    I should have been more clear -- you guys are just too sharp!
    The picture was not stacked -- it was a composite, meaning I actually
    stacked them to get the proper registration between frames, but then I cut
    out closely around each J002E3 image overlayed that at 100% opacity to the
    1st image.  So the relative brightnesses are held approximately correct.
    I didn't state this in the e-mail, but we did visually see the object
    through the 16" scope at over 350x.  Previous experience has shown this
    scope to go to 16.5 to 16.7 mag on nights of similar transperancy.  Not real
    scientific, but a good guesstimate.  I did not have time to check "Selected
    Areas" (SAs) for a firm magnitude fix.
    Hope you all enoyed the image.
