Please join us for this special event!

November 10th – General Relativity and Gravitational Waves: Ripples in the Structure of Reality

Join us November 10th to hear Don Stevens, Perkins Observatory Director, and long time CAS member, presents: General Relativity and Gravitational Waves: Ripples in the Structure of Reality

Much mythology and misunderstanding surrounds Einstein and his greatest works, the Special and General Theories of Relativity. Though Einstein is no doubt a genius, his theories did not arise from a vacuum. They are built upon the work of other geniuses. These other great physicists and mathematicians are little acknowledged, but without their work and insight Einstein may have been a little remarked patent clerk for the rest of his life. Einstein, like Newton, stood on the shoulders of giants. We’ll look at Einsteins’ theories in a historical context and one of the most profound and recent confirmations of his General Theory – gravitational waves.

Refreshments will be available.  We hope you can come and join us!

October 13th – Star Parties and Sidewalk Astronomy 101

Join us as CAS Vice President Karen Jennings guides us through attending and even hosting your own star party or sidewalk astronomy event.  Halloween and Trick or Treating is a great time to set up a telescope in the front yard and share the Universe with your neighbors.

Also, CAS Member Chuck Jennings will be presenting on Using a Raspberry Pi as a Wireless Connection Between a telescope and Sky Safari.

We hope to see you there!


July 14th, 2018 – Variable Stars

When you look up at the stars, they seem to shine with a steady light.  However, did you know that there are some stars that change in brightness?  These types of stars are called Variable Stars and each of have their own personality in how they change in brightness.  Variable Stars are very important to Astronomy as they assist Astronomers in understanding stellar evolution and determine the distances of far off galaxies.

Long time Columbus Astronomical Society member and Past President of the Society, Jason Hissong will be presenting on these fascinating stars at our next meeting.

Coffee and Donuts provided!


May 12th, 2018 – Astronomical Illusions, Myths, and Misconceptions

Please join us to hear the Director of the John Glenn Astronomy Park and long-time member, Brad Hoehne, speak about some common astronomical optical illusions that even experienced stargazers fall prey to, some historical “memes” that have entered the popular consciousness, and things that amateur astronomers commonly believe that might not be so.

Also, Amateur Telescope Maker Jason Hissong will be available for our Ask Me Anything series. He will be on hand in the Perkins Library at 7:30 to answer questions about Telescope Making.

Coffee and Donuts will be provided!

April 14th, 2018 – Getting Light from the Night

Society Member Isaac Cruz

Please join us for this month’s special guest speaker! Astrophotographer Isaac Cruz presents “Getting Light from the Night”.

This presentation will introduce the concept of histograms as a tool for image analysis and image processing.  We will demonstrate how to process a raw astronomical image using PixInsight, a dedicated image processing program.  To expedite the processing we will follow an abbreviated workflow that will illustrate the basic steps to be followed to successfully process a variety of astronomical images.

Coffee and Donuts will be provided.  We hope to see you there!!!

March 10th, 2018 – Deep Sky Imaging Primer

Astrophotographer Ted Saker
