On Sunday evening of September 27, 2009 the Astronomy Associates of Lawrence held a public observing session at Prairie Park Nature Center. Rick and Michael Heschmeyer, David Kolb, Rex Powell, George Brenner, William Winkler, and Barbara Anthony-Twarog attended and brought 5, 8, 12 and 13 inch telescopes. A number of the local high school students attended the session. The lights in the parking lot did not get turned off as expected so we had to deal with a lot of bright lights. A couple of the scopes were dragged over to where the lights were not as bad and we managed to show a few faint fuzzies. The Moon and Jupiter were easy targets for the scopes set up under the parking lot lights.

On Sunday evening of March 29, 2009 the Astronomy Associates of Lawrence held a public observing session at Prairie Park Nature Center. Rick Heschmeyer and David Kolb brought their 8 inch telescopes. The weather did not look very good but it cleared enough for almost an hour to observe the crescent Moon, Saturn, and the Orion Nebula. One other club member, George Brenner, stopped by shortly after 9 PM, but no one from the public showed up while the telescopes were set up. A local high school student showed up at 9:40 PM after the clouds had obscured everything and the scopes were put away.

On Thursday February 5, 2009 the Astronomy Associates of Lawrence had a table at the Douglas County Science Fair to promote the activities of our group. We had a couple of tables of handouts and astronomy books and charts. Bill Winkler brought one his telescopes and had it set up.

On Sunday evening of February 1, 2009 the Astronomy Associates of Lawrence held a public observing session at Prairie Park Nature Center. Rick Heschmeyer and David Kolb brought telescopes ranging in aperture from 5 inches to 8 inches. I had my vintage 8 inch Criterion Dynamax with a Watec 120N integrating video camera pointed at M42. The image of M42 on the TV screen was bright and showed a lot of faint detail, just like a picture out of a book . Rick had his 5 inch Celestron pointed at Venus and his 8 inch Celestron was pointed at the Moon. A couple of families and several Lawrence High students showed up despite the Super Bowl game that was playing that evening.

On Friday evening of November 21, 2008 the Astronomy Associates of Lawrence held its annual Cub Scout Astronomy event at Wescoe Hall on the KU campus. About 281 scouts along with their parents attended the event. From 7 to 8 PM Rick Heschmeyer gave a presentation to the scouts in 3139 Wescoe. From 8 to 9 PM the scouts observed through a number of telescopes. Several members of the club brought telescopes ranging in aperture from 5 inches to 13 inches. Unfortunately, the weather did not cooperate. It was cloudy at first and then it cleared off for a little while. Half way through the observing the clouds came back. I had my 8 inch Criterion set up, with my Watec 120N integrating CCD camera, trained on M31. Large numbers of scouts were able to see M31 at the same time. Bill Winkler showed a few scouts how to locate Polaris and Rex Powell showed a number of scouts close up views of windows in the library.

On Sunday evening of August 31, 2008 the Astronomy Associates of Lawrence held a public observing session at Prairie Park Nature Center. Several members of the club brought telescopes ranging in aperture from 5 inches to 13 inches. Jupiter, and a number of Messier objects (M32, M13, M57, ...) were observed. The parking lot lights were supposed to have been turned of by 8:30 but they stayed on until about 9:30. When the lights went off we pointed the telescopes to the deep sky objects and we were actually able to see the Milky Way. I had my vintage 8 inch Criterion Dynamax set up as well (not pictured). When it seemed like the parking lot lights were not going to be turned off we moved my Dynamax out of the parking lot and into a darker area in the weeds behind some trees in order to provide some views of M13 and M57.

On Wendsday evening of June 20, 2007 the Astronomy Associates of Lawrence held a public observing session after the Lawrence Band concert. Several members of the club brought telescopes ranging in aperture from 5 inches to 13 inches. Bruce Twarog helped members set up their telescopes. Jupiter, Saturn, Venus, and a waxing crescent Moon were visible. During the middle of the observing session Rick Heschmeyer pointed out the International Space Station and the space suttle Atlantis as they made their way across the sky.

On Friday evening of March 02, 2007 the Astronomy Associates of Lawrence held a workshop for the Lawrence Girl Scouts, which allowed the participants to earn their sky search badges. Several indoor activities were held, and included building star wheels, lunar phases demonstrations, and telescopes. After the indoor activities were completed a couple of telescopes were set up outside and the girls were allowed to view the Moon, Saturn and the Orion Nebula. They also learned to identify some of the brighter Winter constellations and learned to use the star wheels that they had made.

On May 12, 2006 members of Astronomy Associates of Lawrence traveled to Auburn, Kansas to see the 27 inch telescope that once was part of the University of Kansas Observatory in its new role as an asteroid patrol telescope. The only remaining part of the original telescope are the optics. The telescope optics were donated to the Northeast Kansas Amateur Astronomers´ League (NEKAAL ) for use in their NASA funded asteroid search program. About six members of AAL made the trip out to the Farpoint Observatory and watched the NEKAAL members as they observed several near earth asteroids in order to obtain better positional data. Here are some pictures of the 27 inch telescope.
