Emission nebulosities and star forming regions in Orion
Uploaded 3/5/22

 
This
            amazing part of the sky contains a brilliant but small blue reflection
            nebula - NGC1999 with its tiny T shaped internal dark Bok globule,
            several star forming Herbig Haro objects including the Waterfall
            nebula, all in a background nebulosity that fills the entire
            field. Below I also include a photo key for identification.
