  • 9:15 to 9:30 am Sign-in  
     
  • 9:30 am: Solar Eclipses and Transit Excursions,
    Greg Babcock
    • I have been on 4 Total Solar Eclipse Excursions and I went on the 2004 Venus Transit Excursion in Greece. I imaged with Film Cameras on the first 3 Eclipses. For the 2004 Venus Transit and 2009 Asian Total Solar Eclipse, I imaged using simple “Webcam type” Cameras. I will discuss some of the image processing that took place. Also, I will briefly discuss some of the touring that took place that comes with traveling to see and image these events. Finally, I will cover the up-coming, Annular Solar Eclipse and Venus Transit. These will occur about 20 days apart in May and June of 2012. Both will be visible from the Pacific Northwest.

Sunday May 6, 2012

  • 10:00 am Optical Configurations for Astrophotography,
    Richard Berry
    • Optics are one of the keys to first-rate astro-imaging. After introducing the requirements for good imaging, I will describe the designs commonly used by amateurs, present a brief analysis of the performance that can be expected from a well-made instrument of each type, and discuss the weaknesses and strengths of each design. Please note I will not talk about the merits of different manufacturers, but instead about the properties of each type themselves based on inescapable physical and optical limitations of the system design. Included are achromatic refractors, apochromatic refractors, Newtonians, Cassegrains, RCs, SCTs, CDKs, and RHAs.

Photometry precision testing by Ken Hose

  • 4:00 pm Asteroid Light Curves and Occultations,
    Joe Garlitz
    • Asteroids provide a good opportunity for amateurs to make unique and valuable measurements of astronomical objects. When an asteroid occults a star, it is possible to make a direct measurement of its profile's size and shape. An asteroid's rotation period can be measured by taking a series of images and extracting the data with easily used software. Measuring the rotation period of an asteroid helps classify the object, determine its rotation orientation and with enough observations, allow a determination of its shape.

Richard Berry

Richard Berry

Richard Berry is an author, editor, and software programmer focused primarily on amateur astronomy. His books include a classic, Build Your Own Telescope, a popular introduction to observing, Discover the Stars, the acclaimed manual for big Dobs, The Dobsonian Telescope (with David Kriege), and the book best known to NEAIC attendees, The Handbook of Astronomical Image Processing (with Jim Burnell), which includes the Astronomical Image Processing for Windows (AIP4Win) software widely used for image processing as well as both photometry and astrometry.

At age 13, Richard built his first telescope (a 6-inch f/7 Newtonian) and moved on to construct an 8-inch f/10 planetary telescope, a 6-inch RFT, a 12-inch f/7 Newtonian, and an 8-inch Dall-Kirkham Cassegrain. He observed all of the planets, most of the Messier objects, and made deep inroads into the NGC catalog. In those distant days of darkroom chemistry and bromide paper, he specialized in lunar and planetary astrophotography.

After majoring in astronomy for his B.A. degree, Richard went on to present a thesis on photoelectric photometry earning an M.Sc. in astronomy. In the technology world, he has designed rocket payload instrumentation, measured air pollution (ozone and hydrogen sulfide) using a laser beam, and tested key components for the Ultraviolet Absorption experiment (MA-059) flown aboard the Apollo-Soyuz Test Project.

Switching from technology to editing, Richard served a ASTRONOMY magazine's Technical Editor, then Editor, and finally Editor-in-Chief, for sixteen years, and played a key role in building the fledgling magazine's circulation from 38,000 in 1976 to its peak at 252,000 in 1988. During his years at ASTRONOMY, Richard built a strong, effective, and knowledgeable editorial staff, and worked tirelessly to ensure that manufacturers present only honest and accurate claims in their advertisements.

During his years at ASTRONOMY, Richard founded and edited Telescope Making, a quarterly magazine devoted to the community of amateur telescope makers. From 1978 through 1991,Telescope Making introduced its readership to the Dobsonian telescope, the Poncet platform, tilted-component telescopes, and many examples of outstanding amateur observatories.

From 1992 to the present, Richard has written and coauthored a string of books about telescope making, imaging with CCD cameras, and image processing. He has given countless talks and participated in workshops at conferences around the world. His current book, due out this summer or fall, is a comprehensive ray-trace analysis of the telescope, eyepiece, and astrographic camera designs available to today's amateur astronomer.
 


Joe Garlitz

Joe Garlitz

Joe became interested in astronomy while in gradeschool, seeing the moon through a telescope he was hooked. He purchased an Edmund’s 3" reflector while in Jr. High and built an 8" Newtonian in highschool. He received a B.A. in Physics and worked on the Skylab Program for 5 years in Denver. In 1973 he and his wife move to Eastern Oregon. It took 2 decades before he was able to build the observatory of his dreams. As an amateur astronomer, Joe’s primary interest is in science. So far he has posted 38 exo-planet transits to the TRESCA database, viewed four dozen asteroid occultation events, measured three dozen asteroid rotation periods. While participating in a Pro-Am campaign looking for possible exo-planet transits of white dwarf stars, he discovered an un-catalogued eclipsing binary. Joe enjoys traveling to exotic places nearly as much as astronomy. Among his passport visas are India, Libya Egypt and Russia.
 


Neil Heacock

Neil Heacock

Neil Heacock is an IT professional who moved out of the city for the first time in 2003. After living in LA, Seattle and Portland, he moved to somewhat more rural area of Clark County and really saw the stars. This birthed a strong interest in astronomy which has continued to grow and develop ever since. In 2006 Neil began to dabble in astrophotography and after attending the 2007 Northwest Astrophotography Conference his imaging stared a path to maturity. Neil is still an avid visual observer but with such amazing and easy to use imaging systems available he now images with one setup while observing with another. He runs the Yahoo DSLR Astro Image Processing group with 350+ members and mentors other astrophotographers both local and afar.


Tim Crawford
