 This is an object in near the Zone of Avoidance in the Milkyway which is filled with dark dust which not only obscures, but highly reddens distant celestial objects. In this extreme case, a very distant globular cluster on the far side of our galaxy is turned almost a deep red color because of this. Palomar 2 is 2.2 arcminutes in size, and 13 magnitude total. Its brightest stars, many seen here are 19th magnitude because of the extinction. Obviously the B - V is off the charts! There are a few other object that are similar, NGC6380 in Scorpius is also an extreme case of a obscured globular, its orange too. Maffei I in Cassiopeia is a very nearby Local Group galaxy that has been dimmed to near infrared only visibility.
