This is the red image.
This group of stars is a small star forming aggregate lying just south of the L1641N group. V380 Ori, the optically brightest object in this group has been recognized for a long time as a member of the Herbig Ae/Be star population (Herbig 1960), a young intermediate mass star. It is the bright object illuminating the large reflection nebula (NGC 1999). The original H-H objects (Herbig 1951, Haro 1952) are also found in this field. They are the nebulous objects in the lower half of this image. An optical infrared study of this region (Strom et al. 1985) was able to identify the powering source of the outflow, of which HH 1 & 2 are the visible manifestation, as the cm wavelength VLA source discovered by Pravdo et al. (1985). A water maser source, detected by both the VLA and IRAS also lies within this field as do numerous other extremely young objects as shown by the luminosity function derived for the region by Strom, Strom and Merrill in their infrared imaging study of L1641.
This image was made with an optical CCD with a broad band filter centered at a wavelength near 6500 Å. While the images are not exactly aligned, you can easily seee how many fewer stars are visible at this wavelength by tracing the obvious stellar patterns. Nebulosity emitting in the Hydrogen alpha line, such as the knots in HH2, is also enhanced in this image.
You may also see images at other wavelengths by clicking on the colorbar at a point above any of the dashed arrows (which point to other regions of the spectrum at which images are available). The solid arrow shows the spectral region you are seeing now.
