I was looking back on the images I had taken last week, as we are having another spell of cloudy skies lately, and was able to do a little experimenting with Registax 6, working on a couple of individual craters. I processed 2 different areas tonight, the first was in the area near Crater Janssen. Basically, I let Registax resize when I stacked, then saved the finished image and cropped it to create the illusion of a higher resolution than it seemed. I then resized the image back down 50% in the resize window and saved that as a comparison.
Here are the 2 images, the first is the normal 640X480 image:
Next is the 2X resize and cropped area around Crater Janssen.
This was an experiment, taken with some pretty good raw footage taken on 6/6/11. This feature might come in handy to zoom in on specific areas of the moon.
