Observing Notes

Harold Corwin

IC 757 = NGC 4068. Bigourdan misread his micrometer so that his position angle is 180 degrees out -- his "new" object is southeast of his comparison star, not northwest. Curiously, he made the same mistake on two objects -- the star that he mistook for NGC 4068 as well as his "nova" -- on two nights. His observations on a third night were interrupted by a storm. While he was preparing the manuscript of his big table for publication, he noticed the mistaken position angles and commented that the observations as recorded in his log book would be impossible at the declination of the objects.

Once the correction is made, his position ends up within a few arcsec of a star superposed on NGC 4068, and his description ("Uncertain traces of nebulosity to one side of a * 12: the nebulosity follows this star.").

This same star marks the position given for the galaxy in several more recent lists, too. The center of the outer isophotes of the low-surface-brightness dwarf galaxy is about 10 arcsec northeast of the star. A few arcsec further on is a faint knot or, perhaps, the nucleus.
