Photographed When Sky Was Still Blue

But post-processing blackened the sky:
ISO 100, 1/90th second, prime focus (2000mm, f4.5).

Amazingly this was done without an clock drive.  The Moon is bright enough to take OK pictures at prime focus without.  The ones taken with eyepiece projection were not good because of long exposure requirements..  An equatorial platform is on my purchase list.
