好像說 10~12 等間 還不夠亮..
有上山或許 可以連加洲星雲一起拍看看

請問一般我們使用 stellarium 軟體用哪一個座標會比較好?
赤經/赤緯(J2000): 
與
赤經/赤緯(J2000):

有何不同?

J2000的意思是2000年 春分點的天球座標系統
有(日期)的那一項是指以現在的天球座標系來看的值

其實差異是有, 但是 比較小  .

[ Altitude: 4 deg. Astronomical twilight. Zodiacal light.].
2015 Nov. 23.25 UT: m1=5.7, Dia.=4', DC=5, Tail: 0.2 deg.
in PA 280 deg.; 25x100B.
[ Altitude: 5 deg. Comparison stars at the same low altitude
as the comet. Astronomical twilight. Zodiacal light. Observation
made under better conditions, from a higher and darker mountain
location, providing a wider coma diameter and brighter m1
estimate in comparison with my previous Nov. 22.25 observation.].

C/2014 S2 (PANSTARRS):
2015 Nov. 23.21 UT: m1=8.5, Dia.=6', DC=4, 10x50B.
[ In 20 cm SCT (77x): m1=9.4, Dia.=4', DC=5, Tail: 0.15 deg. in
PA 30 deg.; near-stellar central condensation, m2=11.5: (Tycho-2).].

C/2014 W2 (PANSTARRS):
