Spiral Galaxy in Cepheus

Click on this image to see a full sized image of a LOG scaled image to bring out the dim field nebulosities.

This face on galaxy nebula in Cepheus is in a very dust obscured part of the Milky Way, and therefore is quite yellow in color, with a high B-V index of 1.0. This 11.6 magnitude galaxy is also unsual in that it is located well within the "Zone of Avoidance" for galaxies in the galactic band, and can be seen so well. Much to my surpise, much of the obscuring material was luminous, and when you click on the lower thumbnail, you wll see this is indeed a galaxy behind a significant amount of nebulosity in Cepheus. This is the first case Ive ever photographed with such an obvious luminous cloud in the foreground.

The galaxy is small, at 3.9 x 3.2 mins, and is classed as Sb/SBc type.
