Corwin's Notes

===== NGC 4182 may be NGC 4180, or it may simply be a star at Peters's position. That position is 3 degrees south and 17 seconds following NGC 4180. Arguing for the identity is his observation of NGC 4191. Both it and NGC 4180 are about 13th magnitude, and close enough together on the sky that it is difficult to understand how an observer could see one but miss the other. On the other hand, Peters's position for NGC 4191 is only 4 seconds following the true position -- his measured separation for the objects (assuming only a 3 deg error in declination) does not match their separation on the sky. And the star at his quoted position is faint enough that it could have been mistaken for a nebula. In the end, we would need to re-examine Peters's charts to find the objects that he thought were nebulae. Until then, I slightly favor the NGC 4182 = NGC 4180 idea, though not by much.
