Hi all,
I imaged Tuttle a few weeks ago. It's not a terribly interesting comet in a particularly boring part of the sky, but we had a window of clear skies in Northern California, it was up, and I had a couple of hours to kill.
I have gotten as far as creating star aligned masters, and a comet aligned stacked master. But when I try to subtract the comet image from the star aligned subs, I can't get it to subtract. I'm wondering if it's something I'm wrong when I try to subtract, or if my data is just bad. To do it, I control click all the comet star aligned files, identify the starting and ending time for the comet x,y coordinates using the first and last sub, select the comet integrated as the operand image, select "image integration", and "comet aligned", and I adjust the "reject low" to just above the comet background. Still I can't get it to work, or at most, only one or two of the subs will reject the comet.
I am wondering if anybody can look at the data set?
Here is the comet integrated master with the stars rejected

I hate it when I don't know why things don't work. I've spent way too much time on this already--you know how it is.
Thanks in advance for any advice.
Stuart
