Both with 8'' F/4.4 newtonian + paracorr + ASI678MC.

The wide one without a barlow, very simple 1000 frame recording with best 100 stacked:

And the closeup of the Mare Humboldtianum, right at the limb. This one is barlowed to ~2350mm focal length:

Seeing was OK, at times even pretty good, but the Moon was at 21 degrees of elevation so the captures were not very sharp most of the time. The closeup is best 1% from 25 000 frames, any more and it gets even softer.
