He was sorting through images from the giant Robert C.

      The object appears to be PSC 54309-1029-1340.

      http://cmarchesin.blogspot.com/2009_09_01_archive.html

      RA 10h29m21.7181
      Declination -13 40' 46.6315"

      In Hydra, about halfway between Lambda and Nu Hydrae, not far from the border with Sextans.

      14 Virgo 36 (2000).
