Not meant to be a pretty picture but a preliminary task in isolating the OIII and Ha emissions in the Tarantula nebula.

These images will be used as masks to extract the information from the final image.

The first attachment show OIII dominating regions in the Tarantula, the second shows Ha dominating.

Note the dark regions are not nebulae but areas where either the OIII or Ha features have been subtracted.
