NGC/IC Project Restoration Effort

===== NGC 4315 may be one of the two 13th magnitude stars south of NGC 4316. Tempel mentioned the object in his descriptive note that accompanies his micrometric position for NGC 4316 in his fifth paper including new nebulae. In that list, he places N4315 at 2 seconds preceding and 1.5 arcmin south of NGC 4316 -- there isn't anything there. The brighter star is at the required declination offset, but its RA is about 3 seconds larger than N4316's. This would require that Tempel made a mistake in the sign of his RA offset. This isn't unknown -- see NGC 4186 for another example. The fainter star is another candidate. The RA offset is in the right direction (it is 3 seconds preceding the RA of the galaxy), however, it is nearly 3 arcmin south of N4316, not 1.5 as Tempel made it. So, I feel that this is less likely to be his object (though it is the one that I chose the first time I went over the field without Tempel's paper at hand). In either case, Tempel has mistaken other stars near other galaxies as nebulous (see e.g. N577, N4322, N4327, and N4768/9), so having one near N4316 is no surprise.
