he has obtained over the past few years, he will describe the astronomy research that he guided through the mentoring of two high school students, both of whom became Intel Science Competition finalists as a result.

"Aphrodite's Shadow, (The June 5 Venus Transit and How to Observe it Safely)" by Alan French
When Venus catches up with our Earth and passes between us and the Sun, the planet usually passes above or below the Sun. At intervals of more than 100 years, Venus passes in front of, or transits, the Sun twice, with the transit pair separated by 8 years. The last transit was on June 8, 2004, and the next is visible here on June 5 of this year. The last transit was in progress as the Sun rose. This transit will start just after 6:00 pm, and will still be in progress as the Sun sets.
Observing the Sun without proper equipment is dangerous and can quickly cause permanent, irreversible eye damage. The talk will include ways to safely observe this rare event.
The next transit of Venus will not be in our lifetime. The next pair occurs on December 11, 2117, and December 8, 2125.

"Astrolabes," by Sam Salem.
Astrolabe projection principles date back more than 2000 years ago. The astrolabe has been known as the medieval astronomical instrument capable of measuring the altitude of the sun and stars or a star. The astrolabe has been viewed as an observational device, an astronomical computer, a model of the heavens, a timekeeping device, and an educational tool.
The astrolabe is an interesting example of how different cultures have contributed to the progress of astronomy by adding new applications to the device to serve certain needs. The Arabs modified the Greek astrolabe to be able to calculate the prayer times by detecting the motion of the sun. The Europeans used the astrolabe as a nautical device to tell the time and measure the altitude. The astrolabe evolved to be a sort of analog computer with hundreds of uses. The craftsmanship of the astrolabes in the medieval time was a representation of the art and culture at that time. Then, astrolabe was a piece of art and a symbol of prestige for its owner.
The talk gives an overview of the history and applications of this beautiful astronomical instrument
Thursday, August 16, 2012 at 7:30 pm Landis Arboretum in Esperance
Every August we meet at Landis Arboretum instead of the Schenectady Museum. There is no formal program, it is a chance for members and guests to socialize. Club members set up telescopes for a star party that starts after darkness falls, so the meeting is good chance to see a variety of instruments and get some views of celestial sights (weather permitting). The club will also hold its Second Annual Ice Cream Social," so skip dessert.

"NASA's Search for Life Beyond the Earth," by Dr. John Delano
The number of planets, confirmed and unconfirmed, orbiting nearby stars is approaching 3,000. Among these exoplanets a few may have conditions that would be suitable for life as we know it, but there are still large uncertainties with any claims for habitability. Dr. Delano will discuss some of the latest results bearing on the geochemistry and astrophysics of life's origins.
We are very pleased to have Dr. Delano return as a speaker. He has spoken to the club many times over the past two decades, and has been one of our most popular guests. Please join us for this exciting program.
