September 14th, 2019 – Telescope Basics

At our September meeting, we are offering a program on Telescope Basics. Experienced members will give mini-presentations on telescope collimation, finder and polar alignment, magnification and field of view, and useful accessories. Aimed at newbie amateur astronomers, even veteran observers may learn a trick or two. For an autumn treat, we’ll order pizzas after the program, and hopefully enjoy clear skies to practice what we have learned.

We hope to see you there!!

August 9th, 2019 – CAS picnic

CAS Members enjoy the annual picnic!

Please join us for out annual picnic out

Nothing feels more like summer than a good picnic and fireworks. We hope to have both at our annual August picnic meeting. The picnic will feature BBQ and sides from City Barbeque. Members are also encouraged to bring a dish to share- vegetable dishes for our vegetarians, traditional and nontraditional sides and desserts are all desired. Hopefully we will have clear skies, but if not we will take shelter inside Perkins Observatory to enjoy our feast. We will begin to set up at 4 pm and begin eating by 6 pm. We will also attempt to take our annual group photograph, so start practicing your smiles now!

            If you are wondering about the promise of fireworks, those will come later, after dark. Our picnic will fall near the beginning of the annual Perseids meteor shower.  Although a bright Moon will wash out many of the meteors, the brightest will still be impressive. So bring a camp chair, bug spray, some food to share, and an appetite. Hope to see you at the picnic!

July 13, 2019 – 3D Printing and Astronomy

Long time Society member, Jason Hissong, will be presenting on 3D Printing and Astronomy. From Astrophotography accessories, to telescope making, 3D printing has become a great way to make custom parts for Astronomy. Jason will be covering the various aspects of 3D Printing, and how many take advantage of this technology for Amateur Astronomy purposes.

8pm at Perkins Observatory. Refreshments will be available. We hope to see you there!

June 6th, 2019 – Swapmeet!

It is that time of year again where we have our annual swap meet!

Bring cash to buy and and your astronomy-related gear to sell or swap. We will provide tables to set up outside, or inside in the event of rain. Setup begins at 5 pm, and the swap meet begins at 6 pm. Around 7:30 to 8 pm we will order pizzas. If by some miracle we have clear skies, we will observe, too!

Start looking through your gear now!Hope to see you Saturday afternoon!

May 11th, 2019 – Astronomers as Citizen Scientists

Society Member Isaac Cruz

Please join us to hear long time CAS member, Isaac Cruz present on “Astronomers as Citizen Scientists.” Astronomy is the only amateur endeavor that provide a surprising number of opportunities for an individual to contribute to science.  In this lecture we will learn about a variety of ways Amateur Astronomers can contribute to science.

Isaac Cruz’s Bio:
Retired Electrical Engineer
Past President of CAS
Leads the CAS imaging group CASIS
Lectured at CAS, OSU, Otterbein University, and the Metropolitan University at Puerto Rico
Passionate astrophotographer. 
Work published in various magazines and books.
Citizen Scientist, with published research and exploration work done on variable stars, eclipsing binaries, exoplanets and lately, extra-galactic supernova search in cooperation with OSU.

Coffee and Donuts provided!

April 13th, A Glass Act: Refractors

The Late Ron Ravneberg, CAS member and Telescope Maker observes with his refractor.

Join us as long time observer and CAS member, Phil Creed, presents on the basics of the refractor telescope, pros/cons of refractors, a bit of the history of refractors and modern trends in commercial refractors.  He will cover the dreaded chromatic aberration and get in-depth on many bits of refractor lore and a few “refractor myths”.

Coffee and Donuts provided!

March 9th, 2019 – Sex, Death, Random Violence, and Wee-wee: The Real Story of the Sky.

Join us for our next meeting as Tom Burns, former director of Perkins Observatory, discusses a peripatetic (i.e., “rambling”) tour of the ancient myths connected with the stars and planets from various cultures. We’ll look at our very human concerns as they are reflected in the starry vault. Come for the stories. Come to get a startlingly different view of the night sky.  Come for the weirdly inspirational content. Come for the free donuts.

Not-so-brief bio: Professor (yes, that’s right, believe it or not) Tom Burns has been a member of the CAS for a very, very long time. He is a two-time winner of the Bud Stewart Award and was deeply honored to receive the Jane Gann Lifetime Achievement Award a few years back. Currently, he is the club Secretary. 

He directed Perkins Observatory for a quarter of a century. He has participated in thousands of public astronomy programs over the decades. He has been writing a weekly column on stargazing, first for the Columbus Dispatch and now for the Delaware Gazette, for 32 years. 

He is old and tired, but he still manages to teach a couple of classes at Ohio Wesleyan University every year. His semi-retired teaching load includes a class in Popular Science Writing, in which there is occasionally even a reference to the science of astronomy.

FEBRUARY 9th, 2019 – “COMETS” by James St. John, Geologist and Instructor at Ohio State University’s Newark Campus

“COMETS” by James St. John, Geologist and Instructor at Ohio State University’s Newark Campus.  James has previously presented to the CAS on meteorites and meteor impact sites. This month, James will provide an overview of what is known about comets. Please join us February 9th, 2019 at 8 pm as James surveys historical comets and shares the latest insights provided by spacecraft missions into these visitors to the inner solar system. Refreshments provided.

January 12th 2019 – Paul M. Sutter Presents “Your Place in the Universe”

The Columbus Astronomical Society is pleased to announce that Paul M SutterAstrophysicist at The Ohio State University, Chief Scientist at COSI, and host of the Ask a Spaceman! podcast, will be presenting on “Your Place in the Universe: Understanding Our Big, Messy, Existence.”

He will have his books on hand for purchasing and signing.  Please come early as parking is limited.

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!
