To inform, inspire and keep up to date on current research and the state of our knowledge of the universe. This SIG meets in a private home so the address is not published on our website. Our Cosmology SIG leader can be reached through the Contacts page for more information.
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.
Join us at noon on the first Fridays of every month for good conversation and good food at McMenamin’s on Broadway, 1504 NE Broadway, Portland. Everyone is welcome!
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.

Jill Tarter thinks that Craig Venter and Daniel Cohen may not have been bold enough when they declared in 2004 that the 21st Century would be the century of biology. “I think the 21st Century is going to be the century of biology on Earth—and beyond,” Tarter declared during a talk at last month’s meeting of the Rose City Astronomers in Portland, Oregon. Tarter, the Bernard M. Oliver Chair for SETI at the SETI Institute and former director of the Center for SETI Research, thinks there are many ways we might find extraterrestrial intelligence.
EAA (Electronically Assisted Astronomy) is an exciting, emerging new form of astronomy that our club members are embracing at a quick pace. EAA offers a hybrid form of observing, that mixes near-real time imaging (photography) with traditional observing through the use of specialized equipment. Essentially, a camera replaces the eyepiece, but instead of long-exposure imaging (what many imagers do to produce those stunning photos of deep space objects, but it often takes hours of capture time and then equally long periods of post-processing on the computer for many days after the capture), the EAA camera takes a sequence of very short exposures, and then a software program quickly stacks and stretches the images, using a few configurations/instructions preset by the observer, to yield often stunning views of objects.
We are very pleased to announce that a delegation from the board of the Geologic Society of Oregon Country (GSOC), including our own Paul Edison-Lahm, will be joining us for our May 11-13 Camp Hancock star party. The “GSOCers” will be sharing their knowledge of the local John Day basin geology and will in turn be learning from us about dark sky observing. All board members have had training in star party etiquette and their impact on parking and cabin space should be minimal.
RCA, GSOC, and OMSI share a long history at Camp Hancock originating with its namesake Lon Hancock, an amateur geologist and charter member of GSOC. Lon devoted many years to exploring the paleontology of the John Day region and was the first in Oregon to discover an Eocene vertebrate fossil: a rhinoceros tooth embedded in a nut in the nut-beds above the camp. A 1951 OMSI field trip led by Hancock and other GSOC members would quickly become “Camp Hancock” and plant the seeds for the OMSI Astronomers, a parent organization to RCA.
