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!
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.
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.
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!!!
Are you interested in imaging Deep Sky objects like nebula and galaxies but are struggling with where to begin? Do you have questions about gear, equipment and software? Join us for Astrophotographer Ted Saker’s presentation as he reviews best practices and techniques he has acquired over the years to help you achieve optimal results! Refreshments and donuts will be available!
As with all CAS meetings, no tickets are required to attend.
Please join us at 8:00pm, February 10th, 2018 at Perkins Observatory for a presentation by James St. John from the Ohio State University at Newark Geology Department. James will discuss the geology and features of all the planets and major moons or our Solar System. Plus hints of some major changes in the configuration of our Solar System. You will not want to miss it!
Refreshments will be provided and if it is clear, please feel free to bring a telescope or binoculars to observe with afterwards.
