Representing the heart of the Scorpion in the constellation of Scorpius, the 1.07 magnitude bright M class star Antares blazes in a full rich orange/yellow coloration seen clearly here. Surrounding this stellar gem, the field is awash with a tawny yellow nebulosity, one of the rarest examples of its class in the sky. This reflection nebula IC4606 shines by the reflected light of Antares, and is thus one of the very few yellow reflection in the entire sky. Completing the perfect composition of this field is the dim globular cluster NGC6144. While much fainter at 9th magnitude than the nearby M4 which is just out of the field to the right (West), this 8 arc minute denizen of the outer hub of the Milky Way shines with stars ranging from the orange supergiants at magnitude 13.4 to dim outer blue members at 16.5 magnitude.

Surprisingly there are three 16th magnitude galaxies in this field as well. All are quite reddened by the local Milky Way dust in this region and very dim indeed.
