Astro-Imaging: Exploring the Wonder of the Night Sky
with Joe Dougherty
Ever wonder how the images of the Milky Way, nebulae or distant galaxies that we see in magazines, television, or posters are captured? You might be surprised to learn that it is not as simple as taking a camera out to the back yard and just “pointing and clicking.” It requires the harnessing and integration of telescopes, computers, cameras, software and even a bit of artistry.
Astro-imaging allows astronomers to see details of celestial objects that are hidden using a telescope alone. Imaging techniques can enable viewing deep space objects even with the brightness of a full moon. This talk explores the basics of astro-imaging. You will be taken behind the scenes to understand the equipment, processes, tools and techniques today’s imagers use to capture and create astonishing pictures of astronomical objects. Viewers will be treated to dozens of actual photos taken by members of the Litchfield Amateur Astronomy Club over the past several years. We will explore many of the varied types of astronomical objects through a pictorial tour of the night sky.
Joe Dougherty, president of the Litchfield Hills Amateur Astronomy Club, has specialized in astro-imaging for nearly ten years. He has given numerous presentations over the years on imaging techniques, processes, software and on improving image quality.
