Subject: Re: [APML] M51 RGB (only)
John and all,
Thanks for the kudos... the
"saturation" of the colors is the natural result of all-RGB information... I
noticed the same thing... so now the challenge is to somehow combine this with
a sharper "L" and not loose any of that.
The reason that an "L" is still a good thing is
because the filters along with the IR blocking filters cut back on the light
immensely that the CCD is sensitive to, so the amazing depth that one can get
through the "clear" mode is nowhere to be seen... as Rob put it, a CCD in
color mode isn't much more sensitive than film!
The slight lack of alignment
is puzzling to me, too, but I would be willing to bet it is from all the noise
that is in the file. I had huge amounts of cosmic ray hits over the last few
days, perhaps from the solar activity adding to the random hits. Registar has
no way of knowing if some of these are stars or not... the new version has
noise suppression filters which do help. The problem is that I can't
see the noise to retouch it out before Registar without
corrupting the data. If anyone has any ideas, I'm all ears...
