拍獵戶座大星雲 M42作熱身
冬夜的北風會吹走城市煙霾, 天會清一些, 適合深空天體的拍攝. 昨晚先拍獵戶座大星雲 M42作熱身運動, 一切順利. Orion M42 Nebula, HKT 2021/11/07, 00h43m to 01h02m, Canon700D Camera, IR filter removed. Soligor 450mm lens f/8, Astronomik lightpollution filter is used. ISO 1600, Exposure 40 sec each, RAW format. Use DeepSky Stacker software to stack 16 light frames, 10 dark frames, 10 Bias frames,and 10 flat frames. Final touch by Microsoft Photo. The place where the photoswere taken in Kennedy Town, Hong Kong.
