Eugene Astronomical Society

Eugene Astronomical Society The Eugene Astronomical Society has been doing astronomy education and public outreach for many years. Member interests vary.

What sets us apart is our commitment to sharing the EYEPIECE with the public. We do "Star Parties!" We are happy to partner with community groups to put our experience in astronomy, observing, telescope technology, education and outreach to work for your project. Solar observing, lunar observing, technology, deep sky objects, astrophotography, and slide presentations for groups, and that represents a partial list.

Conditions look good for tonight's First Quarter Friday star party! You'd never guess it right now, but a big three-hour cloud gap is expected exactly when and where we need it. See you at Emerald Park!

We are truly sorry friends. We really love doing these events and hate to have to cancel.

Our August 15 Dark Sky Star Party is cancelled due to clouds and smoke. Watch this space for info about our next star party possibly a rescheduled date in September.

What goes into our decision to cancel a star party? Here's a short dive into one of the weather forecast tools we use, plus some perspective on what goes into our planning process from our club president, Robert Asumendi.

Rebuilding a 17-Inch Telescope
by Lauren Wingert

Lauren Wingert is our club’s “gadget girl.” She has built dozens of amazing astronomy tools, fromsimple dew shields to a binocular observing chair to a fabulous (and functional!) replica of the Hubble Space Telescope. Many of her designs have been featured in Sky & Telescope magazine.
Last December she acquired a 17.5-inch Coulter mirror from a friend. The mirror had been refigured by the late Steve Swayze, a master mirror-maker, so it was near perfect. Trouble was, the scope it was in weighed 120 pounds. It was rebuilt from the original Coulter cardboard tube and particle board, but it was still heavy as lead. So Lauren took only the mirror and set out to build a lighter, more portable scope to house it.
At our August 20th meeting she will
show us what she’s done and how she did
it. Comesee what she built and listen to her describe how she built it.
At our meeting we will also have Ken
Martin’s slide show of astrophotos taken by EAS members displayed in all their glory on the planetariumdome.
The meeting is at 7:00 on Thursday,
August 20th at the Eugene Science Center
planetarium, 2300 Leo Harris Parkway in Eu-
gene (behind Autzen Stadium).

The weather forecast looks great for our star party tonight at Emerald Park (1400 Lake Dr. Eugene, OR 97477). Sunset is at 8:45 so you can arrive then and watch the Moon until the stars come out. The telescope area is on the basketball court marked by the blue star in the photo. We hope to see you there!
