a better version
Stacked 71 photos using DeepSky Stacker.
All photos were taken using 50mm, f/2.8, ISO800, 6s.
Defraction spikes were added in photoshop.
(more...)
71张照片叠加曝光
signal equivalent to 6s*71=426s = 7min6s exposure.
noise level equivalent to (71)^(1/2)*6s = 50.5s normal single exposure.
btw, 还是觉得曝光不够。看到人家杂志上拍的比这个亮得多。
