Corwin's Notes
=====
NGC 7122 is the double star that I've included in the position table. This
was first identified as a "nebulous" star by Edward Cooper in his "Markree
Catalogue" of stars near the ecliptic. Auwers includes it as the 47th object
in his list new nebulae culled from the pre-1860 literature. Reinmuth noted
it as a "* 10.5, eF eS neb or * 15 att np." The northwestern object is
clearly a star on the modern sky surveys, though on the DSS2B plate, its image
is pretty well blended with its brighter neighbor to the southeast. It is
well enough separated on the DSS2IR plate that I've given positions for both
objects. UCAC has also separated the stars, so I've adopted those positions.
