Elephant Trunk: IC1396A
Very clear night last night here. This is a detail from an earlier wider field image "The Misty Clover Cluster". I used my larger telescope to focus on the "Elephant Trunk" part of it.
About the target:
(from cosgrovescosmos.com): "IC 1396 is a large circular region of glowing gas and dust in the constellation of Cepheus and is located about 2400 light-years from Earth. Measuring approximately 100 light-years across, this region is energized by a bluish central multiple star called HD 206267.
The ionized gas glows bright while dark dust concentration in the area can also be seen.
The Elephants Trunk, IC 1396A, is one feature that stands out prominently in images taken of the area. Pressure from bright stars in the core blows dust from that area leaving behind a darker region at the center of the nebula while compressing dust around the edges, which drives new star formation. As a result, up to 250 young stars- all less than 100,000 years old, have been detected in infrared images taken of the Trunk region in 2003. The Trunk itself is about 20 light-years long."
