This is a collage of spiral galaxies taken in 2006 through my 4" Takahashi FS102.  These spirals were selected because they are interacting with many neighboring galaxies that either distort their shape, or that induce new star formation in the outer galactic arms.  Due to distortion, some galaxies (like NGC 3718 and the Cocoon Galaxy) have lost their classical spiral structure, whereas others like M51 and M100 have retained their Grand Design spiral shape.    M51 is in the upper left, NGC 3718 is in the upper right, the Cocoon Galaxy is in the lower left, and M100 is in the lower right.  Please click on the individual galaxy links for photographic details.
