The HH objects in the NGC1999 region
Just south (to the right) of the great Orion Nebula lies the small reflection nebula NGC1999 surrounded by strings of Herbig Haro (HH) Objects. This view shows a bright Orion Nebula region and also the very faint dusty NGC1999 region. High Dynamic Range (HDR) techniques have been used to compress the dynamic range. 3 stacks made with 30, 120 and 600 second exposures (488 in total) with a total integration time of 24.6 hours. The stacks have been combined using HDRCombination in Pixinsight and further processsed with HDRMultiscaletransform and other processing steps.
