Just enjoy this open star cluster at the center of the Heart Nebula, Melotte 15. Here you can find my favorite kind of stars: massive blue O and B type, according to Annie Jump Canon’s stellar classification. Surrounding this cluster is a good quantity of ionized hydrogen and oxygen. The false color technique I used is known as HOO, that I paired with “normal” RGB stars.
Took this from my roof (not the balcony anymore) in Mexico City. #Astrodon#astrophotography#space#astronomy#nightsky
