Description

This planetary nebula was captured with two narrowband filters, Hydrogen-alpha (Ha) and Oxygen-III (OIII). I also took short exposures with Red, Green and Blue filters to capture the natural color of the stars. This is a false color image that combines Ha in the red channel, and O-III in the green and blue channels. The star color image was blended with the false color image to produce the final result. The faint white dwarf can be seen in the center of the dumbbell. This image also reveals the faint outer shell of expanding gas. The remaining issue with image processing is that there are dark halos around stars in within the nebula.
