Description In spite of its large 10x8 arcmin size, this nice spiral galaxy is not mentioned in Hartung's "Astronomical Objects for Southern Telescopes", possibly because of its low surface brightness.  Turbulent atmospheric conditions made imaging and processing a challenge and caused an overall softness to the final result.
