Would anyone like to process some RAW data?
I used 2 x drizzle on Centaurus A in many different modes
for all 12 x 10 minute files & found that median gave the best results.
I processed it & then used it as a luminance layer for my
picture & behold all of this detail popped out!
I have uploaded the RAW stacks for anyone wanting to process
this Southern hemisphere target.
Centaurus A
These first 4 are the LRGB at 600 second frames stacked:

The next 3 are RGB at 120 seconds for purists who want to
get correct star colors on the many bright stars which exceeded the well depth.
Process for the star colors only -
then using this method if you want to in Photoshop:
Select color range, highlights, select modify expand by 4 pixels
& feather by 2, then play with curves & vibrance etc
then copy & paste into the original pic.

Next is a medium stack of 2 x drizzle on all of the 600s frames.
It can be used as a luminance layer to bring out more detail in the galaxy.

Here is a reprocess of the last file placed as luminance on the galaxy.
