Perhaps I was a lunar cartographer in a previous life as I always desired to create a series of lunar maps for my own use, at the telescope. The criteria:
a) The view had to somewhat match what I saw at low magnification with either my 4' refractors or my 11" Celestron.
b) The maps would emphasize the features along the terminator; a new map for every couple of days to match the changing terminator line.
c) I wanted to use my own photographs as the basis for the maps, and I'd like to scan these maps into my iPad for ease of use outside.
I wish I could say that I memorized all the features labeled here, but the actual number was around 33%. Charles and Maurice's, "21st Century Atlas of the Moon" quickly filled in the holes. I was so absorbed in labeling the lunar features that I forgot I had dinner cooking in the oven. A smokey mess. Perhaps I really was a lunar cartographer in a previous life.
