This file presents the Messier objects in the order of the Marathon Search Sequence given by Don Machholz in his Messier Marathon Observer's Guide.

The Messier Marathon Search Sequence

compiled online by Hartmut Frommert, using work of Don Machholz. Depending on geographic location, it may be impossible to find them all, and may be better to slightly modify this list. In case of doubt consult Don Machholz's book. This list should be good for northern latitudes 20 to 40.
