Notes: NGC 5774 and 5775 (the brighter of the two) are the two larger, brighter galaxies to the northeast (upper left). Other interesting galaxies in this field are IC 1067 (2.1' x 1.7', mag 13.0p, Cl: SB(s)b) and IC 1066 (1.4' x 0.8', mag 14.1p, Cl: S?) to the southwest (lower right), and the little 'ring' galaxy to their northwest designated CGCG 48-40 (PGC 53126, 0.8' x 0.8', mag 15.7, Cl: --).

Contemporary Visual Observation(s) for NGC 5774
NGC 5774 = UGC 09576 = MCG +01-38-013 = CGCG 048-057 = Ho 685b = LGG 387-003 = 
PGC 53231

V = 12.1;  Size 3.0x2.5;  SB = 14.2;  PA = 145d

17.5": fairly faint, moderately large, round, fairly low surface brightness, 
gradually brighter but no well-defined core.  A mag 14 star is off the NE edge 
1.4' from center.  Forms a pair with N5775 4.5' SE.

Historical Research Notes / Correction for NGC 5774
NGC 5744.  There are two candidates for this, each roughly the same distance 
from the nominal position.  Since the Leander McCormick RAs are usually too 
far east, my inclination is to take the SBc galaxy to the west as the one that 
Ormond Stone saw.  This also has the slight additional advantage of being at 
exactly the declination as that recorded by Stone.

However, the galaxy to the east has a higher surface brightness (it is a 
compact and slightly distorted S0), and seems that it would be more likely to
be seen during a sweep.  It is, however, further off in both RA and Dec, so I
am less inclined, on purely positional grounds, to take it as Stone's object.

So, given the skimpiness of Stone's description (m = 15.5, D = 0.2 arcmin, and
the note "neb?") along with the usual poor RA, I'm simply listing both objects
and letting you choose whichever one you think is correct.  If you could drop
me a line letting me know which one you can see most easily, I'd appreciate 
it.  This clearly needs some visual work. - Dr. Harold G. Corwin, Jr.
Contemporary Visual Observation(s) for NGC 5775

V = 11.4;  Size 4.2x1.0;  SB = 12.8;  PA = 146d

17.5": fairly bright, moderately large, elongated 3:1 NW-SE, weakly concentrated 
to a large elongated brighter central region.  A mag 13 star is just NE of the 
core 0.9' from center.  Forms a pair with N5774 4.5' NW.
