The illuminator (L810 IRS) is located at the position predicted by Scarrott et al. (1991) from analysis of their optical polarimetry. This source is very red (J-K about 3.9) and bright (mK = 10.7), and has an estimated bolometric luminosity of 890 solar luminosities. A NIR nebula was found which extends 20 arcsec symmetrically to the north and to the south of L810 IRS, exhibiting an hourglass shape. Both the morphology and the orientation of the NIR nebula are in good agreement with the morphology and orientation of the high-velocity molecular outflow associated with L810. Finally, we found a NIR jetlike structure whose axis is collinear with L810 IRS. Together, these findings indicate that L810 IRS is likely to be a deeply embedded, very active intermediate-mass young stellar object within the L810 cloud.
