Arata, are you sure those coordinates are correct, I get nothing on the first two, trying for third object. Do you know the epoch (J2000, J2004...)?
Edit: No, nothing. I do get faint blobs though. I can search it on SIMBAD, but that brings up alot. I tried the first on simbad but got nothing.
I searched the third, and got the best one which was this:
Name
distance arcsecs
type
coordinates
[BFS2004] V160
13.33
RR*
00 46 14.30 +40 43 22.7
Sadly, noe came up as galaxies, the one above is an RR Lyrae variable.
