GALLERYS CELESTIAL BAUBLE Kevin Osborn
Sharpless 2-308, also known as the Gourd Nebula, is a
60-light-year-wide bubble blown by a hot stellar wind from
the bright star in the middle. The wind is shaping gas released
thousands of years earlier. Kevin used a Sky-Watcher Esprit
100 ED telescope on a Sky-Watcher EQ6-R Pro mount. The
camera used was a ZWO ASI1600MM Pro with red, green,
blue, H-alpha and OIII filters.
