Four planets at Dusk

The "once-in-a-lifetime planet alignment",  from yesterday evening.
And technically, it was "once-in-a-lifetime" because the chances of these four planets aligning exactly like this again in my lifetime are very small. 
I was not able to see Mercury, and of course Neptune, with my eyes. A single 1-second image revealed Mercury and a stack of 33 x 1-second exposures revealed Neptune. You might need a computer screen to see them in the image,
It was an amazing evening, again at Bacon's Castle, Surry VA, which has a good view to the western horizon.  It was comfortable outside, and the peepers are already peeping.
