Summer Trip in Kyoto 2017

The summer will be over soon, but the "Summer Trip in Kyoto 2017" will continue till the end of September.
One of the themes of Summer Trip in Kyoto 2017 is "花山天文台" ("Kazan Temmon-dai"). It is an observatory attached to the Graduate School of Science, Kyoto University.
There is a 45cm-diameter reflective telescope in the observatory, and it was in the largest class at that time.
Although it is not so far from Kyoto City, the light is blocked and the place was suitable for astronomical observation. What a nice environment it was!
