cmos接收了数个小时的光子
爱因斯坦提出光电效应
让我们可以将光子转化为电信号
经过校准后 呈现在我们的面前
让我们看见宇宙的深邃与神秘

补拍平场之后重新研究了下usm和反卷积
深空摄影就是不断地重复后期同一张图[doge]
随着技术的提升不断地压榨每一张片子的细节
这也是为什么严格要求深空摄影的前期拍摄
亮场要求我们赤道仪和镜子的完美配合 赤道仪提供精度保证 镜子要求星点细腻 完美合焦
bias darks flats的严格准确
引用游戏猫的话就是前期校准的越准确 后期才可以走的越远
因此这是最严肃的摄影题材之一 https://t.cn/RJ2IpDz

Time
Time is aging
Washing away temptations & feelings
Time is a river
Producing deposits &
Clearing wastes
Time is tide
Flatting ups and downs
Time is sunshine
Watching both brights and darks
Time is verdict
Announcing birth and death
Time is law
Regulating rules of the universe
Time is creator
Delivering messages from the GOD heaven https://t.cn/RDUBkfz
