Re: [APML] OT: 240 Galaxies in 3 square degrees of Virgo

Jerry,

That's simply amazing to see so many galaxies in one view.  I'm looking 
forward to trying a DSLR with my scopes.  You show what's possible.  BTW, do 
you know what is causing the elongated stars in the upper left?  With the 
short exposures it shouldn't be FR nor ADR.

Thanks,
Don
