Hello,
Been doing some studying the
last few days... trying to learn more about post processing techniques with the
raw CCD data... here's something you will probably want to see.
Instead of averaging the
six M51 shots, I co-added them together... this is closer to "stacking" the
images in the old days with film... more detail shows up, but also more noise.
After this, I used CCDsharp to add some mild deconvolution, then I added a mild
unsharp mask to make the stars hard edged. My goal... to bring out as many of
the anonymous galaxies behind M-51 as possible.
I kept a portion of the galaxy
in each shot for scale... to me it is mind boggling that I am using M-51 as a
reference object... the real picture in each of these shots are the many
galaxies (and perhaps very faint stars) that populate the field. I tried to make
the stars hard edged so we might hazard a guess between faint star and
galaxy...
Here's the
results:
Have a good
one,
Tony
