Description

Here the Helix is shown to emphasize the OIII emission. The OIII data was aggressively stretched and reveals an interesting radial spoke pattern due to those lovely "cometary knots". The OIII data was then overlayed on an RGB layer. Finally, some of the brighter stars were overlayed with additional RGB data.
