m63_050306_12i60m_L.FIT (Luminance, 60 min, 5-min subs)
m63_050306_4i20m_R.FIT (Red, 20 min, 5-min subs)
m63_050306_4i20m_G.FIT (Green, 20 min, 5-min subs)
m63_050306_4i20m_B.FIT (Blue, 20 min, 5-min subs)
(Jim's color combine ratio was R : G : B = 1.0 : 1.2 : 1.2)

Use MaxIM DL to do a Non-Linear Stretch (DDP) on the Luminance Frame, with DDP parameters:

• Background = 4200
• Mid-Level = 5400
  
  

• 1.00 - Red
• 1.20 - Green
• 1.20 - Blue
  
  

Note that I have checked the Bgd Auto Equalize button.

Use MaxIM DL to do a Non-Linear Stretch (DDP) on the RGB Frame, with DDP parameters:

• Background = 1000
• Mid-Level = 1300
  
  
  

(magnified to 100% viewing level)

First, create an Inverted Layer Mask for the image.

• Menu selection Image | Adjustments | Levels or keyboard-shortcut Ctrl-L
  
  

Change the Input Levels in the Levels dialog box to 100, 1.0, 235. The 100 darkens the darker areas, while the 235 lightens the lighter areas. These parameters, of course, can be chosen to obtain the desired effect.

• Menu selection Filter | Blur | Gaussian Blur (no keyboard-shortcut)
  
  

Use a blur radius of about 1 or 2 (2 was used here).

• Menu selection Filter | Blur | Gaussian Blur (no keyboard-shortcut)
  
  

Use a blur radius of 3.

请问第一步对L做stretch的Mid-Level=5400在哪里输入？只有min和max啊

这里省略说明了，MaxIm DL先做DDP拉伸，
一般参数Background在auto后，再减200，OK，
然后Ctrl+H ，滑块选0~66133

收藏 ！

果断收藏

看不懂。。。。。。。。。。。。。。。。。。。。。

完全看不懂，目前为止还没成功叠加过一次照片！叠加半天也没什么效果

虽然现在没玩深空，但是这等好资料 一定要收藏了 感谢LZ LZV587!

不错不错 。顶奥

照着做了一次， 学会了 蒙版， 但是随后的处理任然不明白
