Steve's Notes

===== NGC 3999 24" (3/22/14): very faint, very small, round, 15" diameter, even surface brightness. Situated 1.4' E of a mag 12 star and 4.5' SSW of mag 8 HD 103913. A string of gaalxies oriented NW to SE begins with NGC 4000, which lies 4.5' N. 17.5" (4/18/98): extremely faint, very small, round, 15" diameter. Requires averted vision and can only hold steadily 2/3 of the time. A mag 12 star is 1.5' preceding. Located 4.6' SSW of mag 7.4 SAO 82077 in the NGC 4005 cluster. The RNGC identification is incorrect.
