The Elephant’s Trunk (IC 1396) – Widefield

Overview

A few nights ago I put a pin in a new project of the large emission nebula in the constellation Cepheus, often called the Elephants Trunk or IC 1396. This image was created using five nights of data across three narrowband filters (Hydrogen-alpha, Sulfur-2, and Oxygen-3) and 25.8 hours of integration time.

IC 1396 is a vast emission nebula and star-forming region located in the constellation Cepheus, approximately 2,400 light-years away. Spanning about 100 light-years, this nebula is a mix of glowing gas and dark interstellar dust, making it a stunning sight in astrophotography. At its heart lies the bright star Mu Cephei, which ionizes the surrounding gas, creating the characteristic reddish glow.

A notable feature within IC 1396 is the Elephant’s Trunk Nebula, a dense region of gas and dust where new stars are forming. This region is shaped by stellar winds and radiation from nearby massive stars, highlighting the dynamic processes of stellar birth. Due to its large apparent size, IC 1396 is best observed with wide-field telescopes or photographed using long exposures and narrowband filters. This nebula provides astronomers with valuable insights into star formation and the interplay between young stars and their surrounding environment.
