Wow, that's a magnificent image (or two versions of the same image, one with annotations)! I wonder how many hours went into producing it?Hermann von Eiff wrote: ↑Wed Jun 13, 2018 5:48 pm M42 - The Scorpius Constellation

Thank you for that picture, Cristina! NGC 4490 and NGC 4485 are two of my favorite galaxies, because they are so blue. I very much appreciate that your picture underscores how blue they really are (although you also show us that the center of NGC 4490 is in fact yellow, as expected).cfm2004 wrote: ↑Wed Jun 13, 2018 8:24 pm Aprile 2018
