      I lose it after soon after this.

      I can't actually see anything at Rainer's stated x,y's (were they
      512x512?). Regardless, I'm nearly done measuring in HI1B, and A is
      finished. So even if I have to email them from home, I will get these
      out to Brian tonight.

      Cheers,

      Gidday Karl, Rainer et al, I agree with these positions, lost across stars after this. My Ypos = Karl s 1024-ypos, which is +/- a few pixels to close Rainer s

        Gidday Karl, Rainer et al,
         
        I agree with these positions, lost across stars after this.
        My Ypos = Karl's 1024-ypos, which is +/- a few pixels to close Rainer's position.
        We are all looking at the same object.

                I see Mr. Michael Jaeger has joined this forum,  he is most welcome here, as he is a prolific and talented comet imager. Many of the images I  have seen are quite spectacular.
