Cool Centaurus A 120 hours, Take Two

Hi All,

Having spent much of the past year exploring new image processing tools and refining skills in that area I felt it was time to do a repro of my 120 hour Centaurus A image. I'm still happy with the original version, but... one cannot sit on such a pile of data without making the most of it

Below is a link to the full resolution new version of the image. I think it's a big improvement over the original - it's even hard to see it is the same data!
This time I was able to bring out the concentric shells much more and at the same time give the image a more subtle natural look. One might even say this version respects the light

I started from scratch and did a complete re-registration and combine of the data again, followed by about two weeks of nightly tinkering in PixInsight. The new version also has slightly higher resolution than the old one, despite it looking more relaxed and less 'processed'.

Link to full resolution image (3.5MB)

All details about the image acquisition and what is visible are still the same as in the original thread.

Hope you enjoy this new take on the extreme deep field. All comments and critique welcome as always.

Regards,
Rolf
