I have been trying for a long time to get a reasonable image of Mons Rumker to add to my lunar dome images. See https://roslistonastronomy.uk/more-lunar-dome-spotting-from-the-window-sill-25-07-2018
Rumker, being so close to the limb, is very tricky to get the terminator lighting and libration state right. Here is another go tonight. Slightly better than the last effort above, I fancy, but still not wonderful.
