Astrophotography - Colors of the dark sky

by Ken Crawford

Note date/location of meeting. We will meet with Nevada Co Camera Club at Unitiy in the Gold Country Church 

This presentation will demonstrate how color, structure, and contrast is managed, processed, and enhanced in deep sky astrophotography to show the amazing structures and colors of the universe.  But is it real!?!?!   We will look at both “natural color” and “representative color” examples to see.

This talk will also cover research that was done searching for galactic tidal streams which are the remnants of galaxy mergers.  This galactic archaeology shows that real science can be done by amateurs with modest equipment, clear dark skies, and dedication.  Ken will demonstrate some of the methods used to reveal these very faint structures. 

Ken is one of the founders of the Advanced Imaging Conference and was the recipient of the Hubble Award in 2015. He was invited to participate in NASA’s "Astronomy Picture of the Day" committee. His star stream images have been used by professional astronomers. Ken's website is http://www.imagingdeepsky.com/

North Pole, South Pole

by Kurt Simon

You might expect the rocky inner planets (Mercury, Venus, Earth and Mars) to have similar magnetic fields since they formed in much the same way.  They do not. Earth has a far larger field than any other rocky planet; in fact, no magnetic field at all has been detected on Venus and the other rocky planets have only tiny magnetic fields. Not only is Earth’s field far larger, for many years the wandering of the poles was considered one of the great unsolved problems in science. Today, the study of our home planet has unraveled much of the mystery of the wandering pole and the elusive “pole flips” whereby the north and south poles reversed position. Kurt will describe the development of our understanding of the interior workings of Earth and the fascinating science that has led to where we are today.
