Sadr is really powerful. In the wide-band dataset, it shines across half of the FOV. The natural palette of the Sadr Region is fascinating with strong dark structures. The narrowband data set collection is still ongoing. Not even Chroma 3nm narrowband filters could handle the bright star. H-alpha, Sulphur-II, and Oxygen-III filters all have halos around Sadr.
About the color of Sadr, it should be “… Sadr is a supergiant star of the spectral type F8 Iab, appearing yellow-white in color…“. Confirmed by the Photometry-based Color Calibration process.
Just love the colors and the boldness, the narrowband version can wait.
