C/2020 M3 (ATLAS) is moving farther away from earth but is still relatively near at distance 0,45AU. I tried to observe comets rotating CN gas jet which was visible earlier 20.11.2020. Seems that the CN jet is still visible but clear rotation is no more observable.
Figure 1) CN 387nm filter 18*5min exposure starting at 2020-12-09 22:47UT, showing large 15' (equivalent to 300 000 km) cyanogen coma around oval shaped optocenter. FoV 36' x 29'.
Figure 2) G filter 20x20s image at 2020-12-09 19:56UT showing tail 4'. FoV 36' x 29'.
Figure 3) R filter 20x20s image at 2020-12-09 19:44UT showing dust tail 3'.
