BAS Mission Statement

The Bluewater Astronomical Society is a group of amateur astronomers that love stargazing and sharing the hobby with others. We promote astronomy education in the Bluewater counties of Bruce and Grey by holding star gazing sessions, lectures and astronomy events for anyone interested in learning more about the night sky. We have a large, modern facility, the ES Fox Observatory on the grounds of the Bluewater Outdoor Education Centre of the Bluewater Education Foundation. There we show, to young and old alike, views of the Moon, planets, star clusters, galaxies and nebulae. Join us at our public stargazing sessions (see below or click on COMING EVENTS for dates to have some heavenly views at one of the last truly dark sky locations in Ontario.

The BOEC was declared Canada's 15th Dark Sky Preserve in Nov, 2012. At the ES Fox Observatory, we have a large reflecting telescope (a 28-inch Webster) and a 10-inch SCT on a GOTO mount that we use regularly in our public viewing sessions.

CLoud cover prevented observing at the Fox Observatory but BAS members took to their cars and found holes in the overcast and succeeded in seeing some parts of the Sep 27 Lunar Eclipse. Some even managed to get images. A selection is provided below:

From Our Astrophotograhers:

This image is a 3-1/2 hour record of the rotation of the northern sky around Polaris. A total of 572 images of 20 s each were made to record the sequence. Several satellite and aircraft trails are visible as well. The ES Fox Observatory is illuminated in red in the foreground. Image Sep 9, 2015 John Hlynialuk.

Image above was taken at the ES Fox Obs. from 10:55 pm on Sep 9 to 2:26 am Sep 10, 2015. This is a stack of 572 images -each one was a 20 s exposure at ISO 2000, f/3.5 with a 15 mm lens on a Canon 60Da camera. The shot shows the rotation of the northern sky counterclockwise around Polaris which is the short trail in the middle of the circles at top. There are several aircraft and satellite trails in the image, the most prominent one going from lower left towards Polaris is an aircraft. The red streaks at bottom are me with my red flashlight going towards the camera to check at various times. The red lights also illuminate the south wall of the observatory as well as the back of the Webster telescope trailer.
