I was out this morning as dawn was approaching and decided to capture these 18 captures for a stitch.  Each is 30% of 750 frames.  The sky background gave me a bit of trouble and you can see a bit of blue along the terminator of a couple of the frames taken towards the end of the session.

Very nicely done!  Especially with the challenges at that time of day.

Looked at that situation few hours earlier.

I take the liberty to pull out a quite distinct feature, imaged well here, that catches the eye, for me in my 107/600 at decent seeing.

N of Aristarchus, there is the craterlet Nielsen, and from there up to the Rümker mountains / dome, a quite straight dorsa. That could be mistaken for a rille or a rupes. Terrain E of the dorsa is considerably lower, some 100m+ maybe, enabling that outlining shadow. See profile.

 

Was a bit more distinct in the hours earlier, with a more outlined shadow line, I found.

 

The crater rim of Wargentin in full light was another feature in that phase.

 

regards

A better comparison should be made with the individual full-chip images.
