Darren FlynnM27 - dumbell nebula
This sphere of ionised (electrically excited) gas is expanding at a rate of 31kms per second after the collapse of the parent star about 14,500 years ago. It has collapsed to a white dwarf star whose radiation is illuminating the gas by ionisation.
Our sun will probably follow a similar path in 5 or 6 billion years, since it's not big enough to collapse into a black hole.
M27 dumbell nebula is around 1360 light years away in the constellation Vulpecula (fox). It was the first planetary nebula discovered, by Charles Messier in 1764.

Comet 67P Seen by Kepler
The European Space Agency's Rosetta mission concluded its study of comet 67P/Churyumov-Gerasimenko on Sept. 30, 2016. NASA's planet-hunting Kepler spacecraft observed the comet during the final month of the Rosetta mission, while the comet was not visible from Earth. This ...

Dr NKarShorter night, continuous cloud cover - not much astrophotography opportunity lately. The Great Globular Cluster in the constellation Hercules is now well placed in the evening sky, 20 min total data.
