Mousing off the image reveals a “Hubble Palette” narrowband image, with
Even after 8 hours of Sii data and 7 hours of Oiii, the image was still fairly noisy in those channels, so I replaced the luminance with the Hα image and cranked the color saturation a little. This really tamed the noise while preserving the essence of the tricolor image.
A higher resolution image is also available. North is up.
