Masked the moon in Lightroom and was able to increase the exposure enough to bring out earthshine. Also reduced highlights and used noise reduction and chromatic aberration filter in Lightroom.

This was taken at 2pm Central time on April 8th, midway through the 4:10 totality we had in Jackson, Missouri. I used a full frame DSLR and an 800mm lens on a tracking mount. Exposure was f5.6, 1/10s, ISO 100. The original image had no detail for the moon, but when I masked the moon in Lightroom and dialed up the exposure for just that part of the image, lo and behold it was there! But that came at the expense of the prominences, which got reduced to pink spots when I adjusted for chromatic aberration.
