Description

The original set of data was used for one of the featured images to celebrate Hubble 28th Anniversary. The close-up shot of the nursery heart was just jaw-dropping.

Target: The Vast Stellar Nursery of Lagoon Nebula (M8)

Stretched and leveled the raw data in Fits Liberator before getting it right. Converted FITS files to TIFF with Fits Liberator and PixelMath'ed them together in PixInsight. Cosmetic touch-ups done in Photoshop. Final process completed in Lightroom.

ACS/WFC: F658N
ACS/WFC: F656N
ACS/WFC: F547M
ACS/WFC: F502N

Color Mapping (PixelMath):
Red - f658n*0.9
Green - f656n*0.6 + f502n*0.25
Blue - f502n*0.7 + f656n*0.22

The F547M image has couple of huge halos and light spikes. Tried a few times to fix the cosmetic issues without good result. So I gave up on the F547M. That's the reason for lacking the blue region in final image. But it's still stunning enough.
