The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion’s Belt in the constellation of Orion, and is known as the middle “star” in the “sword” of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with apparent magnitude 4.0. [wikipedia]

The Pelican Nebula (also known as IC 5070) is an H II region associated with the North America Nebula in the constellation Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name. [wikipedia]

The Cygnus Loop is a large supernova remnant (SNR) in the constellation Cygnus. Radio, infrared, and X-ray images reveal the complete loop. The visual portion of the Cygnus Loop is known as the Veil Nebula, also called the Cirrus Nebula or the Filamentary Nebula. Several components have separate names and identifiers, including the “Western Veil” or “Witch’s Broom”, the “Eastern Veil”, and Pickering’s Triangle. [wikipedia]

IC 405 (also known as the Flaming Star Nebula, SH 2-229, or Caldwell 31) is an emission and reflection nebula in the constellation Auriga north of the celestial equator. [wikipedia]

NGC 1931, the Fly Nebula (top) is an emission and reflection nebula, and has been referred to as a miniature version of the Orion Nebula, as it shares some of the same characteristics. There is a smaller version of M42’s “Trapezium” in the hot, young star cluster in the centre of the emission nebula. It is about 3 arcmins in size and is 4000 – 7000 light years from Earth.

IC 417, the Spider Nebula (center) is an emission nebula and star forming region. The nebula contains a young open cluster (Stock 8), and is energized by its hot, massive blue stars which are still embedded in glowing hydrogen gas. The bluish clouds of gas at the top of the image are locations of new star formation. [astro.nightsky.at]

The Whirlpool Galaxy, also known as Messier 51a (M51a) or NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus. It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. [wikipedia]

12P/Pons–Brooks is a periodic comet with an orbital period of 71 years. The comet nucleus is estimated to be around 30 km in diameter. It will reach “perihelion” when it is closest to the earth at a distance of approximately 232 million km. [wikipedia]

Messier 13 or M13 (also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules, the Hercules Globular Cluster, or the Great Hercules Cluster), is a globular cluster of several hundred thousand stars in the constellation of Hercules. Messier 13 may be visible to the naked eye with averted vision on dark nights. [wikipedia]

The Rosette Nebula (also known as Caldwell 49) is an H II region located near one end of a giant molecular cloud in the Monoceros region of the Milky Way Galaxy. [wikipedia]

The Horsehead Nebula (also known as Barnard 33 or B33) is a small dark nebula in the constellation Orion. The nebula is located just to the south of Alnitak, the easternmost star of Orion’s Belt, and is part of the much larger Orion molecular cloud complex. The Flame Nebula, designated as NGC 2024 and Sh2-277, is an emission nebula in the constellation Orion in the lower left of the photo. [wikipedia]

Simeis 147, also known as the Spaghetti Nebula, SNR G180.0-01.7 or Sharpless 2-240, is a supernova remnant (SNR) in the Milky Way, straddling the border between the constellations Auriga and Taurus. [wikipedia]

NGC 2264 is the location where the Cone Nebula, the Stellar Snowflake Cluster and the Christmas Tree Cluster have formed in this emission nebula located in the constellation Monoceros. [wikipedia]

The California Nebula (NGC 1499/Sh2-220) is an emission nebula located in the constellation Perseus. Its name comes from its resemblance to the outline of the US State of California in long exposure photographs. [wikipedia]

NGC 2174 (also known as Monkey Head Nebula) is an H II emission nebula located in the constellation Orion and is associated with the open star cluster NGC 2175

Soul Nebula is an emission nebula located in Cassiopeia. Several small open clusters are embedded in the nebula. [wikipedia]

The Heart Nebula (also known as the Running dog nebula, IC 1805, Sharpless 2-190) is an emission nebula, 7500 light years away from Earth and located in the Perseus Arm of the Galaxy in the constellation Cassiopeia.

IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a galactic supernova remnant (SNR) in the constellation Gemini. [wikipedia]

Messier 108 also known as NGC 3556, nicknamed the Surfboard Galaxy) is a barred spiral galaxy about 28 million light-years away from Earth in the northern constellation Ursa Major. It was discovered by Pierre Méchain in 1781 or 1782. From the Earth, this galaxy is seen almost edge-on. [wikipedia]

The HII region Sh 2-261 is often called Lower’s nebula because it appears on a photographic plate taken by the father-and-son team of Harold and Charles Lower in 1939. [wikipedia]

The Tadpole Nebula (IC 410) is an H II region located approximately 12,400 light-years away in the northern constellation Auriga. It is associated with the young open cluster NGC 1893. [constellation guide]
