What might possibly also work is to perform sensible noise reduction on O3 and S2 masters before integration

You'd need to watch the weighting carefully to check that the noise estimation didn't go too crazy but it would be worth a try.

That's a really good Keyhole region shot Lee. I don't mind the palette and although the decon police can recognise the decon in places , it is not obvious and most of the detail looks very normal Good that you can also make out Eta's Homunculus too, nice work

This area doesn't really need heaps of data, as this result clearly demonstrates

As for the workflow thing, I guess I've never considered STF as a serious option for stretching. It's meant for previewing, right? Why not call it auto-stretch if it's meant for one-click stretching?

I actually did use STF for the sii / oiii / ha shots attached, but I'm not sure I could give up control and leave it all to STF for my "real image".

Hi Lee, you can tweak the STF if you don't like it, then apply your preferred stretch to the histogram, or you can just use the histogram to stretch without relying on the STF. The point is that it is not necessary to use Curves at any stage of the stretch. Histogram is all you need.

This is all explained here http://harrysastroshed.com/pixinsigh.../histogram.mp4 in much greater detail.

Thanks Mike! lol. I'm not surprised the decon police caught me red-handed with this one. I did overbake it for sure.

Thanks Geoff! I don't see myself doing away with curves or doing little tweaks, but I may now use STF as a starting point. I got some HA data on Gabriela last night and did so with that, and was reasonably happy with the results after comparing to what I got when doing a manual initial stretch.
