Well done! Folk might think it is the easiest thing to take a picture of the crescent moon, looking just like it does with the eye, but it is far from easy. I'm very impressed!
I would love to have made this capture, well done.
I’ve learned a lot since I knew it all.

It is a little tricky. My experience in solar imaging helped. In solar imaging you take an exposure of the solar surface at one exposure and another (second) picture of the filaments/proms at a more sensitive exposure - which is the equivalent to deep sky imaging. Then you combine these 2 images to get the great images you see at times on the solar imaging forum.
In the case of the moon earth shine image, I took one exposure of the crescent at ISO 100 with a 1/125 second exposure(6 images combined/stacked in Sequator). For the dark shadowed part it was ISO 100 at 2 seconds exposure (6 images combined/stacked in Sequator). It was then fairly straight forward to combine the 2 images to get the final result I posted.
Bottom line to remember is the image I posted was not a single image taken with my Sony A7. I also believe many images posted here have some sort of jumping through hoops like this. It is certainly true for those solar images. You can easily tell the single exposure images - at least I think I can
Nicely done; you nailed that! I like your process to get that too
I'll have to remember this post if I one day get an HA scope...
Thanks for the info and great final pic!
All the best,
Mark

Hi Greg. A very nice lunar image revealing the Earth shine, especially on the flickr site. Thanks for sharing the view with us on here Greg and keep up the great work.
