Dardenne Prairie, Missouri

I also collected six hours of Ha exposures but these didnâ€™t add anything to the image I didnâ€™t use them.
Sh2-191 (Maffei 1, LBN 659 and others) is behind the open cluster Czernik 11 on the right side of the image.
Sh2-197 (Maffei 2, UGCA 39, Dwingeloo 136.5-00.3 and others) is the galaxy on the left side of the image
Sh2-195 (LBN 665 and others) is located around the same location as Sh2-197.
All of these are located behind an arm of our galaxy so they are heavily obscured. A good paper on the IC 342 / Maffei Group can be found here – http://iopscience.iop.org/article/10.1086/313255/pdf.
