Upcoming Events Finding the Observatory
Planetarium Show “Climbing the Cosmic Distance Ladder” at Ritchie Observatory March 11, 7:30 p.m. Free to members, $2.00 donation suggested for nonmembers, $5.00 for families.

When astronomers say some object is so many million light years away, how do they know that? Astronomer Steve Ruhl will climb the cosmic distance ladder and show how astronomers, past and present, determine distances to objects.

If the sky is clear, astronomers will be on hand with telescopes for public star-gazing.

The Battle Point Astronomical Association (BPAA) is a non-profit amateur astronomy organization. We operate the Edwin E. Ritchie Observatory and John H. Rudolph Planetarium in the Helix House at Battle Point Park, 11299 Arrow Point Drive NE, Bainbridge Island, WA.

March 11th
Have you ever wondered how Hubble gets all of its goregous photos back to Earth? We will learn how the process works, as well as transmit our own images to each other, paint our own universe photos and more!
New 4-5PM show takes the place of our 6-7PM show from now on. Two shows, 4-5 and 5-6PM, suggested $5 donation for supplies, fun for the whole family!
Directions: From the Ferry, go north on 305, left on High School Road, right onto Fletcher Bay/Miller Road, left onto Tolo Road, right on Battle Point Drive, and right into the park. From Agate Pass Bridge, go south on 305, right on Day Road, left on Miller Road, right onto Tolo Road, right on Battle Point Drive and right into the park. If you approach the park from Arrow Point Drive, skip the eastern entrance, which will not take you to the Observatory, and drive around the park, continuing on Arrow Point as it bends right past the eastern entrance, left around the north end of the park, and left again heading south. Turn left into to the western park entrance, and follow the drive to the Observatory.

We're back... well getting there.

We have been hacked and we are strugling to get back up. It was so bad that as we were trying to update and fixed the site, the hackers were actively changing the site underneath us. We had to kill the old website. We are working to get everything back up. Please check our facebook page also it may be more current at the moment.
