Hello Bill,

I've just downloaded the new version and imported an CCD image (ST-
10ME, from Martin Fiedler, Radebeul, Germany) with WCS (solved
with Astrometrica). This new function is fine.
Some hints for other users: my image was displayed completly white
(contrast 10000 to 10000, background of image is about 18000). The
adjust buttons for brightness and contrast didn't seem to work. Only
after clicking on the upper left corner of the image they did their job.
That's ok, but you have to know it.

Then I realized a serious problem: the image is positioned ok, but
rotated by 180 deg!
Examing the file REALSKY.DAT gives the RA and DE coordinates of
the corners of the image in the following sequence:
1.) upper right, 2.) upper left, 3.) lower right, 4.) lower left

Changing the sequence of coordinates to 4-3-2-1 gives me a correctly
orientated image. Is this a bug? The orientation settings in
Astrometrica are neither flipped horizontal nor vertical.

Clear skies
Bernd
