My own try on the impressive HST Tarantula Treasury Project data.
Cropped from mosaics F658N and F555W (see Data Source link above), which were mapped to R and B channels (G channel is synthetic , 40% F658N + 60% F555W), also applying a slight hue cosmetic correction to redden the warm colors. Also applied HDR Wavelet Transform and Local Histogram Equalization to improve contrast on nebulosity.
F658N: 658.394nm, FWHM=7.2nm ([N II] 658.4nm & H-a 656.3nm)
F555W: 539.104nm, FHWM=122.511nm (Green)
Many stars showed large, disturbing artifacts (blooming on the F555W data, and black pixels) and were manually corrected one by one with Photoshop, for cosmetic purposes.
