Is the cluster in the same orientation as the nebula? Thanks for looking, Aldo Gabriela Mistral Nebula with face mask and cluster NGC 3293.png h...

Hi all, Coloring was made taking in consideration real emissions of Hydrogen alfa (Ha) and Oxigen III (OIII) as captured from my observatory and combined as R=Ha, G=OIII, B=OIII. Regarding the Homunculus, the external nebula was considered a source of Ha and consequently prevalent in red color (http...

Hi all, images in RGB resulted from combination of Ha with OIII (HOO).
Thanks for looking!

Picture 1 was taken before sunset and shows a group of dark clouds at low altitude over Mar del Plata city. Sun was close to reach the west horizon. The da...
