ISS and Venus 2020-04-06 Expedition to Matsudaira, Hitachi-Ota City, where the west sky is clearly visible. The view is wonderful to the low sky. At around 17:37, the ISS (International Spacecraft) appears at the lower right of Venus. I was able to observe.
The mirror was removed from the cylinder by cleaning the self-made 45cm reflector and changing the focus position. I can work alone, but with the help of the star friend, it went smoothly! Thank you.

M46 and NGC2438 are located in the winter Milky Way in Pup, but they are quite low and cannot be seen unless the transparency is good. Tonight’s NGC2438 (planetary nebula), which had good transparency, was found to be pink around the circumference by visual observation at 45 ° (180x). Seeing conition was poor.
