Corwin's Notes

===== NGC 4418 = NGC 4355, which see. N4418 itself has notes in the GC and NGC. There is enough slop in the original position from WH, and enough of a difference between his description and JH's, that JH was not convinced of the identity between his nebula and his father's. In the event, he sorted it out correctly, and Dreyer -- citing additional observations by Lord Rosse and d'Arrest -- confirmed the identity. The NGC 4355 label comes from an observation by David Todd. See the brief discussion under that number, and under NGC 3604, for additional identification adventures in Todd's list.

Steve's Notes

===== NGC 4418 17.5" (3/24/90): fairly faint, small, oval SW-NE, broad concentration. A mag 15 star is just off the SW end 0.9' from center.
