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
