R. Jay GaBany
Robert Jay GaBany (born September 17, 1954 in Charleston, West Virginia) is an American amateur astronomer and astrophotographer who is also known for his work with an international team of astrophysicists led by (Dr. David Martínez-Delgado ) (Max Planck Institute for Astronomy). GaBany helped pioneer the use of modest size telescopes and off the shelf CCD-cameras to produce long exposure images that revealed ancient galactic merger remnants in the form of star streams surrounding nearby galaxies that were previously undetected or suspected.

Using a half-meter telescope at the remote ( Black Bird Observatory ), GaBany has been one of the world's leading amateur astrophotographers for the past decade. In recent years, GaBany has devoted hundreds of hours to work with a team of astronomers led by Martínez-Delgado of the Max Planck Institute for Astronomy in Germany to produce ultra-deep CCD images of galaxies far beyond our Local Group.
GaBany's images have revealed faint tidal streams and rings in the outer halos of large spiral galaxies, indicative of recent and ongoing gravitational interactions with dwarf satellite galaxies. These images are helping scientists better understand how large galaxies such as our own Milky Way are built up through the collisions and mergers of many smaller galaxies.
Observing under very dark skies, and using very sensitive cameras, long exposure times, and advanced imaging and processing techniques, GaBany has managed to capture details not seen in professional images. Papers based on GaBany's images have been published in leading scientific journals such as the Astrophysical Journal, the Astronomical Journal, and Astronomy & Astrophysics, with GaBany listed as a coauthor.
