Description

Inspired by @David Elmore's beautiful image of the Methuselah Nebula, I tried to pick up as much OIII signal as possible, with a little less exposure time in Halpha and SII. Since there is almost no nebulosity in the SII channel, the SII are not used in composing the image.

The image confirms that there is an extended shell around Methuselah emitting mostly in the OIII line.

The image was processed in Siril with pixelmath, denoising and GHS - and post-processed in Rawtherapee with tone mapping.

The pixelmath parameters of the final image version C were simply as follows:
  • Red: H
  • Green: O
  • Blue: O
