Dear Taichi, Thanks for the 2MASS advice. It killed all candidate counterparts, all five of them! They turned out to be bright 2MASS objects, hidden away on each field image I got my hands on, except that of last night's observation. For inspecting unfiltered observations, it is so necessary to have NIR data. I'll send you the image later.

We would also appreciate in receiving your FITS images (via personal e-mails) for further examination.
