The Colourful Nebulas Around Antares by Alan Dyer
Via Flickr:
The colourful region around Antares in Scorpius, the yellow star at centre. To the right is the globular cluster Messier 4. Above right of Antares is the smaller globular NGC 6144. Above are the nebulas associated with Rho Ophiuchi. The area is filled with reflection (yellow and blue) and emission nebulas (red and pink). The field simulates a binocular field…This is a stack of 5 x 2-minute exposures with the 200mm lens at f/2.8 and filter-modified Canon 5D MkII at ISO 1600.
