Below is my workflow for this image for those who are interested
Just remembering that workflows vary from image to image so just using this workflow with its parameters may not produce a satisfactory result on your specific data set
It’s only used as a general guide

Nice, Martin. I like those grayscales too.

DEC -61. Sigh. You've done it again.

Oh well, I suppose we do the same with M81/82 and all else. There's great stuff everywhere, but south celestial does seem awfully nifty.

Is that the same data on a-bin but as different uploads rather than revisions?

Thanks Mike,
All images same data and obviously different Color

I added my workflow as I’ve seen folk ask for help on a few occasions processing with OSC and Dualband filter datasets

Looking forward to our Galaxy season ( March to June ) in the Southern Hemisphere

Cheers
Martin
