IC 1396 - The Elephant's Trunk


This curling, meandering trail of dust and gas in Cepheus is part of a much larger nebula complex containing both emission and dark nebulae.


The above image is a closeup of the larger image below.





Both images were composed of 26, 300-second images taken on September 14, for a total exposure time of 130 minutes.

NGC 891

This galaxy, seen edge-on in the constellation Andromeda, is estimated to be 30 million light years distant.

This image was composed from seven, 300-second images.

NGC 6946

This image captures the galaxy NGC 6946 and the open cluster NGC 6939, visible in the same starfield in the constellation Cepheus. The galaxy lies 22 million light years away and is occasionally called the "Fireworks Galaxy" because astronomers have detected no less than nine supernova explosions inside it during the past century. The cluster is about 5,800 light years distant.


This image comprises 28, 300-second images, totaling two hours and ten minutes exposure time.
