Robert Gendler is a physician who began doing CCD astrophotography in the early 1990s. He spent his first decade imaging from his home using a portable setup. With advances in Internet accessibility and worsening light pollution at home, Gendler began imaging remotely in 2005 from observatories in the southwestern United States and later in Australia. Gendler now spends much of his time mining professional astronomical archives and assembling unique composite images from a wide variety of data sources, including the Hubble Space Telescope, Japan's 8.2 meter Subaru Telescope, and various ground-based professional and amateur systems. Gendler has published four books on astrophotography including A Year in the Life of the Universe (Voyageur Press, 2006), Capturing the Stars: Astrophotography by the Masters (Voyageur Press, 2009), Treasures of the Southern Sky (Springer, 2011) and most recently Lessons from the Masters: Current Concepts in Astronomical Image Processing (Springer, 2013). In 2008, he was featured in the PBS documentary Seeing in the Dark by Timothy Ferris, who referred to Gendler as "one of the great astrophotographers in all of history." Gendler's images have been featured in two national stamp series (United Kingdom 2007, Germany 2011). In 2007 he was the recipient of the "Hubble Award" at AIC. His images have been featured by the NASA site "Astronomy Picture of the Day" over 100 times. This work has earned him international recognition and has led to professional collaborations with NASA's Hubble Heritage team on two Hubble Space Telescope projects (M106 in February 2013, and M31 in February 2015). R. Jay GaBany, by profession, is an eCommerce product manager working in California and the recipient of five patents for innovations in his field. Over the last decade he has earned a reputation as an elite astrophotographer. His work has been highly recognized internationally. He has also distinguished himself by his collaborations with professional astronomers such as his work with Dr. David Martinez-Delgado on tidal streams produced by galaxy mergers. GaBany has coauthored several significant scientific papers on the subject. For his contributions at the professional level he was given the Chambliss Award by the American Astronomical Society. Among his many other accomplishments GaBany's image of NGC 3521 was selected as the backdrop for the official crew portrait of Expedition 30 to the International Space Station. Incredibly, in 2012, he was selected by Time magazine" as one of "The 25 Most Influential People in Space." Pertinent to this book GaBany has written numerous articles, blogs, and reviews for a variety of popular astronomy magazines such as Sky & Telescope, Universe Today, and Astronomy Now.
