This was taken last Friday (March 24, 2023) about one hour after sunset using a Takahashi FC-100DZ and a ZWO ASI183MM Pro camera. The image was created from 256 subs that were each exposed for 250ms and thus it had a total integration time of 64 seconds. The faintest stars that were recorded in the background sky were around magnitude 12 and you can see the brightest (HD18405) at magnitude 7 that is just to the lower left of the moon and only a few minutes from occultation.
Since the moon was moving in respect to the stars I had to combine two different registrations (one on the moon and the other on the stars) so that both the moon and stars were reproduced with as much detail as possible. This is probably the sharpest image of earthshine that I've ever gotten and at the original scale it is possible to see structure in the interior of the crater Aristarchus (the below image is about one quarter of the size of the original).
Image capture using SharpCap Pro, processing with Autostakkert! (registration on the moon), Registax (wavelet sharpening), SiriL (one star registration), PixInsight (histogram and dynamic range adjustments), and Photoshop 2023 (photo composition, tweaks, and photo frame). There are additional details in the image captions (click on the preview to read them).
You can see what the sunlit side of the crescent moon looked like in an earlier post of mine here on CN:
Questions, comments and criticisms (QC&C) welcomed and thanks for visiting.
I uploaded a higher contrast version because the smaller size (from the original) that I posted was lacking in detail. I think the new version looks better.
Also, I thought of another way to blend the stars into the background and by doing that and with some further tweaks to the contrast and lightness of the earthshine I think I can produce an even better version (for posting maybe tomorrow or the next day).
Uploaded new version with improved stars and detail.
