M57 - The Ring Nebula - 160929

This image of Messier 57, the Ring Nebula, is a stack of 16 ten-minute frames taken with the Celestron Nightscape camera on the Celestron 11" Edge HD Deluxe CPC, stacked in DSS and processed in Photoshop.

M57 (NGC 6720) is a relatively large and bright planetary nebula located just south of the star Vega in the constellation of Lyra. It is easily detectable with a good telescope even in moderately light polluted skies. This glowing ring is an expanding wave front of ionized gas expelled from the remains of a red giant star, now visible as a white dwarf in the middle of the ring.

You can also see the faint face-on barred spiral galaxy of IC 1296, which I hadn't noticed in previous attempts at capturing M57. This one is too faint to see with a typical telescope in any sort of light pollution. There's also another tiny galaxy just to the lower left of that in a line out from M57.
