The nebula is thought to be about 100 light years across and 5,000 light years from our solar system.

This image is a composite from two black and white images taken with the Palomar Observatory's 48-inch (1.2-meter) Samuel Oschin Telescope as a part of the Second Palomar Observatory Sky Survey (POSS II). The images were recorded on two glass photographic plates - one sensitive to red light and the other to blue. The plates were scanned and color combined to produce the image seen here.
