Description

NGC 1999 ( the Keyhole Nebula ) is a challenge to process with all the activity going on in this area ( not to mention satellite trails ).  Original data was reprocessed without the stars to concentrate on the nebulosity and to take advantage of the great AI plug-ins for PS CC.  Stars were added as a final touch.  Taken with the Stellarvue SVX 180mm f/7 with a ZWO 6200MM and Chroma filters.  RGB + H-a.
