IC1396 is a large area of glowing hydrogen gas mixed with dark dust clouds. It is a stellar nursery that holds many young nascent stars. This mixture of gas, dust and young stars is responsible for many interesting shapes in IC1396. Most notable of them is "Elephant trunk nebula" (VdB142). Gas in the nebula is energized by the bright, bluish central star visible in the image. The prominent star at top is Mu Cephei, also known as the Garnet Star. Mu Cephei is a very luminous red supergiant, one of the largest and brightest stars in the entire Milky Way galaxy. IC1396 is one of the largest emission nebula complexes visible to us with diameter of several hundred light years. IC1396 is 3000 ly distant.
