Moon Mosaic
This was taken with a Nikon D80 and Meade 14" SCT. It's 11 single pictures of different parts of the Moon all stiteched together using Autostitch. I chose just the green layer and converted it to black & white, sharpened and adjusted brightness/contrast, all in GIMP. This results in a 56 Mpixel picture that takes up about 13 MB. I had to crop it a bit and reduce the image quality to get it under the 10 MB limit for Weebly.
This one was made from 8 individual images, all stitched together. This one is backwards from the one above... oops.
