This lovely pair lie just out of frame from NGC346. The Hubble colours certainly accentuate the O3 in NGC371 but also, albeit green as Kermit, the extent of Ha surrounding them both. 371 is about 7.5' x 7.5'.
These are from the EdgeHD14" with ATIK11002M at F11 but I cheated here and Binned x3 to get an image scale close to the magic number of 1.5 arcsec/pixel.
