We show that SIPS J2045-6332, a late M/early L object previously identified as a candidate spectral mix binary, shows an elongated image shape. Using shape measurement techniques originally developed for cosmological weak lensing surveys on VISTA VHS images we show that this likely blended binary has an implied position angle of ~290 degrees East of North with a secondary companion that is likely to be a late L dwarf. This object would be a good follow-up target for high resolution imaging studies
