NGC 604 in M33 (October 2016)

Here is a grand nebula in another galaxy.  Galaxy M33 is about 2.5 million light years away, about as far as the Andromeda Galaxy.  That's not very far for a galaxy.  M33 is our near neighbor.  This nebula is a huge cloud of glowing hydrogen from which stars are forming.  In the upper right third of the image you can see stars in a curve of one of M33's spiral arms.  These stars are some of the brightest stars in M33. You are literally seeing here light from individual stars and stellar systems in another galaxy. Other nebulae also dot the landscape.

This image is just 12x600" through the CFF290 Classical Cassegrain at f/7.93, with the SXVF-H9 camera.
