Here is our image, combined work, from many nights in july 2024. SH2-115 is an emission nebula located in the constellation Cygnus, an area rich in nebulae and H II regions. This nebula shines intensely with reddish tones, a result of hydrogen gas ionization by the young, hot stars within it. The structure of SH2-115 is complex, with dark filaments of interstellar dust contrasting against the surrounding nebula's glow. Abell 71 is an intriguing object that has been classified both as a planetary nebula, generating debates among astronomers about its true nature. It features a bright ring structure, with a defined ring of ionized gas standing out against the dark background of space. This object, with a characteristic blue color due to the emission of doubly ionized oxygen, is surrounded by more diffuse nebulosity, suggesting the interaction of the gas with the surrounding interstellar medium. Abell 71 is a fascinating challenge for astrophotography due to its low surface brightness.
