After you’ve seen the beautiful Veil Nebula (NGC 6960/92/95) and the popular North America Nebula (NGC 7000), take a look at some of Cygnus’ other striking nebulae. Red emission nebulae, blue reflection nebulae, and the supernova remnants known as planetary nebulae abound in the constellation of the Swan. A clear, moonless night, a moderate-size telescope, and some time are all you’ll need to continue your nebula search.

The Butterfly Nebula (IC 1318)
IC 1318 comprises a large area about 2,100 light-years away. Nebulosity surrounds Cygnus’ central star, Sadr (Gamma [γ] Cygni). The Butterfly is a bright, apparent magnitude 14.9 emission nebula that measures about 240′ across.

The Cocoon Nebula (IC 5146)
IC 5146 is both a blue reflection nebula and a red emission nebula. Hydrogen gas envelops an open star cluster containing several 12th-magnitude stars. The Cocoon, which lies about 4,000 light-years distant, has an apparent magnitude of 7.2 and spans 12′. Find the Cocoon Nebula about 2° below and to the right of magnitude 4.5 star 81 Pi2 [p2] Cygni.

Planetary nebula PK 68-0.1
Peculiar, asymmetric planetary nebula PK 68-0.1, also known as M1-75, consists of two contiguous shells. The nebula is faint at 16th magnitude, and its disk’s diameter is about 10″. Try 140x and a UHD filter to help bring PK 68-0.1 into view. Find it about 14′ north-northeast of the magnitude 6.9 star SAO 69343.

Planetary nebula NGC 6894
NGC 6894, also known as PK 69-2.1, is a faint 14th-magnitude planetary nebula that appears as a pinkish spherical shell surrounding a 17th-magnitude star. The nebula measures about 44″ by 39″ and lies about 4,000 light-years away. To locate NGC 6894, start at magnitude 2.5 star 53 Epsilon [ε] Cygni, star-hop down to NGC 6960 in the Veil Nebula, then scan right about half the distance to the cross’s bright vertical line of stars.

The Tulip Nebula
Sh2-101 is a 9th-magnitude, irregular-shape, bright emission nebula that measures about 16′ by 9′. The Tulip is located some 8,700 light-years away. Look for the Tulip Nebula to the left of 4th-magnitude star 21 Eta [η] Cygni, which lies about 5° beneath and right of magnitude 2.5 star Sadr (Gamma [γ] Cygni).

The Clown Nebula
Sh2-112 is a bright emission nebula about 9′ by 7′ in size. To find the Clown Nebula, look for a small red dot of nebulosity to the right of magnitude 1.5 star Deneb (Alpha [α] Cygni).
