Corwin's Notes

===== NGC 475 = IC 97. Marth discovered three galaxies here (NGC 469, 471, and 475), and his positions are pretty good. Two of his positions got changed for the NGC, however -- for the worse. Dreyer credits Peters for N475 as well as Marth, and it is apparently Peters's position which throws off the NGC. Marth's original position is within a minute of Bigourdan's measured place for IC 97, so the identity is certain. The object which Bigourdan calls N475 is a star near the incorrect NGC position.

Steve's Notes

===== NGC 475 17.5" (10/4/97): threshold object that was barely glimpsed on a couple of occasions at 280x with averted vision using a GSC finder chart to pinpoint the location. Visible less than 10% of time and would not have detected at all without first knowing precise position. Appeared ~10" diameter but much too faint for any details. Located 4.5' N of NGC 471 and 7' E of NGC 469.
