Stacked 71 photos using DeepSky Stacker.
All photos were taken using 50mm, f/2.8, ISO800, 6s.
Defraction spikes were added in photoshop. [吴永铮 (1-27 15:16, Long long ago)] [ 传统版 | sForum ][登录后回复]21楼

(引用 吴永铮:a better version Stacked 71 photos using DeepSky Stacker. All photos were taken using 50mm, f/2.8, ISO800, 6s. Defraction spikes ...)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。[毒鼠强 (1-29 20:02, Long long ago)] [ 传统版 | sForum ][登录后回复]25楼
