First Quarter, Hipparchus, Montes Apenninus

The Moon was spectacular tonight.
Lot's of stuff to see.
It's the first quarter so officially a half Moon:



I may have posted a half Moon before, but if you look closely, the Moon is showing more of it's East side. It's also tilted something crazy.
More mountains:



Montes Apennines is a range about 600km long with peak of 5km. Montes Caucasus is a continuation of the Apennines about 520km long with peaks of of 6km. That's almost 20,000ft tall.
Here's some craters we haven't visited:



The two prominent walled plains in the center are Hipparchus(top,150km) and Albategnius(bottom,136km). If you look closely at Albategnius, you can see a central peak of sorts and a smaller crater called Klein which is about 44km across.
Albategnius by the way, was an Arabian prince and astronomer.
It was nice and clear for the most part so I swung the telescope to the East into the constellation Hercules.
Hercules is pretty easy to identify for it sits below Bootes, which is found by following the handle of Ursa Major(the Big Dipper).
In the keystone of Hercules is Messier object called M13. Charles Messier cataloged all sorts of strange things like comets and nebulae way back in the olden days.
M13 was part of his list:



It's that puffy looking thing in the center. Actually that's pretty close to what I see too.
M13 is a cluster of a couple hundred thousand stars. My telescope is too small to resolve any stars, but trust me, they are there:



That's what it looks like though a ginormous telescope but you should still be able to find it with binoculars.
This is good for if I can get M13, I can probably get M31, which is the Andromeda Galaxy.
We'll see.
Andromeda by the way, can sometimes be seen with your nekkid eyeball.
Moon factoid:
Observers of the Moon have recorded so called 'transient lunar phenomena'(TLPs) which include color variation, changes in brightness, obscurities, and gaseous emissions.
