Sh2-132 Nebula in HST palette

Sharpless 2-132 is a very faint emission type nebula on the Cepheus/Lacerta border. It lies at a degree southeast of Epsilon Cep, and has a size of about 40 arc minutes. The large but dim emission nebula Sh 2-132 in Cepheus lies 10,370 light-years away and spans another 272 light-years across.

The star at the center of the image below is the very luminous SAO 34301 (HD 211853, mag 8.99), perhaps more commonly known as WR 153, which along with another O-type star (mag 8.5) are primarily responsible for the excitation and ionization of the hydrogen gas in the area and which represents a relatively rare example of a Wolf-Rayet nebula.

NGC 7635 - Bubble Nebula in HST palette

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 Friedrich Wilhelm Herschel. The star SAO 20575 or BD+602522 is thought to have a mass of 10-40 Solar masses.

NGC 7380 - Wizard Nebula in HST palette

NGC 7380 is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142).
Known as the Wizard Nebula, this object is a reasonably large nebula located in Cepheus.

NGC 7380 is located in the constellation Cepheus about 7,000 light-years from Earth within the Milky Way Galaxy. The star cluster is embedded in a nebula, which spans some 110 light-years. The stars of NGC 7380 have emerged from this star-forming region in the last 5 million years or so, making it a relatively young cluster.

IC 410 - Tadpoles Nebula & NGC 1893 Star Cluster in Ha



A faint, dusty rose of the northern sky, emission nebula IC 410 lies about 12,000 light-years away in the constellation Auriga. The cloud of glowing hydrogen gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893.

Formed in the interstellar cloud a mere 4 million years ago, bright cluster stars are seen just below the prominent dark dust cloud near picture center. Notable near the 7 o'clock position in this wide, detailed view are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation, these cosmic tadpole shapes are about 10 light-years long.
