Stacking Moon images
1

I haven't had much luck with AutoStakkert. I got a decent result once, but mostly it fails completely, or draws a bunch of vertical lines through the image.

(So if someone has a clear write-up on how to use it, I'd be interested.)

But I have this program for focus-stacking - Helicon Focus (NFI). It's intuitive, has only a few user-settable parameters, and lets you quickly go through the image set and look at changes.

It doesn't average the images, but it does choose the 'sharpest' bits from each image to make the composite., Compare this result below - left column is 8 images, focus-stacked. Top is straight out of Helicon Focus, bottom is same image sharpened with Topaz Sharpen AI (again, NFI).

The right side is a single image, SOOC (top) and sharpened (bottom).

Focus-stacking is clearly better than a single image. Because it doesn't average, it's of little use when you have 100 noisy images, but at 1250 mm FL f/10, noise is not an issue.

These shots were taken in the twilight on Jan 10th, hence the blue sky.
