This
is a small animation that shows the stitching process. I have re-sampled
the full size image (12x22 inch @ 127.5 pixels per cm) down to one or reasonable
size for downloading (2 x 4 inches @ 60 pixels per cm). All
together over 50 MX-5C images were stitched together to make the final
image. I used Photoshop for the stitching process. Each individual
MX-5C image was loaded as a layer into the Photoshop image. The image
was positioned to match lunar features. Each image was then adjusted
for color balance and contrast to get a good match. For me it seems
impossible to get a perfect match. At f30 and with the poor seeing
conditions present when I took the images I discovered that overlapping
areas showed the lunar features to be slightly different in size in two
adjacent images. Color synthesis and contrast also varies slightly
from image to image. Finally, at f30 it is very easy to miss a small
section of the moon.
As you watch the animation you will notice that irregular shapes are covered as the individual images are displayed. This is cause by the images overlapping. In each case I stitched in a full MX-5C image. Some of the images of the terminator and were also nearly black. This makes the animation look a little jumpy. |
