Now its time to choose which frame from the video file we want to use as
a reference. All the other images will be compared and aligned using the
reference-image. To find a good candidate use the slider on the lower part
of the screen. Just select the slider and step through the images to find an
image that looks high in contrast and sharpness.
Alternatively, you can check the Show frame list box in the lower left corner
and scroll through each frame individually.

Once the alignment frame has been selected, you need to set the size of the
alignment box. Ideally this box will contain either the whole object you have
imaged or a bright, high contrast feature. You can set this box to a square of
32, 64, 128 or 256 pixels in size. Select a size and move your cursor over
the image. For this example choose 128 and move the square around one
of the major craters and press the LEFT mouse button. RegiStax will now take
you to the alignment page.
