Corwin's Notes

===== NGC 4752 may be CGCG 071-058. WH's description "vF, S, E, r" fits very well -- but his position is 38 seconds off in RA, and 15 arcmin off in Dec. Dreyer notes that Bigourdan did not find the galaxy, and gives an additional offset from II 128 = N4689. That leads to a position that is within WH's observational error of the one in his table, so there is apparently no large error in his data collecting and reduction. The fact that his description fits the CGCG galaxy so well, however, suggests that there is an error somewhere in WH's position. But it is not apparent from the information we have on the object, so I've put a question mark on the identity.

Steve's Notes

===== NGC 4752 18" (5/12/07): very faint, very small, elongated 3:2 SW-NE, 0.3'x0.2', visible continuously with averted vision. Located 43' SE of 5.7-magnitude 29 Coma. The NGC identification with this galaxy is very uncertain due to a poor position by William Herschel.
