Landscape

夜幕降臨，閃爍的霓虹蓋過星空。匆忙的我們，曾幾何時也是仰望星月交輝的少年。

若許久沒有駐足於繁星之下，不妨在城市的一角，靜靜欣賞月光吧。

C/2023 A3 Tsuchinshan–ATLAS 紫金山-阿特拉斯彗星

【拍攝時間】2024/10/12

【C/2023 A3 紫金山-阿特拉斯彗星】人生第一次拍彗星，成就達成！！去年 2023 年 2 月這顆彗星被命名後，就開始期待這顆彗星的到來。九月底時，彗星上半場剛好颱風經過，只好等下半場的機會，剛好下半場頭幾天天氣都不錯，於是著手進行拍攝計劃。

10/11 先勘查場地，順便模擬角度和取景。彗星西沉的角度，剛好和附近斜屋頂成對角線，構圖上不會有太大問題。今天 16:45 就到拍攝現場準備器材，順便拍日落 XD

只不過第一次拍彗星沒有經驗，從 17:00 開始拍，看著夕陽西沉，然後開始嘗試各種拍攝參數，低仰角真的是一大挑戰啊！不過在 18:00 左右，終於拍到彗核的小亮點，開始手動 GOTO 追蹤，終於拍到一張自己滿意的照片。

介紹一下這顆彗星吧！C/2023 A3 首次在 2023/02 被中國紫金山天文台發現，並以此天文台命名，是顆長週期性彗星，因為未來軌道還不是很確定，因此它很有可能一去不復返 XD

在 10/20 以前，亮度還是維持可以用雙筒望遠鏡觀察的程度。如果有雙筒或單眼的朋友，不妨在 10/20 以前拍攝看看吧！！

[C/2023 A3 Tsuchinshan-ATLAS] Successfully photographed a comet for the first time in my life! ! Anticipation for the comet‘s arrival began after it was named last February 2023. At the end of September, a typhoon happened to pass by, so I had to wait for the opportunity to get closer to the earth. The weather happened to be good these days, so I started to plan the shooting.

10/11 First survey the site and simulate the angles and framing. The angle at which the comet sets in the west is just diagonal to the nearby sloping roof, so there won’t be much problem with the composition. I went to the shooting site at 16:45 today to prepare equipment and take photos of the sunset XD

But it was my first time to shoot comets and I had no experience. I started shooting at 17:00, watching the sunset, and then started trying various shooting parameters. The low elevation angle was really a big challenge! However, around 18:00, I finally photographed the small bright spot of the comet nucleus, started manual GOTO tracking, and finally took a photo I was satisfied with.

Let’s introduce this comet! C/2023 A3 was first discovered by the Purple Mountain Observatory in China in 2023/02 and was named after the observatory. It is a long-periodic comet. Because the future orbit is not yet certain, it is very likely that it will never return XD

Before 10/20, the brightness was still enough to be observed with binoculars. If you have binoculars or a camera, you might as well take a photo before 10/20!!
