Nebulosity in Corona Australis (IC 4812, NGC 6726/27 & Barnard 157) and globular cluster NGC 6723;  Digital composite of two one-hour exposures on hypered 120 format Kodak PPF Pro 400 film.  Each negative was scanned at 2000 dpi using a Polaroid Sprintscan 45.  The scanned images were first optimized for brightness and contrast then inverted to a negative image in Photoshop 5.0.   The two negative images were then digitally "stacked" using the FILTER transformation in Picture Window 2.0.  The resulting negative image file was inverted back to a positive in Photoshop and further enhanced to produce the final image.
