Hi Bryan,
Regarding your first post, the images do not need to be in order on
your hard drive, but it's best if they are in order once loaded into
the image stack to reduce image-to-image shift in the case of
imperfect tracking and guiding. If your tracking and guiding is
good, the time ordering is less important. There are various
settings in import image sequence to accomplish the ordering, but if
those do not work and you need the time ordering for whatever
reason, you'll need to somehow manually rename the files so that
they are ordered in sequence after being read into the image stack.
Regarding "when I load as virtual stack and play through the images
to the post flip image it will jump back to the first image when I
plate solve the first flip image", I'm not 100% sure what you are
describing, but it is possible that the Astrometry Setup panel
option "Process Stack" is enabled and might be causing the return to
image slice 1. In that case, plate-solves will always start at the
"Start Slice" specified. To plate solve the specific image currently
displayed in the image stack, disable the "Process Stack" option.
Regarding "When I plate solve a new file WCS is created in the
pipeline out file . . . what do I do with that?", assuming you are
running photometry on the images in the pipelineout folder, that's
where you'd want the WCS information. Assuming you already have the
stack open, you wouldn't need to reload the stack since the new info
is also added to the respective image in image stack as well.

Update
I believe the centroid error was a guiding problem after the flip
still hung up on plate solve with astrometry.net on the first
image and first image after flip.

When I plate solve a new file WCS is created in the pipeline out
file . . . what do I do with that?
