Columns from left to right: Z, Y, J, H, and K_s images and rows from top to bottom: those of 2010, 2015, difference, and ratio (range 0…17.5). The crosshair marks the MYSO position. For the upper two rows, the values comprise 98 percentiles, displayed using a linear stretch. At red optical wavelengths (two leftmost columns), the object appears bipolar. Both blobs are probably due to scattering, with the eastern one brighter in Z. Both are offset from the nominal MYSO position and indicated by the red Z contours in Fig. 10. The prompt LE is visible in all five bands. Its large size in the K_s ratio image is due to a smaller number of scatterings compared to the other bands. A common foreground proper motion binary (blue arrow) appears in Z and J next to G323. The FoV amounts to 70″ × 45″.
