NGC 2244 Rosette Nebula (version 4: full narrowband)

This rather colourful scene is the Rosette Nebula in the Hubble Palette....Sulphur II glows Red; Hydrogen alpha glows Green: and Oxygen III glows blue. I only managed 6x10 mins of the sulphur data, so the red is a little grainy. Nevertheless, it shows a huge amount of detail for an image taken from our light-ridden and murky English skies. I particularly like the way the narrowband increases contrast to reveal the more delicate structures of the nebula. I have added in some RGB data for the star colours. The SII data was taken in 10 minute subs, unguided, which is a tribute to the tracking accuracy of the Paramont ME2 with Tpoint and Protrack activated (250 point model)
