coma cluster - annotated drawing

Notes:
This drawing was made while observing the Coma Cluster region under excellent sky conditions in Negev desert (Israel), while 13.5th to 13.8th magnitude galaxies (in zenith) could be easily picked by my 250mm Newtonian. The sketch is panoramic, and doesn't represent a specific eyepiece field of view.
