Visibility IV / V
I was holding a star show for a group of students at Ulvila Observatory. After the star show, I was still left to test my new Hyperion eyepieces. As one of my test subjects, I looked at the Moon, whose phase at the time of observation was about 62%. I was immediately reminded of the possibility of LTP phenomena, so to document the incident, I took pictures of the Moon Mare Imbrium region with the camera of my Sony smartphone directly through the eyepiece using the “digiscoping” method.
However, it is likely that the Sun is shining on the peaks of some of the mountains at the bottom of Mare Imbrium and they appear exceptionally bright due to the contrast. The mountain peaks, glistening from the shade and illuminated by the Sun, automatically compare their pitch black to the night of the Moon on the terminator side, which is why the mountain peaks look so bright.
According to the 4-month map of the Astronomy Enthusiast's Handbook, one of the enlightened mountains would be Pico, according to my interpretation, the other is not named on the map of the above-mentioned book. The picture also shows the craters Archimedes (the largest of the craters), Autolycys (the second largest of the craters) and Aristillus (the smallest of the craters). In Figure 1, the craters form a triangle with Archimedes at the top corner and Autolycus at the bottom left and Aristillus at the bottom right)
