How did I do this??

Hi Charles
For what it's worth, I recall how I did this 14 years ago. 
First, I need to say the arc of the path is incorrect. By doing what you did the moon will track a straight line. I did not know that at the time and made an arced path. Ooops.    

I recall getting very cold over several hours and tracking this partial eclipse from start to finish. The photos were taken in the park across the road and I'd go out for a few minutes at a time. I took photos from close the same spot each series. 

How did I make the poster? I selected the images from start to end that I wanted in the poster. I created a new black background image. 

Each moon image was captured (probably with the circular marquee tool), copied and dropped in sequence onto the black background. Positioning was technical...eyeballed. 

A 36-inch poster of this is till hanging in my office.

I did this in about 2 minutes after I downloaded three of your photos. (I think the RULES forbid this without your explicit permission. Oh well.)  
I set the three images into one frame. Moons 2 and 3 above moon 1 (at the lower left.) 
In image 3 (right), I used the circular marquee tool and roughly selected the moon with some black around the moon. Then I inversed the selection so all but the moon was active (marching ants) and hit <ctrl><X> which deleted most of the image except the moon. Only the moon selection was left. 
Then I selected the layer with moon 2 and repeated the process.
Then flattened.   



The three moon layers.

Clive,

Thank you for doing this!!  What I do not remember doing is HOW to put the 5 images into one frame one image at a time to be able to erase the black area above the previous moon image area?

This is how I created the round selections (based on my very first reply) ... make sense? 

Now that a number of solutions have been posted - Let me kindly remind everyone that the originator has not given permission to edit his images.

Clive,

When I did this back in 2012, I do remember I had to do each individual image separately before doing the next image.

I would put down the first two images laying the second image on top and erasing the black area on the second image above where the moon was on number 1. 
Then I would put #3 on top of #1 and #2 erasing on #3 the area where the moons were on #1 and #2.
Next I would lay #4 on top of #1, #2, and #3 erasing the black area on #4 where the moon was on #1, #2, and #3
Next I would lay #5 on top of #1, #2, #3 and #4 erasing the black area on #5 where the moon was on #1, #2, #3 and #4

Now I was done.

I just now tried to move with the move tool #2 on top of #1 but do not know what I am supposed to move.  Am I supposed to move the layer?  Am I supposed to move the actual picture?
