If you open SDSS image and click zoom (+) 3 times, one can suspect the
blue star hidden behind the brighter red dwarf at 4 o'clock (WSW)
direction:
http://skyserver.sdss3.org/dr8/en/tools/chart/chart.asp?ra=269.85084854&dec=25.34254633

So, there may actually be three stars where SDSS is seeing two! Then
WZ Sge scenario becomes not so impossible as I originally thought.

Also, keep in mind that the robotic photometry of MASTER unfiltered
images with the red zero point is often too bright by ~0.5m. If you
observe MASTER OT J175924.12+252031.7 in V band, I would expect ~13.2
magnitude rather than 12.7.
