Terry,

An explanation of why we see two tails (one a dust tail and one an ion 
tail) is visually given at: 
http://www.sidleach.com/comet_c2007_n3_lulin_antitail.htm.

I'm not entirely sure ... but looking at the rough general area of the 
sky where Comet Lulin was last Saturday, and matching up some of the 
stars, I would say the bright star is beta Virginis, or Zavijava.  And I 
think the faint galaxy above the comet when it starts is NGC 4073 ... 
although there are a lot of galaxies in that area.
