Tonight I welcomed G. De Cock during the observations, Geert was the founder of Antares amateur astronomy association where I joined in 1999 and where I gained my astronomy knowledge. I was able to observe some comets like: 6P, C/2017 K2, C/2019 T3, C/2019 U5, C/2020 PV6, C/2020 K1. With the C11 and spectroscope I could observe the nova RS Oph, V357 Lac and 28 Cyg.
