I see some galaxies in the M10 image (I counted 26 candidates in the
M12 image when I spent some time looking in detail yesterday), however I
wonder if a factor may not be the 50% increase in exposure time between
M10 and M12. Except for two, none of the galaxies in either image are
particularly bright. The increase from 180 to 270 total minutes, 60 to
90 for luminance, could be significant.
Both great images, either way.
