NGC/IC Project Restoration Effort

===== NGC 5160 is a double star very near d'Arrest's position. It was seen as a double star by Tempel (though he described it as nebulous on two nights) as well as by Bigourdan, who measured its position. His measurement agrees with mine for both stars, and also -- implicitly -- with the GSC position for the northern. Bigourdan also gave good estimates of the relative magnitudes of the stars, as well as their distance (10 arcsec) and position angle (0 degrees; though on the POSS1, the PA is about 7-8 degrees). Furthermore, d'Arrest notes the 12th magnitude star 28.3 seconds following, 1 arcmin north, of his object. That star is just where he says it is.
