Corwin's Notes

===== NGC 1777. JH's original description reads, "eF, E, attached to and following a D * (9 = 9m)." However, the double star (a wide one, with 30 arcsecond separation) is actually east of the core of the cluster, not west. The NGC description, however, reads "eF, E, ** 9 att, f", which is correct. This is from the GC which also claims a total of two observations, though only one is given in CGH. Note also that the RA in CGH, GC, and NGC is one minute of time too small. The cluster is far enough south, however, that the correct object is close enough to be unmistakeable, especially given that the wrong position falls into an empty field.

Steve's Notes

===== NGC 1777 30" (10/14/15 - OzSky): fairly bright, fairly small, irregular shape, 45" diameter. Two mag 11.2/11.5 stars = HJ 3722 at 31" separation are superimposed on the east side of the glow! Only a couple of mag 16 stars pop around the edges of the mottled glow. Mag 12.5 and 13 stars lies 2.2' SE and 1.7' NW and a brighter mag 10.6 star is 3.6' N. Located 38' N of mag 5.5 Eta Mensae.
