More information will be provided soon.
Pre-registration for this event is required. Are you new to observing? Have you always wanted to take a telescope out but didn't know where to start? Come learn about how telescopes work, how to find constellations in the sky, and how to point a telescope for a closer look at deep-sky objects. 8 slots are available. Please email firstname.lastname@example.org to reserve your spot and for further details.
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.
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!
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.
New members are welcome to meet in the OMSI Planetarium at 6:30 before the General Meeting for an orientation and introduction to Rose City Astronomers.
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.
Slides from Our General Meeting
Public Star Parties are held so that we can share our telescopes with anyone who wishes to attend. Since star parties are held at night in the dark, a few common courtesies will go a long way to making sure that everyone has a good time and a safe time.
RCA has a long tradition of small observing parties — it’s part of why the club was formed. RCA Club star parties are for members and their families and guests invited by members. The purpose is have a smaller, quieter event where attendees can spend an entire night observing or imaging without interruption. They are often in remote rural areas where conditions can be primitive at best.
The purpose of this Code of Conduct is to help insure your safety and the safety of others, to contribute to the enjoyment of club events, and to foster an atmosphere that will encourage other people to join RCA. These standards of behavior apply to club events, public events and at any volunteer or outreach events.

Are you new to observing? Have you always wanted to take a telescope out but didn't know where to start? Our second Intro to Observing class of the 2019 season is coming up in August! Come learn about how telescopes work, how to find constellations in the sky, and how to point a telescope for a closer look at deep-sky objects. 8 slots are available. Please email email@example.com to reserve your spot and for further details.
This class is ideal for members who have never or rarely used a telescope and would like to become more comfortable observing the night sky. You do not need to have a telescope to attend and participate. We will be providing and observing with Dobsonians, so if you have a Dobsonian with a Telrad or dot finder, you are welcome to bring it (please check with us first!). Everyone will be able to work with a telescope throughout the evening. Responses exceeding the 8 available slots will be placed on a waiting list.
The Telescope Library has acquired two 7-amp hour Power Tanks which can supply 150 watts of AC power. Increasingly, telescopes are coming to rely on electricity, and as we move to more contemporary telescopes in the library, one deficiency of our collection that is becoming clear is the lack of electric power supplies that we can loan out with telescopes. While many of our instruments can operate on AA or D size batteries, is this expensive, either for RCA, or for each borrower. Not only is the cost high, but the lifetime of batteries is small, some telescope really draw power. Some scopes can draw all the power out of the batteries they operate with in a single night of observing, maybe less. By acquiring power supplies with more capacity, we provide reliable sources of power for our telescopes, and the payback time for these power sources is rapid — under a year, given the number of loans we are making.
Artificial Satellite Constellations: A New Threat to Astronomy and Dark Skies? International Dark Sky Association (IDA) has gone on record opposing satellite clusters. An urgent response is needed before more clusters are launched. With many astronomers on break or otherwise tied up for the summer, help is being sought from amateur astronomers and astrophotographers. One thing you can do to help the effort to curb the proliferation of these clusters is to post time and location data and photos of the cluster to the RCA forum (I will start a thread for Starlink under the imaging SIG). I will get these photos to the active members of the committee assigned to respond to SpaceX. RCA and IDA will also conduct social media outreach using these images. If you are interested in assisting with modeling efforts, let me know and I will put you in touch with the appropriate team member. Stay tuned for more information.
Status of International Dark Sky Places
By far, the most effective advocacy tool that IDA has found in its tool box is designating International Dark Sky Places (IDSP). As of June 2019, there are 122 IDSP’s world-wide totaling 22 million protected acres. Fifteen more IDSP’s are expected to be designated by the end of 2019. Because IDSP’s draw so much attention to dark sky issues as well as providing dark sky preservation, RCA’s Board has made helping to designate “Oregon’s First IDSP” one of its goals in the next two years. There are a few candidate sites where RCA has confirmed that the land managers are in favor of designation and where required studies in support of an application have either been initiated, nearly completed, or can be quickly conducted.
