M16 and M17 (Very Wide Field)

This image is really a Milky Way shot as there is not much detail in M16 and M17 with an 8 degree FOV. Also, M18, M24, and M25 are in this image as well as a variety of other cataloged objects. Its kind of a dalliance I am doing this summer with wide fields - I promise to get back to more traditional imaging soon. I kept the processing on the bright side to see some of the Milky way features. Image can be seen here:

Hey there Jim. That is a nice "dalliance"! I really like these wide shots that show how things fit together. The dark dusty areas are very cool as well as the nebulous regions. Nicely done!
Cheers,
Tyler
