The Dumbbell Nebula (M27)

Lying in the constellation of Vulpecula, M27, also known as the Dumbbell Nebula is a planetary nebula that lies about 1,360 light years away. It was formed by the ejection of matter from a dying star. This was the first planetary nebula discovered by Charles Messier in 1764.

This is a difficult subject to image from Sydney. Imaging was done between 20 and 33 degrees altitude. Seeing and transparency were consequently less than optimal. Even so, the faint extension of nebulosity is visible.

This is a 11 hr LHaRGB (180, 210, 90, 90, 90) image. Lum subs were 15 mins, Ha subs were 30 mins unbinned.
FOV is 36.1 x 23.8 arcmins @ 1.05 arcsec/pixel.
