Here is a before and after sharpening. Did I sharpen too much?

You might try selective sharpening so you don't emphasize any over-sharpening halo and green fringing on the lower half of the Moon.

No. Looks better sharpened.

Thank you!

I do not know how to do selective sharpening.... what do you mean by the halo and green fringing? I do not see anything green?

I use Photoshop Elements 2020

I do thank you for your suggestion!

If you look at this composite I made of your sharpened and unsharpened versions, you should see the oversharpened edge on the bottom and left side of the moon along with a faint green color turn off and on every second. By selective sharpening, you should be able to use something like a lasso tool in Elements to just select the parts of the moon you want to sharpen so that when you apply sharpening, the edges won't get overdone.

I hope that makes sense.

If I understand you correct you took my before and after photo and blended them together. What did that show you?

I am sorry but I still do not see anything oversharpened and I still do not see any faint green color turning off and on. Should I see this within Elements just after doing the unsharp mask? I just now took my original file and did the unsharp mask again, using the same numbers as before... I wrote down the numbers... but I still do not see any faint green color flashing.

I do understand using a lasso tool in Elements, but I have to re-learn how to do that because it has been a spell since I have done that.

Do not get me wrong, I am not mad or upset you made a composite, I am fine that you did that. Do you have any idea why I am not seeing what you are seeing?

Charles, I see a greenish highlight flash on and off. It's a thin line at the very edge of the combined moon image and only the left and bottom parts of that edge.

OK... if I stare at Navydoc's image of my photo now I do see it. I have stop and stare. I went back to MY photo and stare at that image, I still do not see the flashing....

Why would there be flashing on his composite of my image but not on my image?

Do YOU see any flashing in my photo above?

Sorry for any confusion. I created an animated gif so that you could see the difference between the unsharp version and the sharpened version by turning off the sharpened layer once a second.

I thought I would show you the edge of the moon with what I thought looked to be over sharpened by making an animated gif so you could see the difference between your unsharpened and sharpened versions.

My suggestion was just to use one of the selection tools in Photoshop Elements to select everything but the lower and left edge of the moon so that that area would not get over sharpened when you applied sharpening to the rest of the image.

The green is very subtle so I wouldn't worry about it.

Here's a 400% enlargement to show the green.

No. The flashing happens because navydoc superimposed one of your versions (sharpened and not sharpened) on the other. He made the sharpened version blink on and off. Neither of the original images flashes by itself.
