Here is a wide field shot with some familiar galaxies and some not so familiar ones. It is also a part of the sky with several bright stars in a small area. I think I am practicing some wide field stuff for the summer Milky Way.
I left the background kind of high so some of the fainter objects are visible. The edge stars were a bit affected by the short focal length so I merged a layer that used the star repair plugin for Photoshop. There is a full resolution version link for those of you who want to see the gory details.
Image and exposure / processing details are here:
