At the age of 17, I took my first successful astrophoto. Sejak menyaksikan misi NASA Apollo 11 ke bulan semasa kanak-kanak, saya selalu terkesima dengan keindahan dan misteri jagat raya. Pada usia 17 tahun, saya pun berhasil membuat karya astrofoto. Living in a light-polluted area, I must travel for every imaging session to get the dark sky that is required. As a lighting engineer, I know very well the issue of light pollution. My astrophotos show not only the beauty of the starry night, but what we are losing with an indiscriminate and inefficient use of artificial light which dramatically reduces the visibility of stars and, like any other form of pollution, disrupts ecosystems and has adverse health effects. Tinggal di area berpolusi cahaya mengharuskan saya melakukan perjalanan dalam setiap sesi pemotretan guna mendapatkan langit yang gelap. Sebagai insinyur bidang pencahayaan, saya mengerti betul masalah polusi cahaya. Astrofoto yang saya buat tidak hanya menampilkan keindahan malam berbintang tetapi juga menunjukkan apa yang hilang akibat pemakaian lampu-lampu yang tidak efisien, mengakibatkan bintang-bintang tak lagi dapat terlihat dan seperti halnya polusi lain, polusi cahaya mengganggu ekosistem serta berdampak buruk bagi kesehatan. Helix Nebula (NGC7293) Located in the constellation of Aquarius, this nebula has been nicknamed the ‘Eye of God’ and is a typical example of a class of objects called planetary nebulae. The central star of the Helix Nebula was once a star very similar to our own Sun. The remnant central core, known as a planetary nebula nucleus, is destined to become a white dwarf star. Our Sun will blossom into a planetary nebula when it dies in about five billion years. Berada di rasi bintang Akuarius, nebula ini dinamakan “Eye of God” (Mata Tuhan) dan merupakan contoh objek yang disebut nebula planeter. Bintang inti dari Nebula Heliks awalnya adalah bintang serupa matahari. Sisa dari bintang inti, yang dikenal dengan nukleus nebula planeter, menjadi bintang katai putih. Matahari diperkirakan akan menjadi nebula planeter ketika mengakhiri hidupnya dalam kurun sekitar waktu lima miliar tahun. 23
