NGC 7090

This edge-on spiral galaxy is located in the southern constellation of Indus. It is about 31 million light years from us, and was first observed by John Herschel on the 4th of October 1834.

 

It has an apparent magnitude of 10.51 and an angular extent of 8.15 X 1.63 arcmin. I love looking for all the other objects far off in the distance. The halo reminds me of a fish with the tail at the base flaring out, and the head at the top.
