Horsehead and Flame Nebula
The Horsehead Nebula known as Barnard 33, is a small dark nebula of non-luminous gas obscuring the light coming from behind, the moderately bright nebula IC 434 discovered by William Herschel (1786).
The Flame Nebula (NGC 2024 or Sh2-277) is an emission nebula about 900 - 1500 light-years away.
NGC 2023 is an emission and reflection nebula discovered also by William Herschel (1785). It is one of the largest of its kind, with a size of 10 × 10 arcminutes.
The bright star Alnitak (ζ Ori), shines energetic ultraviolet light into the Flame and this knocks electrons away from the great clouds of hydrogen gas that reside there.
Sigma Orionis (σ Ori) is a multiple star system consisting of the brightest members of a young open cluster.

NGC 7635, The Bubble Nebula
NGC 7635, also called the Bubble Nebula, Sharpless 162, or Caldwell 11, is a H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, the 15 ± 5 M☉ SAO 20575 (BD+60 2522). The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. It was discovered in 1787 by William Herschel. The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.

M16, The Eagle Nebula
M16 (IC4703, NGC 6611)
Emission Nebula with Open Star Cluster in Serpens (Cauda), distance: 7000 ly, app mag: 6.4, app size: 7 arcmin
Right Ascension 18 : 18.8 (h:m) ; Declination -13 : 47 (deg:m)
Cluster M16 (NGC 6611) discovered by Philippe Loys de Chéseaux in 1745-6. Nebula M16 (IC 4703) discovered by Charles Messier in 1764.
Lying in the constellation Serpens, close to the borders to Scutum and Sagittarius, and in the next inner spiral arm of the Milky Way galaxy from us (the Sagittarius or Sagittarius-Carina Arm) a great cloud of interstellar gas and dust has entered a vivid process of star formation. Open star cluster M16 has formed from this great gaseous and dusty cloud, the diffuse Eagle Nebula IC 4703, which is now caused to shine by emission light, excited by the high-energy radiation of its massive hot, young stars. It is actually still in the process of forming new stars.

Open cluster at Scorpion's Tail is known since the early ages. Ptolemaeus (AD130) described it as a "nebula following the sting of Scorpius". Giovanni Batista Hodierna noted 30 stars counted during an observation in 1654.
1764 Charles Messier descibed M7 as a "comet-like object" in his catalogue.

Orion's Sword (NGC 1976, NGC 1977, NGC 1981)
Orion includes the prominent asterism known as the Belt of Orion: three bright stars (Alnitak, Mintaka, Alnilam) in a row.
Descending from the 'belt' is a smaller line of stars (one of which is in fact not a star but the Orion Nebula), known as the hunter's 'sword'.
