（ESCO │ written by TSOI Nga Ching, SSY Ho Lap College│7 May 2021） On April 24, I attended a talk by Schindler Leung, a senior astrophotographer. The talk focused on the skills of shooting photos of the starry sky, different types of astronomical phenomena and the fundamental equipment required. I was impressed, especially by the delightful photos taken by Mr Leung in different places, such as High Island Reservoir (East Dam), Lung Ha Wan and Lion Rock.

Among all the wonderful pictures, the photo taken on Lion Rock caught my eyes the most. In the photo, there is a semicircular star trail, with the hustle and bustle city right below it. It was a combination of peace and flourishment, having an extraordinary chemical reaction. In addition, Mr Leung also shared his advice on choices of cameras with us and I was shocked but excited to find out that we could also take appealing photos simply by using our phones if we adjust the angle and light carefully.

Through this talk, I understand that taking good photos is never an easy task. Taking the star trail, for example, the astrophotographers have to spend at least half an hour to take countless photos and then overlap these photos using specific apps. Even for a simple starry sky photo, photographers have to spend several hours to catch the most attractive moment of the stars, not to mention the shooting of other captivated astronomical phenomena. But of course, for most of the starry sky lovers, taking photos of it is a romantic process of appreciating and enjoying its beauty, more than a task or mission. I feel the same now. This talk also raises my awareness of the serious pollution problem in Hong Kong because we could barely see the shiny stars in the future if we do not devote efforts to lessen pollution right now.

All in all, the talk is very detailed and the speaker is knowledgeable. I can't wait to join this kind of talk again!
