Image data aquired from my back garden in Macclesfield, UK.

The famous Rosette Nebula, shown here as a narrow-band composition in Hubble palette (HST). I started to aquire data for this image at the end of December 2014 but only now (Feb 2015) have I had opportunity to finish it! The image consists of 10 x 1200sec subs each channel of OxygenIII, H-alpha and SulphurII, so a total of 10hrs exposure. I love the detail in the gas and dust shell surrounding the central cluster of young bright stars, those dark knots are slightly denser pockets of material seen in silouette.
