Re: [APML] New attempt at processing M16 image



Hi Bert,
  I hope you had a nice Thanksgiving, I'm still trying to recover from over eating. <g>
 I was just on your web page looking at your "excellent" CCD version of M16 and your older film version. I was told that
the yellow star in the upper right corner of my image should not be yellow. Although the star is out of view in your CCD version I see
the same yellow star in your film image. I was going to remove the yellow out of the star in my image but I think I'll keep it.
Real or not I like the looks of it. <g>
 Thanks again for your write-up, on images where the stars are a little out of focus it can save same images from the trash heap.
Joe.

Thanks for the suggestion, Joe --- I'm in process of adding that tip right now.

Thanks Bert,
  If it wasn't for articles like yours to use as a guide I would be lost.............  I can't find my way out of the woods yet but at lest I can navigate from tree to tree. <g>
  I was wondering if its possible to deselect individual stars after using the Color Range tool to create a group of stars to modify? I tried using the Magic Wand and right clicking on the image and selecting the "subtract from selection" option but it removes all the stars. Do you have any suggestions for me to try? 
Thanks, Joe.

Hi Joe:
That's a huge improvement! I think it may be time for *you* to write an article on how to process these things <G>. I know what you mean about the dark circles --- a lot of manipulations tend to do that and the only way I've discovered to avoid it is to apply each manipulation in very small increments and then repeat until the effect you want is achieved or the circles appear. In the latter case, just use the Edit/Undo command to go back to the last iteration.
Keep up the good work...
Bert

Hello,
The only good thing about all this bad weather is that I have time to try to improve on my processing skills.
Not being satisfied with my first attempt at processing my M16 image I gave it another try. With this attempt I was
able to apply same new techniques (new to me) using "Correcting for Vignetting" by Tom Diana and "Reducing Star Bloat" by
Bert Katzung 
 
The one concern I had after using Bert's process is I noticed rings around the stars that were adjusted, but only at high magnification.
 
 
Here is my second attempt: (select image to view previous attempt)
I was happy with the yellow stars that showed up in my new image.
 
Thanks, Joe Schaefer
