Corwin's Notes
=====
NGC 7433 and NGC 7435 are galaxies close to NGC 7436, the brightest object in
a subgroup of a cluster. All three objects, along with the fainter component
of NGC 7436, are shown in Lord Rosse's sketch of the field. Though the NGC
positions are not too good, the sketch positively identifies the objects that
Dreyer catalogued. Bigourdan's observations of NGC 7433 and NGC 7435, by the
way, refer to stars (see the discussion under CGCG 097-087 in the "notngc"
files), while d'Arrest measured NGC 7435 (not N7433 as noted in the NGC) as
well as N7436.
Steve's Notes
=====
NGC 7433
48" (10/26/16): at 610x; moderately bright, fairly small, elongated 5:2 SW-NE, 35"x14", brighter nucleus. Located 1.5' NW of NGC 7436 in a group. A mag 14.3 star is 0.4' S.
24" (7/20/12): very faint, small, very elongated 3:1 SW-NE, 24"x8". A mag 14.3 star is just 24" S of center. Located in the core of the NGC 7436 group, just 1.5' NW of NGC 7436.
The historical identification of NGC 7433 is ambiguous (see notes), but this galaxy is misidentified as NGC 7431 (which is 2.9' W) in CGCG, UGC, PGC, U2000 and Megastar.
