M27 - The Dumbell Nebula

Planetary Nebula in Vulpecula

Uploaded 6/29/2001

This huge spherical planetary nebula rides high in the evening skies during late summer evenings, and presents a perfectly sized CCD target. OIII and Ha nebulosities combine to form a sharp edged spherical shell, surrounding the blue central star. Also known as NGC6853, this 7.6 magnitude object is one of the brightest of its class in the sky, only outdone by a small handful of smaller objects. M27 is 6.7 minutes in size officially, however it is much larger if you count the outer ears seen here.
