OBJECT DESCRIPTION (*)

NGC 6188 is one of the most beautiful emission nebula of the sky. The region gathers young blue stars, hot red gas and cool dark dust.  Is the home of a group of young stars which forms the open cluster NGC 6193. Its stars are so bright that reflects interstellar dust forming a diffuse blue glow which is nearly visible in the photograph.

The object was too low in the horizon and this photograph is in fact a test image to see what the object responds to the SXVF H9 and the C8. Not much exposure but is quite a promising target for the next weeks.
