  Sure, just wanted to answer the question. I forgot my :-). I think the four 
question marks tipped us off.

  Good grief guys my last post was tongue firmly between cheek and gum OK?  :-) 
I was just playing with the way Gene wrote that which appeared to be saying 
that "you have (at least) 2514 objects to choose from"! So I followed a line of 
absurdity.   The only question is which list of 400 is the right list of 400.  
And it is just an interesting question for me to find out the history of when 
and why ngc 1750 got the boot in favor of ngc 7814.  Its sort of like finding 
out Pluto isn't a planet anymore and wondering why.

    Not quite so sinister. Of the Herschels, only the 400 on the "H400" you 
already observed are excluded. See directions on SAC website for 'listing of 
the lists' you exclude from your '1000 Other Objects'.

    Interesting.  If that's true I was done a long time ago!  I have logged 
over 100 additional Herschel objects beyond the 380 list objects I currently 
have in my H-400 "list" log as I am also working on the "1000 Objects Not 
Included On Any Other List" uh .. list :-)   I feel bad for the folks that 
struggled for years to get the last few "list" objects when they most certainly 
observed many additional "non-list" Herschel objects over the course of 
observing the "list" objects.  

    But then this leads to another more sinister situation . . .  If the 
Herschel 400 "list" is really any 400 objects from the 2514 "Herschel" objects, 
then is the full 2514 "Herschel" objects list a "list" whereby now my quest for 
the "1000 Objects Not Included on Any Other List" list has to be objects 
exclusive of the entire 2514 "Herschel List" list????
