Managed to get a halfway decent Lovejoy image. This was with 2.3 and older PhD and SBIG API as I have not been able to get PhD to do anything but crash with the newer versions (see thread here and PhD forum for that).
Cycle thru events and delays were helpful in putting enough time between exposures to make rejection work pretty well and still keep timing consistent enough to use PI comet script.
Lovejoy from 1-13-15.
