1 Volume 51, No. 6 September, 2006 (OUR 50 TH YEAR) FROM THE EDITOR Marc Hutton Welcome Back : September 19th "What I Did During the Summer Break" All "Whats Up": - Greg Lee Welcome back from our summer break. Hopefully everyone had an enjoyable summer that included some time to enjoy the wonders of the summer night sky. This month is our annual "What I did during the Summer Break" program. In order for this to be successful we need for you to bring in and share your photos and stories of your summer adventures. While it would be nice, of course, if there was some relevance to an astronomical theme, it is not one hundred percent necessary. So dig out those pictures and we will see you at the meeting. PRESIDENT S MESSAGE Hank Bouchele I am boundlessly optimistic that this will be a good year for the Delaware Astronomical Society. There is much to do and much to celebrate. It is my great honor to be its president. I personally cannot imagine a greater vote of confidence. And it matters that this is our Fiftieth Anniversary. I ran for president promising changes, but this is an organization with a long history. It is the nature of all things to change, and yet to remain the same. Change brings the opportunity for advancement, improvement, and breaking out of whatever constraints we have created for ourselves. Things stay the same in the ways that we bind ourselves to traditions, and the ways that we value the past that brings us together. We begin our first meeting of the new season with what has become a tradition for the DAS, a program composed of the contributions of its member as they share their activities since last we met in the spring. Come join us! To make it easy to share, Max Peterson has offered to be our audiovisual guru. If you need any help to make sure your slide or digital presentation goes off without a hitch, you can call him at , or reach him by atobstacle02@gmail.com. 1 DAS Member Among Top Finishers for National Service Award. - Marc Hutton One of the Delaware Astronomical Society's most active youth members, Max Peterson, was recently announced as being among the top four finalists for the Astronomy League's 2006 Jack Horkheimer Award for Exceptional Service by a Young Astronomer. The Jack Horkheimer Award recognizes exceptional service by Astronomy League astronomers under the age of 19. The award is based upon service directly to the Astronomical League, or to any of the Astronomical League's member societies. This service can be in many different forms ranging from public educational outreach, knowledge and skills at public star parties, or other astronomical service. The award is sponsored by Mr. Jack Horkheimer who is better known by many as "The Star Gazer" of the show by the same title which is aired on many PBS stations nationwide and can also be found on the World Wide Web. According to Max's mother, Julia Dooley who is shown with him in the photo accompanying this story, Max learned that he had finished as fourth runner-up for the award in a letter from the president of the Astronomical League Bob Gent. The letter stated that Max had been selected based on his outstanding accomplishments and that they plan to publish an article

2 take this opportunity to introduce the Board members to the membership, though most of them are known to you in some capacity. about him in an upcoming issue of the Astronomical League's quarterly magazine, Reflector. In fact, that has already occurred in the September issue. Max also received a one year gift membership in the International Dark-Sky Association as part of the honor. President: Hank Bouchelle For most of the time that I have been a member of the Society I have run the Colonial School District s planetarium. My particular interest is observational astronomy, and the way that direct observation can advance an understanding of astronomical concepts, whether on the part of the K-12 students I serve in my district, or the University of Delaware students that I teach in the evenings. I also have a keen interest in antique clocks, and for some years had a clock shop. I live in Welshire, north Wilmington. IOTA TO MEET AT MT. CUBA - Greg Lee The International Occultation Timing Association (IOTA) will hold its annual meeting at Mt. Cuba this year on Saturday and Sunday, Sept 30 - Oct 1. In addition to the meeting there will be an excellent local observing opportunity on the following Monday evening Oct 2nd. The 8.8 mag star SAO will be occulted by the asteroid (25) Phocaea at about 8:52 pm in a north-to-south path that passes almost directly over Mt. Cuba. This is one of the better occultations that will take place during the rest of the year and we are lucky that we might have a chance to see it. Vice-president: John Case John is a professor of computer science at UD., specializing in theoretical computer science. He lives with his charming wife in Bear, DE. His particular interest is in observing the sky, especially with the aid of interesting tools and gadgets. Treasurer: Bob Mentzer Bob is a retired physics teacher in the Colonial School District. He has been a member of the Society and has served as its treasurer for many years. He lives in Bellefonte. Paul Maley, VP of IOTA, has offered to run a training session on Saturday morning for anyone who would like to learn the process of how amateurs can contribute useful data to science by observing and timing occultations of stars by asteroids or the Moon. (You don't have to attend the full meeting). If you're interested in attending the training session on Saturday and/or tagging along with an experienced observer on Monday let Greg Lee know: greglee28@hotmail.com or Secretary: Lynn King Lynn works as a word processor for a major company in Wilmington, and lives in Edgemoor Gardens. She is very active in the Brandywiners and various other groups. Her particular interest is observing, especially with binoculars.

He is leader of the Society s telescope making and astrophotography special interest groups. NEW MEMBERS THIS MONTH -- WELCOME JEAN WILLIS FRANK BELLOMO WILMINGTON DE WILLMINGTON DE DAS Board Introductions- Hank Bouchele Board Member at Large: David Gus Swartout The DAS Board of Directors is composed of its four officers, the Board members elected at large from the membership, and the Chairs of the standing committees. Among the privileges and pleasures accorded the president of the DAS is the opportunity to make appointments of the standing chairs or other vacancies as they arise. The Board is composed of thoughtful, intelligent, and personable individuals, and it is an honor for me to have the opportunity to work with such good people. Gus lives in Bear, DE and is employed by a management company in northern Delaware as a software consultant, for which he travels extensively. He has a 10" Schmidt-Cassegrain on a permanent mount, located in his tomato garden, and an 8" F6 Newtonian with a Dobsonian mount, which is great for observing the planets and the Moon. His particular interest is Messier Objects. Gus spends his summers visiting the beach and sailing small boats. It is my hope that this spring s election will inaugurate an era of increasing communication between the Board and the membership, extending and welcoming the opportunity for members to become more involved in the Society. In that regard, I would like to Emil, retired from the DuPont Company (after 34 years in R&D), has been a faithful servant of the Delaware Astronomical Society, being in on its founding and serving as its third president.

LIBRARY NEWS Glenn Bentley Fall is almost upon us and Orion is being sighted in the east earlier and earlier. I hope everybody had a good summer and enjoyed warm evenings under the stars.

We have a new President and new programs and activities are under development.

4 LIBRARY NEWS Glenn Bentley Fall is almost upon us and Orion is being sighted in the east earlier and earlier. I hope everybody had a good summer and enjoyed warm evenings under the stars. I experienced several evenings of black transparent skies in the Wenatchee Mountains in Washington in early August. The Milky Way was magnificent. This year marks the DAS s fiftieth year. We have a new President and new programs and activities are under development. Just one of the new ideas related to the Library is to convince DAS membership to submit astronomy book reviews, and/or reviews on associated topics for publishing in the Focus. Members are warmly invited to stop by the DAS Library after the next meeting to browse the shelves. LOANER TELESCOPES -- Emil Volcheck Spring's mild weather months will be a good time to get out and try your hand with a scope. So, if you are new to the club and/or do not have a scope, you can get the loan of either: or 1) a Celestron 8" Schmidt-Cassegrain 2) an Orion 6" Dobsonian reflector The loan is for at least a month (depends on how long the waiting list is). To get on that list, promptly, contact Emil Volcheck, or from how to get started with a minimum of equipment, to polar aligning your telescope, all of the way to the fine points of using auto-guiders and post-processing digital images. If you are interested in joining the AP SIG, just your name, address, and phone number to me at hanaganw@comcast.net. SAWIN OBSERVATORY REMINDER -- Tom Sidowski DAS members who are interested in becoming users of the Sawin Observatory and/or the Big Red DOB, should contact me at to arrange for some hands-on training in using the facility. DAS AMATEUR TELESCOPE MAKING SPECIAL INTEREST GROUP (ATM SIG) -- Bill Hanagan The DAS Amateur Telescope Making Special Interest Group meets on evenings and weekends according to the availability of the members and the particular projects that are underway. The general range of activities of the ATM SIG includes all manners of telescope making, mirror making, and the making of accessories for telescopes and observing. Anyone interested in joining us should their name, address, and phone number to me at hanaganw@comcast.net. ASTROPHOTOGRAPH OF THE MONTH - Bill McKibben MCAO PUBLIC NIGHTS Emil Volcheck The Mt. Cuba Observatory Public Nights continue year round! In addition to learning about many aspects of the heavens, you'll have a chance to visit and view our all-digital full-dome planetarium! You can pick up a schedule when you next come to a meeting - or get the latest updated version off the website at: DAS Astrophotography Special Interest Group (AP SIG) Bill Hanagan The DAS Astrophotography Special Interest Group meets on Friday nights at 7:30 PM every other month at Mt. Cuba regardless of weather. The SIG also meets for photo shoots scheduled on 1-2 day notice to synchronize with the weather. The monthly meetings are informal and typically include the presentation of astrophotos taken by the members along with an extended question and answer period. Objects commonly photographed include constellations, auroras, lunar eclipses, and planetary photos, as well as a wide variety of deep-sky objects such as nebulae, galaxies, star clusters, etc. The topics discussed cover the entire gamut of astrophotography, The image of the Trifid Nebula was taken with a Canon 20D (standard) DSLR camera at prime focus through a Vixen ED 80 f/7.5 refractor. The mount was a Celestron CG5 ASGT Mount. The final image was made up of 14 exposures at 120 seconds each at ISO 800. The exposures were stacked in Registax 3.0 and touched up in Photoshop CS2. The image was taken from my back yard in Elkton, MD on an exceptionally transparent night on August 12, This was the first image taken through the Vixen ED 80. I got the scope, in large part, for its wide field of view and I am very happy with the early results. The two minute 4

5 exposures pushed the limits of the mount as I rejected roughly 40% of the raw images. However, if I am able to count on a 60% success rate without guiding, I like the math considering the reasonable price-tag of the mount. Now for some more clear skies! Editors Note:- I am very interested in making this a recurring feature of the Focus, but that is only possible with your help. Please, send in your best efforts along with a brief description of the equipment and conditions, along with any commentary, and share it with the whole club.
