Near the Equator, October's Full Moon is not called the Hunter's Moon. I call it the Prey's Moon because they can easily see the hunter coming.
The Moon fits very comfortably in my eyepiece, meaning it's close to Apogee (it's farthest distance from Earth).
When the Moon is near Apogee, there is little libration (wobbling) in longitude. Grimaldi and Mare Crisium are great reference points to judge this! Note that both are approximately the same distance from their respective limb. There are times when Grimaldi is almost touching the limb (and Mare Crisium is farther away). And vice versa.
I don't think that anyone reads these comments, but I'm bored today.
