Rose City Astronomers (RCA)
Providing Astronomy Community for the Portland Metro Area
If you need help with a telescope project, need to clean or align your optics, or just want to talk about telescopes, come to the workshop. Activities include telescope building from scratch or a kit, telescope setup, cleaning, aligning, adjustment, and help using your telescope.
Whether you're a beginner, intermediate or advanced astro-imager — whether you're using a CCD, DSLR, point-and-shoot or film camera — this group can help you achieve better images with less effort and frustrations.
Through a partnership withClackamas Community College, RCA offers access to the Haggart Observatory to members of the general public.
In keeping with our annual tradition, the December meeting of the Rose City Astronomers will be a holiday buffet and social gathering for all RCA family members to be held in the OMSI Auditorium. Tables will be set up in the main auditorium and plates, silverware, and some beverages and ice will be supplied by the club.

Slides from November Meeting
For the first time in Earth's history, our planet is experiencing a confluence of rapidly accelerating changes prompted by one species: humans. Climate change is only the most visible of the modifications we've made--up until this point, inadvertently--to the planet. And our current behavior threatens not only our own future but that of countless other creatures. By comparing Earth's story to those of other planets, astrobiologist David Grinspoon shows what a strange and novel development it is for a species to evolve to build machines, and ultimately, global societies with world-shaping influence.
