借日前海洋公園合作中秋天文嘉年華的照片分享一點感想。8月初時我到華東走了一圈，拜訪紫金山天文台科學家團隊，也跟幾個厰家老朋友聚聚舊 https://www.facebook.com/groups/1836992643243753/permalink/3631382800471386/ 席間大家都談到Seestar這類智能望遠鏡對天文愛好者器材產業的可能衝擊。大家都相信EAA即Electronically-Assisted Astronomy大浪潮已經真正到來，就像進入數碼攝影年代，現在用望遠鏡目視觀星的愛好者比例已較過往少，當Seestar這類智能望遠鏡大規模進入市場後，會像智能電話對數碼相機的衝擊一樣，它會蠶食低端望遠鏡及入門級的攝影裝備市場，但因為接解天文的市民基數大大增加，也可能產生更多高端器材的用戶數目。有些天文發燒友對Seestar抱負面看法，認為這是快餐式的器材，我個人則抱正面態度，正如過往我們當年初中生也熟練的觀星基本功人手Star Hopping、對極軸、手動導星等，現在很多愛好者已無能為力，但今天天文照片拍得遠比當年好。而作為資深的天文發燒友，在某些爭分套秒的天象，例如彗星或日全食，我十分需要有一套Seestar從旁協助觀測，
到底我仍相信，暗黑夜空及目視星空是沒有替代品的，自己動手也是一種樂趣。海洋公園當晚我們裝起Sky-Watcher Dob 16 GOTO 40公分反射鏡，也有Celestron Nexstar 8SE及其他小鏡，再加上Seestar作展示用途，但就像這個小女孩，仍然不忘拿出自己剛親手組裝的紙筒望遠鏡再親眼看看月亮。我在自己的西藏天文台也置了一台Dob 16 GOTO，之前的星空派對我們曾用這鏡目視馬頭星雲、細數M31仙女座大星系漩臂上的雲團、檢視玫瑰星雲上裂紋，明年春帶一團中學生去西藏觀星考察時，我會放一台Seestar在旁拍攝，然後通過實時影像，讓他們用肉眼去對照大望遠鏡中看到從千萬光年外來的光子。智能望遠鏡的到來，是對抗日益嚴重的光害的利器，大大豐富我們的觀星方式及提升觀測效益，它絶對不是洪水猛獸。 

I would like to share some thoughts through the photos taken during the Mid-Autumn Astronomy Carnival in Ocean Park recently. In early August, I traveled around East China, visiting the scientific team at Purple Mountain Observatory and catching up with some old friends in the industry https://www.facebook.com/groups/1836992643243753/permalink/3631382800471386/ During our gathering, we discussed the potential impact of Smart Telescope like Seestar on the astronomy enthusiast market. Everyone believes that the wave of Electronically-Assisted Astronomy (EAA) has truly arrived. Just like the digital photography era, the proportion of visual observers among enthusiasts has decreased. When intelligent telescopes like Seestar enter the market on a large scale, they will have a similar impact as smartphones did on digital cameras. They will gradually replace low-end telescopes and entry-level photography equipment. However, as the number of people interested in astronomy increases, it may also lead to more users of high-end equipment.
Some astronomy enthusiasts have a negative view of Seestar, considering it to be a fast-food-style equipment. Personally, I hold a positive attitude. Just like in the past when we, as junior high school students, were skilled in star hopping, polar alignment, and manual guiding, many enthusiasts today are unable to perform these techniques. However, the astronomical photos taken today are far superior to those taken in the past. As an experienced astronomy enthusiast, I am glad to have a set of Seestar to assist in observing time-sensitive celestial events such as comets or total solar eclipses.
Ultimately, I still believe that the dark night sky and visual observation of the stars have no substitutes, and there is joy in doing things by ourselves. On the night of the Ocean Park event, we set up a Sky-Watcher Dob 16 GOTO 40cm reflector, as well as a Celestron Nexstar 8SE and other smaller telescopes, along with Seestar for demonstration purposes. However, even with all this equipment, like this little girl, still took out her newly assembled cardboard telescope to observe the moon with her own eyes. In my own Tibetan observatory, I also have a Dob 16 GOTO. In previous stargazing parties, we used this telescope to visually observe the Horsehead Nebula, count the clouds on the arms of the Andromeda Galaxy (M31), and inspect the cracks on the Rosette Nebula. Next spring, when I take a group of high school students for stargazing observation in Tibet, I will have a Seestar set up for capturing images alongside. Through real-time footage, I will let them compare what they can see with their naked eyes to the photons coming from thousands and millions of light-years away seen through the big telescope. The arrival of intelligent telescopes is a powerful tool to combat the increasingly severe light pollution. It greatly enriches our ways of stargazing and improves the efficiency of observations. It is by no means a destructive force.
