This captivating deep-space image spans a vast cosmic expanse from the Andromeda Galaxy (M31) to the smaller yet equally enchanting Triangulum Galaxy (M33). This astronomical composition is a mesmerizing blend of multi-spectrum imagery, seamlessly harmonizing hydrogen-alpha (Ha) and doubly ionized oxygen (OIII) emissions with luminance (L), red (R), green (G), and blue (B) channels. In this breathtaking capture, the fiery tendrils of Ha and the ethereal glow of OIII emissions intertwine with the intricate details of stars and dust, creating a celestial astro-photo that not only reveals the grandeur of these neighboring galaxies but also provides a glimpse into the intricate astrophysical processes shaping the universe.

I share with you my last take, it is an area that contains several dark nebulae, LDN1158, LDN1157, LDN1148 and LDN1155 among others, an object also called the Gyulbudaghian nebula, named after the Armenian astronomer Armen Gyuldubaghian who discovered it in 1977.
