The Moon's terminator is a fascinating sight through all telescopes. Here, along the lunar sunset/sunrise line, lighting can strike familiar lunar features in very unusual ways, transforming them in ways that go unsuspected when the Sun rides high overhead.

Thanks, Mike.  I've seen the thread, but never your Quincunx.  Named for five dots arranged in a cross, with four of them forming a square or rectangle and a fifth at its center.  My new word of the day.  Now, to work that into a conversation!

Quincunx would probably only come into conversation if you play dice!  The five on a die is a quincunx.

Phil,

 

Since reading this article, I'd been anticipating observing these lunar features.  Last night (early 1/14/18 UT) it was clear in the Las Vegas area and I saw the U, V, and X in 60 and 80mm refractors, as well as shooting them with a video camera through a C14.  It was a lot of fun to see them and not worry about dark adaptation and incidental lights from surrounding houses.  The dynamic nature of the view was also interesting to watch as the sun slowly illuminated the features.

 

The Moon was getting too low to see X2 but I look forward to seeing that, too, in the future.

 

Jay

Jay,
 
That's great!  Glad you had a chance to catch the view.  Unfortunately, the Moon had set here on the east coast by the time they all came into view, so I missed them.  In fact, looking at the rest of the year, I don't I'll get a chance to see them, except possibly in daylight, until Dec 14.  It's on my calendar, but my long-range forecast is for clouds.  wink.gif

Here's a cropped image that I took that shows the Quincunx.
