Description

This is a rarely imaged nebula and I have wanted to make a deep image after an initial look-see exploratory image I took three years ago. Steve was intrigued too by the manifold appearance of the layered hydrogen emission and there is the small Soap Bubble-like PN too. I have a crop to better show its delicate nature.

Of course being located in the Milky Way near Cygnus there is a magnificent starfield that makes for a colourful background - all in all a delight to process.

Abstract from "Planetary Nebulae: Understanding the Physical and Chemical Evolution of Dying Stars" by Ronald Weinberger & Florian Kerber: Planetary nebulae are one of the few classes of celestial objects that are active in every part of the electromagnetic spectrum. These fluorescing and often dusty expanding gaseous envelopes were recently found to be quite complex in their dynamics and morphology, but refined theoretical models can account for these discoveries. Great progress was also made in understanding the mechanisms that shape the nebulae and the spectra of their central stars. In addition, applications for planetary nebulae have been worked out; for example, they have been used as standard candles for long-range distances and as tracers of the enigmatic dark matter (Science 30 May 1997: Vol. 276, Issue 5317, pp. 1382-1386, http://science.sciencemag.org/content/276/5317/1382).
