Download Full Set of  Printable Maps of M1.

A set of 10  Reference Line Maps, star charts and DSS photos of Supernova Remnant  M1, the Crab Nebula.  These maps works well with red dot finders and green laser pointers.  The Reference Line Method method adapts well to both binoculars and telescopes.

How to Use Reference Line Maps to locate deep sky objects.

Observer Notes:

1. M1 can be difficult in any but the best conditions.  If conditions are good enough to allow location of both reference lines, M1 will be easy.
2. Distinctive serrated outline and filaments will only be visible with large telescopes, but irregular outline is observable with many medium-sized scopes under good viewing conditions.
3. Messier:  “Nebulosity along the southern horn of Taurus.  It contains no star; it is a whitish light, elongated like the flame of a taper, discovered while observing the comet of 1758.”
