Thank you Jack. I do push myself hard, but there is a lot of great company here on the forum and I certainly don't want to bring the value of the neighborhood down.

When you are looking at the moon focus stacking still helps as its such a large area of different focal lengths. It may be a flat slab of cheese to some but in reality it is a round orb that gravitates around our little world .

OK my friend, I'm going to say your still drinking a few on this one.
Distance to the moon is 238,857 miles (384,400 km).
Diameter of the moon is 2159 miles (3474km) and we only see half of it so that means only 1079.5 miles (1737 km) would actually be focus stackable.
Here is the problem. Using an American football field as a reference, it measures out at 300 feet (91.44 meters), we would be trying to focus stack a 32 inch ball (80 cm) with only 16 inches (40 cm.) of one side being focus stackable. That doesn't even touch on the atmosphere issues, or the fact the optics would fall off at a far greater rate over a quarter million miles than just the 300 (91.44 m) feet of the football field. At any aperture, at this distance, your depth of field is greater than the radius of the moon you would try and focus stack.
Back to you my friend, your thoughts on this?

Yeah just a few
Why is it then that you will get a sharper shot if you focus on the outer edge of the moon? Is it because its better contrast and allows better focal accuracy?
PS I think I need to try and focus stack the moon
and the sun lol. Been awhile since I brought out my bader solar film.

The sun is very dull through my bader film and H-Alpha filter

Actually I have used focus stacking on the moon before. It does work but not for the same reason as a normal focus stacking photo. Normally when we shoot the moon we don't quite get the focus quite the same each time. It will vary just a bit. using focus stacking will just clean it up a little. The time I did it I just hand held it and put it on continuous and fired off several shots.
Day 295, 2013 - Lost Puppy
I went out for a picture at night to see what I can find because the darkness gives you such a different perspective. By day, I saw this ratty old toy left behind and weather is taking its toll. However, at night this forgotten toy had such a sad story to tell it screamed out at me and I had to photograph it.
Walking through the park in the middle of the night you see something. Moving closer you see it. There, in the single spot of light under a tree lays this tattered little puppy. Most assuredly it must have been terrified before falling asleep as it had lost the little girl that owned it. Feeling a little safer in the dark of the night it laid under the one spot of light to wait. From its fur, matted and discolored, you can see it had been on its own for a long time and without love. The cold air must have gotten to the pup as it curled up ever so tightly to stay warm. Leaves falling as they may upon the ground as the little puppy waited out the dreaded long cold scary night in hopes that his little girl would find him and take him back home to the foot of her bed.

Great commentary!

At first glance I thought of a palm tree on an island. Then realized what it was. Great photo.

But your daughter is only three inches tall so this would be a tree to her. Remember the mushrooms?
Great commentary but it also made me a little sad. I felt like, "I hope the little girl finds this poor, lost puppy."
That is just cool! Very nice viewpoint!
