What I was wondering is whether each color exposure was equal, but I didn't express that well.
I may have finally come across what you were looking for (I'll learn this stuff yet). The way CCDSoft works is you first open the four (luminance, red, green and blue) filtered images and then click on an icon labeled "Color Combine". That opens another window where you tell the software where each of the 4 images are and then click on "Combine". Then some magic happens and the color image appears. However, after reading your message from this evening I went back and looked at the Color Combine window and saw that while the software makes the ratio choices automatically it will also allow the operator to change those settings. The automatic settings for the M-51 shot were Red ratio 1.0, Green ratio 1.0, Blue ratio 1.0, Luminance transparency 1.0. Is that what you were looking for? BTW, I spoke with Jerry Foote a few hours ago. He's my mentor in this stuff. Up to now all of my pictures have been binned 3x3. He's suggesting I try shooting the luminance frames at 1x1 and the colors at 2x2. 1x1s will take 9 times the exposure length of 3x3 but I'm interested to see how thy look (I tried to find out tonight but it clouded over). Next I'll need to figure out how to use CCDSoft to merge 1x1 and 2x2 images.
I have a few bad pixels as well. When you got rid of yours, was that programmed in before you took the views, or processed afterward?
Afterward. In a three step process using two softwares. Something called PicFix works with CCDSoft to remove the bad columns and another software called Scrubber works with CCDSoft to remove first the cold pixels and then the hot pixels.
PS: Gotta brag. Our son, Sky, successfully defended his Ph.D. thesis yesterday at the University of Arizona.
Kudos to The Doctor! (Not to be confused with the Time Lord of the same name. <g>)
Also, just FYI and way OT, I should be on Ch. 7's Utah NOW, Friday evening at 8:30 p.m., discussing why the supposed daguerreotype of Joseph Smith isn't him.
Excellent. I just set my DVR. Cheers, patrick
