IC1396 – “the Elephant’s Trunk Nebula” is a huge emission nebula in the constellation of Cepheus, about 2500 light years away. It has a huge angular diameter of about 2 x 3 degrees so it requires a wide field telescope/lens to capture it in its entirety.
It is a very popular imaging target both in a wide field setting like this picture and also as close up views of the “trunk” that you can see in the image at the 6 o’clock position.
