Astronomy Day Fair & Swap Meet

  • OMSI 1945 Southeast Water Avenue Portland, OR, 97214 (map)

If it’s May, it’s time for our Astronomy Day Fair and Swap Meet. On Monday, May 20 at OMSI from 7:30 – 9:00 p.m., our usual meeting will take a different turn...

Swap Meet & Club Tables

It’s not too late to ask for some table space if you want to bring something to sell or swap.  And if you are in the market for telescopes or eyepieces or imaging equipment, filters, carry-all cases, Barlows, Telrads, a mirror, sky atlas, or any of the myriad other telescope accessories, this is an excellent place and time to stock up on items at good prices. 

RCA will also have a full set of tables and displays from each of the various quarters of our club. We’ll have a Dark Sky Exhibit, the Telescope Library and Workshop will have full setups, we’ll have a Mars Corner and a Kids With Scopes interactive area, as well as our usual Sales Table and Book Library.  It’s a good chance for new members to learn the ins and outs, hallways and doors of the club, as well as for the longer-term members to say hello to all their friends in a setting where we can actually see each other.


In Classroom One, we’re offering “What’s Up There,” by Matt Vartainian, “How to Find Stuff,” by Ken Hose, and “How to Prepare for a Night of Observing” by Alexe Mastanduno.  In the planetarium, Dawn Nilson will offer a Dark Sky presentation and Jim Todd will offer a seasonal Night Sky Report.  Finally, Craig Hlady will once again teach us how to get started in astro-imaging using only a regular DSLR camera.  As of this moment, I’m not quite sure where he will be but don’t worry, I’ll get that sorted out. We expect that Sunriver Nature Center will come again; we’ll have an EAA demonstration, and if I can find room for myself, I still want to do a workshop on earning observing certificates.

This is an event we advertise to the public more than usual, so there will be lots of people getting into the spirit of astronomy that we don’t always meet.  I hear there will be a classroom of science students. Let’s hope so. It’s going to be a good time. See you all soon.
