HAC Vice-President Glen Sanner demonstrated his advanced astronomical skills by observing 120 galaxy clusters and galaxy groups. Of the 250 objects listed in the Galaxy Groups and Clusters Guide, one must observe 120 objects: 1) 30 Galaxy Trios; 2) 30 Hickson compact galaxy groups; 3) 30 Additional Galaxy Groups; and 4) 30 Abell galaxy clusters.
Dave Healy, our AL Correspondent (ALCor), said about the Astronomical League’s thirty different observing programs, “I think it’s a very good way to learn the sky. I think we all face the problem of what to look at when we take our telescope out. This is an organized way of learning the sky, and learning very different objects. The difficulty level is from simple to challenging, and the range of optical instruments is from your eye to a large telescope. There are very simple programs where you just identify and map the constellations by eye, and going up all the way to some very difficult ones, including one I am going to award tonight.”
This was Glen’s first observing certificate, but he went right to the advanced level: the Astronomical League's Galaxy Groups and Clusters Observing Club. Dave Healy continued, “This is probably the most difficult club in the entire bunch: 120 Galaxy Clusters and Galaxy Groups. I want to read you the letter he got from Dereth Murray of the Astronomical League: ‘Dear Glen, Congratulations on your achievement on observing and recording all 120 of the objects required for certification for completion of the Astronomical League’s Galaxy Groups and Clusters Observing Program. This certification committee has reviewed your documentation and determined that you qualify for the certificate of completion and special “ GGC Observer” pin (see image, below). You join an elite group of advanced observers and can include this award in your quest for the title of Master Observer.’”
“We have three Master Observers in the Huachuca Astronomy Club,” said Dave, “which I think speaks well for the dark skies and the dedication of the people involved. If you get ten observing certificates: five electives and five required, you qualify automatically for the Master Observer award, and there are three of us in the club.”
“Going back to Glen [the letter], ‘you are hereby awarded Certificate #20 and have been added to the awards Web page, and will be in the ALReflector publication on the awards page. I want to thank you for the quality of your documentation and the effort you put forth to qualify for this award. Kudos for a job well done. Best regards, Dereth Murray, Certificate Committee Galaxy Groups and Clusters.’”

Glen Sanner received the award from Dave Healy and then said, “As you can imagine, this is a fun thing to do. It took me forever. It’s been almost five years that I worked on that. Now, that’s my own fault.”
“So in only forty-five more years you’ll qualify for Master Observer,” said Dave.
“That’s right,” replied Glen, “I want to stretch this out. But you can do this much quicker than that. It took me a long time because I would work on it a while and then put it aside for a while. […] I would encourage everyone to pursue some of these programs. They are a lot of fun, and you will get a lot out of it.”
HAC President Wayne Johnson said, “I have to second that, too. Congratulations, Glen, that’s great, and you’ll notice he’s only the twentieth person to get that award, so that’s out of the entire United States. That’s pretty darn good! But if you’re one of those people who have wondered, what should I look at in the sky, or where should I begin, these Astronomical League observing certificates are a real good way to get started. So, thank you, Dave, for coordinating that, I know Dave has as much fun giving the awards out as anybody. So, we really appreciate it.”
“The duties of the ALCor are very light and very pleasant,” said Dave.
“Dave is one of our Master Observers,” said Wayne, “so that is a great honor.”
Dave replied, “The other two are James Taylor and Bob Kepple, so that’s the three Master Observers in our club.”
Congratulations, Glen Sanner, on your not-merely-stellar, but galactic achievement!
Astronomical League Observing Clubs
The Astronomical League (AL) provides many different observing programs (clubs). These programs are designed to provide a direction for your observations and to provide a goal. The programs have certificates and pins to recognize the observers’ accomplishments and for demonstrating their observing skills with a variety of instruments and objects.

Searching for Faint Planetary Nebulae

What's in your wafer? [Click on image for larger version.]
Photo © 2009 Del Gordon.
What’s on the wafer (pictured above) is a special kind of charge-coupled device (CCD) chip that Dr. George Jacoby and his
team at Kitt Peak invented for the WIYN telescope. The WIYN telescope has
spectacular image quality for a ground-based telescope—yielding images of a quarter-arcsecond resolution. Typically
they can achieve 0.7 arcseconds. Most telescopes on Kitt Peak are one to one-and-a-half arcseconds. This capability allows
astronomers to observe faint planetary nebulae—glowing shells of gas ejected by dying, low-mass stars.
The scientific value of an image is the inverse square of the size of the seeing. So if one is getting half-arcsecond
images, then that’s four times as useful as a one-arcsecond image from the same telescope. The
WIYN team has developed a kind of CCD that actually improves the seeing by following the motion of the stars during the time
the picture is being taken. It does this by moving the electrons around that are being collected so that they always fall
under the stars. If the star moves, the electrons move with it. The next photon creates an electron where this electron
packet has been moved to.

“An Amateur/Pro Search for Faint Planetary Nebulae”
Speaker: Dr. George Jacoby
Synopsis: Theoretical predictions, and some
observational data suggest that our Galaxy is populated by at least 25,000 and possibly 125,000 planetary
nebulae. But, we have only been able to identify 3,000. Where are the rest? Are they out there, and if so,
why are they so hard to find? If they aren't out there, what changes in our thinking about the physics of
stars are required? I will describe a highly international project initiated by seven amateur astronomers
in four countries, plus four professional astronomers in three countries, to search for additional
planetary nebulae using existing data from on-line digital surveys. The amateurs provide a list of
candidates, and the professionals direct their more capable telescopes at the targets to obtain detailed
images and spectra to classify the candidates precisely, either as planetary nebulae, supernova remnants,
galaxies, HII regions, etc. Thus far, we have obtained images for 76 of the initial 97 candidates using
the WIYN 3.5-m telescope on Kitt Peak. Of these, 15 objects were rejected based on their appearance. Of
the remaining 61, spectra were obtained for 31 and 5 of these appear to be supernova remnants while the
remaining 26 are newly discovered planetaries.

Welcome to the Exciting World of Astronomy
The featured speaker for the January 2009 HAC meeting was Bob Gent, and his topic was entitled, "Welcome to the Exciting World of Astronomy."
The program included selected astronomical images from spacecraft, some from professional observatories, and others from amateur astronomers. In addition, Bob showed some of his favorite reference materials that he used to get started in astronomy. He will conclude his talk with a brief discussion of the urgent need to protect the beauty of our night skies.

The Chandra Deep Field South Image
Scott Schneeweis presented the Chandra Deep Field South image, from the European Southern Observatory (ESO). The image
represents a 40-hour stare, observed in the U-, B-, and R-bands. The U-band VIsible MultiObject Spectrograph (VIMOS)
observations were made over a period of 40 hours and constitute the deepest image ever taken from the ground in the
U-band. The image covers a spot in the sky 14 x 21 arc minutes—a third of a degree—which is about one-third
the size of your finger held at arm’s length. What you see are tens of thousands of galaxies. There are even
merging galaxies that appear to be doing the tango. The deeply red-shifted objects are probably about 11.5 billion
light years, so that’s about 85 or 90 percent of the age of the known universe.

Did you know?
As of July 2009, the Large Binocular
Telescope (LBT) on Mount Graham, Arizona,
is the world's largest optical telescope. The LBT has taken celestial images using its
twin side-by-side, 8.4-meter (27.6-foot) primary mirrors together, achieving
first "binocular" light. The LBT has a light-collecting area equivalent to a
single 11.7-meter (39-foot, or 464.5-inch) surface and will combine light to produce the image
sharpness equivalent to a single 22.8-meter (75-foot) telescope (900 inches). It is located on
3194-meter (10,480-foot) Mount Graham in southeastern Arizona.
U.S., Italian and German partners in the LBT, have released new images. First
binocular light is a milestone not only for the LBT—now the world's most
powerful telescope —but for astronomy itself.
The world's largest segmented telescope is
the Gran Telescopio
Canarias (meaning "Great Canaries Telescope"), also known as GranTeCan or GTC. It is a 10.4-meter (410-inch) reflecting telescope undertaking commissioning observations at the Roque de los
Muchachos Observatory on the island of La Palma, in the Canary Islands of Spain, as of July 2009.
"Amateur astronomers today are exceptionally fortunate to be living in an era when high quality,
and very large, optics are so affordable."

That's Cool Wire

That's Cool Wire
Due to many requests, here is a link to the web site that sells the electroluminescent wire: thatscoolwire.com
Some pictures can be found here. 
Specifically, the product similar to that you may have seen at HAC events can be found by clicking here.
The above link is the medium width wire. For wrapping around telescope tripods, the thinnest wire may work best, as it may be slightly dimmer.
For comparison, the model number purchased was: WY-PPL-N2, (2.2mm), EL Wire Kit 4, 15 feet, 3VDC, $17.61. This model was used to wrap around the handle of a step-stool for visibility.
Longer lengths, such as 26 feet, might be better for other applications, such as tables or signs. Measure for your application and order accordingly. The wire can be powered by two AA batteries, or with an AC adapter.

What is the Temperature of Deep Space?
Glenn Minuth gave a follow-up report to his prior talk in April on “Earth’s Energy Balance.” James Taylor had asked about why his infrared thermometer read -127° C when he pointed it into space. This leads to the question, “What is the temperature of Deep Space?” This is like asking, “What is the temperature of Earth?” How would you describe the temperature of Earth, would you use a range, or an average, or would it depend on your particular location? It turns out that as a result of the Big Bang, we can observe what is known as the Cosmic Background Radiation. Wherever you go in the Universe, if you are not close to a planet, that is, that temperature turns out to be 2.7° K (-455° F, or -270° C). If you are in the area of our solar system’s outer planets, the temperature is around 40° K (-388° F, or -233° C), and increasingly warmer the nearer to the Sun that you get. The temperature of absolute zero is 0° K, and nothing that we know of can get any colder than that, because at that temperature all molecular activity stops.
