2021-11-29 Mini astronomical observation party
It is an annual astronomical observation party. I changed it the day before due to bad weather forecast on the 30th, so the number of participants decreased, but I managed to enjoy the stars with 45 cm newtonian.
The Orion Nebula was beautiful, but the M1 (Crab Nebula) felt faint. Also, because seeing was good, I could watched Sirius’s companion star (Sirius well for the first time this season,
but it was a celestial body that was difficult for those who saw it for the first time. Thank you for your hard work! !!
