Corwin's Notes

===== NGC 575 = IC 1710. The 2 degree error in declination is one of the few errors that can be traced to Dreyer himself. Entering this object in his 1878 GC Supplement, he miscopied the correct "69" (degrees of NPD) as "67" (It is also possible that the typesetter made a typographical error. If so, Dreyer did not catch it during proofreading.) He later transferred this exactly to the NGC, so it too has the incorrect degree of NPD. When the correction is made, the galaxy turns out to be the same as IC 1710, found and measured by Javelle. Had the NGC the correct position, Javelle no doubt would have not included the galaxy as a discovery of his own. Dreyer, of course, transcribed the position correctly the second time around. The equality was first noticed by Reinmuth, and mentioned by him in "Die Herschel Nebel" of 1926.

Steve's Notes

===== NGC 575 17.5" (11/30/91): faint, fairly small, round, 1.0' diameter, low almost even surface brightness, broad mild concentration, edges fade into background.
