As a footnote: I remember my problems with ImageAlign before were caused by the fact that the images were simply too small. So if we make them bigger, it should work better.
bin = Binarize[ ImageAlign[ImageResize[all, Scaled[2]], ImageResize[part, Scaled[2]]]] where 'all' and 'part' are the two images.
and it seems to work.
First[Position[ImageData[bin], 1]] returns row and column:
{187, 175}
