The Sadr Region (also known as IC 1318 or the Gamma Cygni Nebula) is the diffuse emission nebula surrounding Sadr at the center of Cygnus's cross. The Sadr Region is one of the surrounding nebulous regions; others include the Butterfly Nebula and the Crescent Nebula. It contains many dark nebulae in addition to the emission diffuse nebulae.
NGC 6302 (also known as the Bug Nebula, Butterfly Nebula, or Caldwell 69) is a bipolar planetary nebula in the constellation Scorpius.The structure in the nebula is among the most complex ever seen in planetary nebulae.

IRAS 19475+3119 is a protoplanetary nebula in the constellation of Cygnus, 15,000 light-years away. The central star, V2513 Cygni, is an F-type post-AGB star. The brightest portion of the nebula shows a quadrupolar structure, with elongated bipolar lobes, all surrounded by a faint halo.
Messier 29 or M29, also known as NGC 6913 or the Cooling Tower Cluster, is a quite small, bright open cluster of stars just south of the central bright star Gamma Cygni of a northerly zone of the sky, Cygnus. It was discovered by Charles Messier in 1764, and can be seen from Earth by using binoculars.
NGC 2346 is a planetary nebula near the celestial equator in the constellation of Monoceros, [5] less than a degree to the ESE of Delta Monocerotis. [6] It is informally known as the Butterfly Nebula. [3] The nebula is bright and conspicuous with a visual magnitude of 9.6, [3] and has been extensively studied.
From this work Sharpless published his catalog of H II regions in two editions: the first in 1953, with 142 nebula; [3] and the second and final edition in 1959, with 312 nebulae. [ 2 ] [ 4 ] Sharpless coordinates are based on the star catalogs Bonner Durchmusterung (BD) and Cordoba Durchmusterung (CD), but the second release was adjusted to ...
