Eagle Nebula by Jeff Baumgardner September 26, 1996 When this image was acquired, the sun was 10 degrees below the horizon (i.e. bright twilight!). The image was captured by Boston University's 20 inch telescope at the McDonald Observatory in Texas, re-imaged from f / 10 to f / 3.3. The exposure time was 100 seconds on a 1kX1k TI215 CCD camera binned to a 512X512 image with 24 micron pixels through a 14 Angstrom H-alpha filter.
