Re: [APML] new image

Dear Brian,

      An excellent image!  It takes no imagination whatsoever to see 
that this H II region is bursting out of its molecular cloud cocoon. 
Please keep up the good work.  Since you mention your location 
without describing your sky background, just how bright is your sky 
background in magnitudes per square arcsecond in B and V?

Paul
