RE: [APML] Redo- Sagittarius - M8 to M17
Hi:
You can see another version or representation of the same field of view forward the Redo- Sagitarius - M8 to M17 topic. The process has been made exclusively with PixInsight. I think there haven't a soft look.
Cheers,

Gary,
I am just now seeing the results. It looks very good. For a comparison,
check mine out, it’s also E200 but with a 135mm lens. I'm sure that
Wei-Hao's would be a better representation, but ... here it is anyway.

Hi Alan,
Thanks! As for processing steps, after my initial Histogram balance, I
did a Curves, Wavelets, SCNR, and SGBNR. After each step I check the image
in Histograms to make sure I'm not clipping anything. After I'm finished in
PI
LE I put
the image in PS for a Auto Levels with a Fade adjustment, an
Unsharp Mask with Fade adjustment, and a Minimum filter with Fade
adjustment. I think the "softness" comes mainly from SGBNR. I do not
possess a great knowledge of the Wavelets or SGBNR, I just use the tutorials
as a guide and really don't deviate too much from the values used in them.
When I get time I'll try a version in PS alone to see what the difference
is.
Gary

Hey Gary,
This is an improvement. I'd like to ask what processing steps you did
in Pixinsight. Did you do more than a DBE? I have to ask because this
shot has taken on the 'softness' that I always see with images that are
extensively processed in Pixinsight. To this point I have not
heard
a
reasonable explanation of why this is, but it is.
I can now tell as soon as an image pops up where it was processed. I
wonder if you'd be willing to do a version in PS only as a comparison.
Thanks,
Alan
