About 9 hours on NGC 300 (6 hours luminance) taken at a dark sky site in the southern Flinders ranges in SA last weekend. Cloud + wind meant that this was the only data/object I managed to gather
Taken with a ZWO ASI1600MM-C on a GSO RC8 + Astro-Physics Mach1.
Higher res version available on Astrobin
here.
Comments/suggestions welcome as always.
