Christmas in Tarantula -- NGC2100_Hubble_Palette

This is a photo for the Hidden Treasures competition from ESO. I searched the ESO archives and found a dataset that included the standard filters used in the Hubble Palette of SII red, Ha blue, and OIII Green. The original data was collected in 1996.


I assigned the colors based on the Hubble Palette, and only did minor processing to remove some bad streaks and speckles. There are four layers, Luminosity, SII, Ha, OIII.


The Open Cluster NGC2100 (RA 05 42 09 DEC -69 12 43) is located a degree and a half away from the Tarantula Nebula and is often shown in wide field images of the nebula. Its beauty is often hidden because the Tarantula nebula dominates the exposure time calculations.


I have not seen a photo in the ESO archives like this one centered on NGC2100 and including the nebulosity around the cluster. The dominance of red and green remind me of Christmas and the bright stars in the cluster look like a wonderful ball of Christmas lights.


I hope you like it! If so, send me to Chile!
