Hello to the group,
Here are my visual comet observations from 21 Aug. All of them were made by
my own telescope (355/1650 Dobsonian). Sky was good, naked eye limiting
magnitude was at about 5,5-6,0. Far suburban site, Göd, Hungary.
C/2016 M1 (PanSTARRS)
Aug. 21,83 UT, m1=14,8, d=0,33' (20"), DC=0. 0.35-m L, 351x. Coma is
diffuse but very obvious.
C/2015 O1 (PanSTARRS)
Aug. 21,85 UT, m1=14,3, d=0,4', DC=2-3. 0.35-m L, 351x. Coma is next to a
14.5 mag star, but very obvious. Moving was detected in a half an hour
period.
C/2015 VL62 (Lemmon-Yeung-PanSTARRS)
Aug. 21,92 UT, m1=14,2, d=0,5', DC=1-2. 0.35-m L, 351x. Slightly difficult
to see, but its OK. Moving was detected in a 20-min period.
C/2016 N4 (MASTER)
Aug. 21,94 UT, m1=14,8, d=0,4', DC=0. 0.35-m L, 351x. Bit difficult to see,
but I'm sure its real. Movig was detected in a half an hour period. 15,4
mag stars were visible.
In this night I got a clear view about NGC 7009 (Saturn nebula) with its
lobes, and also about Campbell's Hydrogen Star, which had really, very-very
red colour!
