如果來了就請大家用力拍吧.. 牛頓雜誌新一期在印 ,有人圖會刊.. 每次看到國外雜誌 APOD 都是外國人拍, 其實很多同好圖都
 拍得很好, 但可能國外雜誌 還是以歐美為主.上次投稿有回信一下, 但後來就沒下文.

剛剛模擬了一下, 2013年4月10號之後 接近天亮有機會拍到, 靠近北方地平線, 亮度5.x

20x10 second exposures. C11 SCT and Starlight Express MX7c CCD imager.
Right - digital development filter to reveal tail curvature in the head of the comet.
C/2011 L4 has the potential to become a very bright southern comet in evening twilight during early March 2013,
later becoming a Northern Hemisphere spectacle by March end.

有人看懂這圖嗎??



UPDATE

有一些新發現的彗星.

[曹大貓咪]

現在經過觀測者的數據收集,在軌道要素中,有兩個肉眼星等指數,-4.0和+1.0.這會決定在最高星等m1(肉眼可見星等預估)曲線的PEAK值.根據曲線,現在觀測者數據m1,這些數據多以-4.0的預估曲線發展.,但最後數據組有慢慢往+1.0曲線修正趨勢...若沒意外,應該會是達0-1等的亮彗星...

這類大彗星,準備135mm鏡頭就粉足夠了....哇,,越來越興奮了...

thank you , 明年主力是看彗星

希望尾巴要長點..

彗星 PanSTARRS 星等預測仍存變數
http://www.hkas.org.hk/news-detail.aspx?id=200

這顆仰角在三月多還是很低阿.日落後沒多久就消失了...
 是否要4~5月台灣比較能看到?

3月底,這顆彗星能有0等左右也粉嚇人了(老貓想或許最亮的時候2等左右就不錯了)....鏡頭以100-300mm為主了...一到黃昏就要搶拍了,所以拍攝的時間粉短(仰角不到20度)...大長鏡頭機動性就差了...取景也不容易.
