Ran the AVI through virtual dub and converted to greyscale. In Registax, processed in Black and White, which speeded it up quite a bit. The average pixel error was 6, with a maximum of 8, when the air is steady, those numbers are 2 and 5. Tried drizzling at 50% x3. A gaussian blur to take away the drizzle blocks, then lots of sharpening. Tightened up the levels in Photoshop. It’s contrasty, but the smallest craters visible on the floor of Clavius are less than 4 miles across.
Here’s Clavius and company October 9/10. Shot at f/9.
Clavius same night shot at f/15. Conditions were not up to this magnification.
