M27

Updated: 6.27.04

M27, the Dumbell Nebula in Vulpecula, is a beautifully large and bright planetary that rivals the Ring in name recognition. This particular image used an (L+R)RGB combine to bring out a bit more of the internal structure. The image was taken at f/10, but reduced to 80%, so effectively appears as an f/8 image scale. Only 36 minutes were shot at this slow speed due to the impending sunrise (last frame at 5:32AM). The shot was taken at Chiefland, Florida during the last new moon event.
