Hi Russ,
Thanks for the nice comments. The short answer to your
question is unfortunately no at this time. However, I do plan to
offer this feature in the near term. Do you need a solution right
away or do we have some time? We currently only support TAN and
SIN WCS projections (with or without SIP distortion corrections),
although we will eventually add support for all projections
defined in the FITS WCS spec. Different projections are relatively
easy to add as long as I have some sample images with the
appropriate WCS headers for testing. Could you work with a limited
number of projections initially? If so, which projections would be
required to get started and could you provide a sample image with
each projection? We could do the file exchange outside this forum
if desired.

First...I love this program. For the first time, my
high school astronomy students (in a mac environment where X11 is
not allowed) will be able to do some great image processing.
Here's my difficulty, however. I am trying to develop a lesson
where students take images from a radio telescope at Green Bank
(the 20m) and align them with optical images from optical SKYNET.
All images are in FITS format and have WCS solutions.
Can I use the WCS to align these multi-wavelength images? If so,
how?
