NGC253

Here's another shot of NGC253, a large and beautiful galaxy in Sculptor. This represents a 2 shot mosaic, my first attempt at doing so. The image lacks good signal to noise, due to clouds that cut the early evening session short (it cleared later on). Only 32 minutes were taken on each half at f/6. This shot was taken at the Chiefland Star Party, 2003.
