The Northwest Suburban Astronomers We have moved. You will now be taken to the new NSA Home Page About the Northwest Suburban Astronomers We are a group of amateur astronomers from the Northwest suburbs of Chicago, with a wide range of interests and experience. Our current membership is around 130 people. Members range in experience from beginners and casual stargazers to experienced telescope makers and astrophotographers. Meetings are held once a month on the Friday closest to the full moon, at Blackhawk Recreational Center , which is located on Higgins Road about one mile west of the intersection of Golf and Higgins Roads, in Hoffman Estates . Meetings normally start at 7:30pm. Non-members are always welcome to attend our meetings. We offer a number of services for members. We have a number of observing sites with dark skies for use of members only, but we also host public observing sessions at these sites. Club telescopes are available for rental, as well as slide sets for programs and presentations. A monthly Newsletter, the Celestial Log , contains information on upcoming meetings and observing sessions, and articles by members. The Northwest Suburban Astronomers are a chartered non-for-profit organization in the State of Illinois.

National Capital Astronomers Serving science and society since 1937. The National Capital Astronomers (NCA) is a non-profit, membership supported, volunteer run, public service corporation dedicated to advancing space technology, astronomy, and related sciences through information, participation, and inspiration, via research, lectures and presentations, publications, expeditions, tours, ( like our past August 1999 Eclipse trip to Turkey or our past February 1998 eclipse trip to Curacao ) public interpretation, and education. NCA is the astronomy affiliate of the Washington Academy of Sciences. All are welcome to join NCA. All who look up to the sky with wonder are astronomers NCA has for many years published a monthly newsletter called Star Dust that is available for members. Besides announcement of coming NCA meetings and a calendar of monthly events Star Dust contains reviews of past meeting and articles on current astronomical events.

69. Amateur Astronomy Magazine News for, by and about amateur astronomers around the world. A quarterly publication with lots of articles and pictures about all aspects of amateur astronomy. http://amateurastronomy.com

Amateur Astronomy Magazine Amateur Astronomy, Observing , and Telescope Making around the world. Home Page Subscription information An Overview of Past Articles Order back issues ... Tectron Collimation Tools Amateur Astronomy Magazine is no longer the new kid on the block. After nine years of publishing articles about telescopes, telescope making, and observing, we have gained the respect and readership of astronomers from around the world. We have recently switched to all new digital printing, and our print and photo quality is remarkable. Check us out. Our Quarterly format is a combination similar to "Telescope Making" and "Deep Sky", two very popular magazines that are no longer published, (only because they were not profitable enough for a large company to take seriously.) If you have missed our first eight years of articles for, by, and about astronomers, observers, and their telescopes, you have missed most of what has been happening in the real world of amateur astronomy. We carry articles that the real amateur astronomers of the world are interested in reading - not articles that are aimed at newsstand market, or professional astronomers. We do not offer the flash of the larger magazines. Instead of having a two page graphic heading a 500 word article, we run the whole 3000 word article so you can read what the author wanted to say. Instead of having a few paragraphs and one photo about an amateur star party, we run a 10 page article with 30 photographs, showing the site and most of the interesting telescopes there. While we cannot print one or two expensive color photos, we are able to publish 15 black-and-white photos in their place. Each issue contains 68 pages - and less than 8 pages contain advertising. We only carry enough ads to help pay the bills. We are subscriber supported. That means that we can say what we want. If a reviewer does not like a product, we can say so, since we don't have to bow to the almighty advertising dollar.

PLANET Monitoring of a Pair of Fold-Caustic Crossings PLANET has successfully monitored both a fold-caustic entry and the subsequent fold-caustic exit in the Bulge binary microlensing event OGLE-2002-BUL-69. Read more here Atmospheric Chemistry of a Star Using the VLT , PLANET team members obtained spectra of the Bulge K giant source of the microlensing event EROS 2000-BLG-5 at several different times during its second caustic crossing (the lens was a binary object). It was the first time that a source star has been resolved at several different phases of a caustic transit. The equivalent width of the H-alpha absorption line first increased slightly as the center of the star egressed the caustic and then plummeted by 30% during the final limb crossing. These changes were not seen in spectra of other stars which also lay on the long spectrograph slit during the observations. The observed changes are qualitatively consistent with expectations from stellar atmosphere models as the caustic differentially magnifies different portions of the stellar face of the target. Observations such as these in a variety of stellar lines are equivalent to atmospheric tomography and are expected to provide a direct test of stellar models. Read more here and see the ESO Press release or read the 1 April 2001 ApJL technical paper which can be downloaded from astro-ph/0011380 Limits on Jovian Planets in the Milky Way Analysis of 43 microlensing events from five years of PLANET team monitoring data has revealed no indication of the short-lived ``wiggles'' that planets orbiting the lens would create on light curves of the backround stars. At the level of the observational uncertainties, all light curves were consistent with those due to an isolated stellar lens. The lack of any detected planetary signature in these 43 events implies that

Welcome to Sky Valley Scopes Honeycomb Core Tubes Wood Scope Plan Images of Telescopes Links ... Available Scopes Custom Built Telescope Tubes Honeycomb Core Tubes It's time for some changes at Sky Valley Scopes. For one, we will no longer be making complete telescopes. It has been fun I am proud of every scope I built and wish I could have kept every one. That has been my quality control, if I want to keep it, it is all right to ship it. When I started building scopes I changed a hobby into a business. I did this because others were interested in what I made and also because arthritis keeps me away from larger projects. Now the arthritis is forcing a change again. I have been getting farther and farther behind because of the decrease in hours of work possible. Those that have tried to order scopes know that I been unwilling to take orders for more than a year and have recently finished the last of the telescopes I will make. At least professionally. From now on I intend to restrict myself to the making of tubes for others to use in scope construction. I am still here to provide support for my prior scope customers. I have been building the upper cages of my scopes for some years out of honeycomb core. Last year I found a way to build honeycomb core tubes in smaller diameters and longer lengths than my previous methods. They are more costly to make than the solid tubes but require less from my arthritis. The advantages of these new tubes are the great reduction in weight and at the same time greater rigidity.
