The deep space object centered in the image above at approximately 60 million light years distant is NGC 7497. Sprinkled throughout the frame are a number of more distant galaxies. Though NGC 7497 is centered, it is not the focus of this image. In the foreground lies a veil of dust known as the Intergalactic Flux Nebula located about 1000 light years just outside of our own Milky Way galaxy.

This image uniquely show the capabilities of a long focal length telescope in conjunction with a large format chip. Total integration needed to bring out the IFN with this f/9 RC and a 16803 chip was 21.9 hours. Acquisition, processing, and copyright Dave Kopacz & Lee Buck.
