To be honest with you............. I don't recall if I did or not. I've
been looking at the moon for about 43 years and I know it so well at this
point that 'most' of the time I don't really have a need to look at the many
maps that I have all that much.

I was an airbrush illustrator for the USGS for many years and I spent so
much time looking at the moon under different illumination that I just
automatically (mentally) switch views in my head. I can even switch sun
dirrection in my head and have an accurate idea as to what a feature should
look like. Sounds kinda' wierd I guess, but I think it happens to anything
that you spend so much time looking at.

I can tell you that when I switch from a reflector to refractor to
binoculars that it does take me a minute or 2 to reorient myself to the
view.

It just takes lots of time and practice to learn how to do this stuff
automatically and I don't really have any great "Secrets" as to how to do
it. Just spend as much time looking a the real thing and practice using any
lunar maps you can get your hands on.

Good luck and clear skies,
