Astronomy Club of Tulsa

If you think you’d like to actually get involved and learn about astronomy, .the Astronomy Club of Tulsa, founded in 1935 is still going strong at sharing and building our hobby. There are monthly meetings at TCC Downtown during the school year; and there are open to the public public events monthly at venues like Bass Pro Shops and River West as well as the Clubs RMCC Observatory southwest of Mounds, OK - about 35 minutes from south Tulsa.

If you are interested in observing the moon, planets, or other objects in the night sky click on these links.

Contact Star Corral

Stargazing on Friday (weather permitting) May 13, 2011- West End of 200 Yd. Range Firing Line.

I'll be set up shortly after sunset.

The moon and Saturn will be great to look at, and we'll also be able to see many other interesting objects.

If the weather is not conducive to observing we’ll try again on Saturday Night May 14.

 The Great Orion Nebula Messier 42

I took this image with an camera specially made for astronomy.  I hope to get better at imaging in the future.  M-42  is easy to photograph, most are much more difficult and time consuming.

Any OCRGC member can bring guests. The gate will no longer be locked open during astronomical observing. Until further notice, any and all future events will be limited to members and their invited guests.

Astronomical Observing at Oil Capital

The Internet is the world’s most powerful astronomical instrument; click on a telescope!


Astronomy has changed dramatically in my lifetime. Albert Einstein and Edwin Hubble both made monumental contributions to astronomy, but it is people like Carl Sagan and Neil Tyson who have introduced astronomy into the mainstream of our culture. I encourage  you to click on these pictures and begin a personal journey.  Also visit History Channel and PBS Web Sites.

Oil Capital Astronomy Map and Directions

The Star Corral Astronomy Program makes astronomy accessible to Oil Capital members, their guests, and others having any degree of interest in observing the night sky. The name Star Corral is really a playful way of looking at a given patch of sky  - the one in the field of view of a telescope.. The “corral” is that big round circle full of stars and other objects .we see when we peer through the eyepiece. The Star Corral is a special place that exists for anyone who sits on the top rail watching what’s going on. For most of us it can easily become a very rewarding and memorable experience. I’m sure the Proprietor is glad we enjoy his work as much as we do.

Now and in the future, an “event window” of 12 to 14 days will be posted at least 7 to 10 days prior to the third quarter moon of each lunar cycle.   In it’s 28 day orbit of Earth, the moon progresses east and rising 51.5 minutes later each night -  The glare of the full moon(round appearing)  makes observing deep sky objects beyond our solar system difficult.   
The solution is to wait until 6 or 7 days after the full moon  before setting up an all evening observing session.   7 days x 51.5  minutes = about 6 hours.  Moon phase is as predictable as weather is unpredictable.
