Description

I was surprised at the photo.  Due to tracking problems I only had 35 usable subs.  The larger nebula on the right is the Lagoon Nebula (NGC 6523).  It is an emission nebula getting its color from ionized hydrogen.  It is 6000 light-years distant and 110 light-years by 50 light-years across.  The smaller nebula on the left is the Trifid Nebula (NGC 6514).  It is 4200 light-years distant.  It is a combination  of red emmision light from ionized hydrogen gas and blue light from reflected starlight off of fine dust.  They are not associated and are only appear close due to our line of sight.
