And here is the second image. The commentary is the same.
This is a very dense star-field on the edge of the Lagoon Nebula. The source of these data are the Mikulski Archive for Space Telescopes Portal. The interesting part of this is that it is false color. That is, there were several filter sets available, but not the normal RGB ones we use down here on earth. For this image I assigned the filters as follows: 960 nm = Red, 752 nm = Green and 480 nm = Blue. Interestingly, it almost looks like a natural color image.
If you are interested, this data sets and many, many others can be found at the following URL (
https://mast.stsci.edu/portal/Mashup/Clients/Mast/Portal.html). I searched "Lagoon Nebula" and selected the four overlapping panels that bracketed the heart of the Lagoon Nebula. After processing each panel, I made a mosaic. This image is just a small portion of that mosaic. Other portions of that image are to follow.
If you want to try processing some of this data, have fun. :-)
