Description

Six panel mosaic of the California Nebula in Ha and SII.

Used Straton to remove the stars from the individual narrow band images and then attempted the "tone mapping" technique to combine the Ha and SII data. Used Ha alone as luminance. Added the stars back at the end of processing.

Still needs a lot of work. The SII mosaic was much less clean than the Ha mosaic, so it took a lot of work to get them combined in a way that didn't degrade the final image compared to the Ha-only mosaic. SII needs more time, but wanted to post something so I can work on some other projects in the meantime.
