The image of SH2 308 shown below belongs among the very best images
of this object (or rather it is the very best image of this object).
It was acquired by the CielAustral group of astro-photographers (Jean Claude
Canonne, Nicolas Outters, Philippe Bernhard, Didier Chaplain and
Laurent Bourgon) with G4-16000 camera on the TEC160 refractor.
Image was combined from relatively short exposure-time exposures
through red, green and blue filters and very long (over 40 hours of
accumulated exposure time) exposures through Hα and OIII narrow-band filters. Total exposure time
was 89 hours.
