The IRSA 2MASS image server (http://irsa.ipac.caltech.edu/) also shows this
as a quite extended object aligned NNE-SSW in all three of the J, H and Ks
bands, and which appears thicker at centre... ...3 objects????

The object isn't resolved in the DENIS DCMC catalogue either, where a
further passband magnitude of gunn I = 10.2 is listed.

PS I've cut and pasted a very small postage stamp of the 2MASS J band image
for this object reduced to 256 colours for people not familiar with the
IRSA server.
