IC objects IC objects The Eagle Nebula (also known as Messier Object 16, M16 or NGC 6611) is a young open cluster of stars in the constellation Serpens (Cauda). It is associated with a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of current star formation is about 7,000 light years distant. ...more on Wikipedia about "Eagle Nebula"
The Horsehead Nebula (also known as Barnard 33 or IC 434) is a dark nebula in the Orion constellation. The nebula is located just below Alnitak, the easternmost star of Orion's Belt, and is part of the much larger Orion Molecular Cloud Complex. ...more on Wikipedia about "Horsehead Nebula"
Irregular Galaxy IC 10 (or simply IC 10) is an irregular galaxy, a dwarf galaxy, and a starburst galaxy in the Cassiopeia constellation. It was discovered by Lewis Swift in 1889. IC 10 is located approximately 4.2 million light years (24.6 quintillion miles) away from the Milky Way. It is also the closest known starburst galaxy and a member of the Local Group. ...more on Wikipedia about "Irregular Galaxy IC 10"

Open Cluster IC 4665 (or simply IC 4665) is an open cluster in the constellation Ophiuchus. It was discovered by Philippe Loys de Chéseaux in 1745. The cluster began to develop less than 40 million years ago, and lies about 1,400 light years away from Earth. It is easily visible in the smallest of telescopes and also with binoculars. From a sufficiently dark place it is also visible to the naked eye. ...more on Wikipedia about "Open Cluster IC 4665"
Open Cluster IC 4756 (or simply IC 4756) is an open cluster in the Serpens constellation. It is at a distance of about 1,300 light years away from Earth. ...more on Wikipedia about "Open Cluster IC 4756"
Open Cluster M25 (also known as Messier Object 25 or IC 4725) is an open cluster in the constellation Sagittarius. It was discovered by Philippe Loys de Chéseaux in 1745 and included in Charles Messier's list in 1764. ...more on Wikipedia about "Open Cluster M25"

The Sagittarius Star Cloud (also known as Delle Caustiche, Star Cloud M24, IC 4715 or NGC 6603) is a star cloud in the constellation of Sagittarius, approximately 600 light years wide, which was discovered by Charles Messier in 1764. ...more on Wikipedia about "Sagittarius Star Cloud"
The Southern Pleiades (also known as the Theta Carinae Cluster, Open Cluster IC 2602, or IC 2602) is an open cluster in the Carina constellation. It was discovered by Abbe Lacaille in 1751 from South Africa. The cluster is at a distance of about 479 light years away from Earth and can be seen with the naked eye. ...more on Wikipedia about "Southern Pleiades"
The Spirograph Nebula (also known as Planetary Nebula IC 418 or IC 418) is a planetary nebula in the Milky Way Galaxy. It gets its name from its resemblance to drawings from the Spirograph cyclical drawing tool, and shows patterns that are not well understood. Perhaps they are related to chaotic winds from the variable central star, which changes brightness unpredictably in just a few hours. ...more on Wikipedia about "Spirograph Nebula"
The Tarantula Nebula (also known as 30 Doradus, or NGC 2070) is an H II region in the Large Magellanic Cloud. It was originally thought to be a star, but in 1751 Abbe Lacaille recognized its nebular nature. ...more on Wikipedia about "Tarantula Nebula"
The Witch Head Nebula (also known as IC 2118) is named after its shape, as can be seen seen on the right. It is believed to be an ancient supernova remnant or gas cloud illuminated by nearby supergiant Rigel in Orion. It lies in the Eridanus constellation, about 1000 light years from Earth. The nature of the dust particles, reflecting blue light better than red, is a factor in giving the Witch Head its blue color. ...more on Wikipedia about "Witch Head Nebula"
