Henize 206 is a region of star formation in the LMC of the approximate scale of Orion. Our Spitzer Space Telescope infrared images and CTIO MCELS optical images show that radiation from young stars has excited strong PAH emission throughout Henize 206, except on the side of the nebula with the prominent young supernova remnant. As is also seen in ERO observations of M81, star formation rates calculated from H\alpha may be biased low by extinction, compared with star formation rates calculated from far infrared emission.
For one of the two highest surface brightness regions of Henize 206, we obtained snapshot exposures with the T-ReCS mid-IR camera on Gemini South to explore the complex structure. A few percent of the total energy from these brightest regions in Henize 206 emanates from infrared peaks of subparsec scale. Their luminosities are equivalent to those of B stars, similar to the excitation agents in Orion.
