上週天氣預報完美,實在太耐沒有觀星了!每天繁忙的工作,星期六晚是唯一的機會作天文拍攝。時間有限在趕急的情況下把TMB 105/650,兩支相機鏡頭和D810A等儀器收拾好,然後更出發。在搭車途中突然一沉,發現自己忘記帶望遠鏡的鏡箍!結果是不能用望遠鏡,幸好今次除望遠鏡頭外也帶了兩支相機鏡頭,當中Sigma 50mm f1.4的表現非常之出色,在平日拍攝而知她比原廠的50mm f1.4 G鏡頭好!幸運之神在我身邊,星期六晚的天空清晰,Sigma 50mm f1.4Art 也助我完成這張美妙的天鵝!
The weather forecast last week was promising. However, I would do imaging only on Saturday due to works and family man duties. With limited time, I packed all my equipment all in a rush and went to my Astrobase. I brought my TMB 105/650 and two camera lenses and D810A etc. In the middle of the trip, I suddenly notice that I forgot to bring the telescope tube rings! It ended up that I could only use my camera lenses to do imaging. I seldom do wide field imaging. This was a chance for me. God of lucky was inside me, the sky was clear on Saturday night and the extraordinary performance of Sigma 50mm F1.4 Art made this image of Cygnus spectacular!
