Thanks Alex, yep they are pretty dim.
I redid NGC1672 and 1596 today and tried a 2x Bspline resize-process-resize back
routine.
I keep making the same mistake and doing the processing in the dark
loungeroom, 2am-ish , while very tired.
Not a great LCD screen environment to judge near black levels etc.
I wrote this routine down because it seemed to work a lot better than
last night's routine.
Subtracted darks.
Made Bad Pixel Map.
Subtracted BPM from lights.
Resized lights 2x Bspline.
Stacked lights.
Applied curves
Applied sharpening.
Noise reduction in Neatimage (freeware) on auto.
Resized back to 1x
Edit: btw it just occurred to me that this was about 45 deg up
and the DSI sensor was sitting on no lower than 22 deg C
