Barred Spiral Galaxy IC 1158:
Quote from the Dreyer's Index Catalog to the NGC:
Most extremely faint, pretty large, and irregularly round.
This face-on barred spiral galaxy is in the constellation of Serpens. Its low surface brightness ( 14th magnitude ) makes it difficult to observe except in large telescopes. A rough distance estimate for IC 1158 is 100 million light years, and at that distance, the diameter would be 74,000 light years.
