The Western Veil (also known as Caldwell 34), consisting of NGC 6960 (the "Witch's Broom", [10] Lacework Nebula, [8] "Filamentary Nebula" [10]) near the foreground star 52 Cygni; The Eastern Veil (also known as Caldwell 33 ), whose brightest area is NGC 6992 , trailing off farther south into NGC 6995 (together with NGC 6992 also known as ...
NGC 6960, the Western Veil, is the western part of the remnant, also known as the "Witch's Broom", located at J2000 RA 20 h 45 m 58.1 s Dec +30° 35′ 43″. [3] As the westernmost NGC object in the nebula (first in right ascension), its number is sometimes used as an NGC identifier for the nebula as a whole.

A photo of the Messier 51 galaxy taken on June 3, 1902, at the Yerkes Observatory George Ritchey image of what he called the Great Nebula in Cygnus (In modern times the Veil Nebula); taken with the two-foot reflecting telescope with 3 hours exposure
IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection [2] /emission [3] nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470. [4]
NGC 6946, sometimes referred to as the Fireworks Galaxy, is a face-on intermediate spiral galaxy with a small bright nucleus, whose location in the sky straddles the boundary between the northern constellations of Cepheus and Cygnus.
Photoevaporation is the process where energetic radiation ionises gas and causes it to disperse away from the ionising source. The term is typically used in an astrophysical context where ultraviolet radiation from hot stars acts on clouds of material such as molecular clouds, protoplanetary disks, or planetary atmospheres.
