Hi, dont mean to be rude, but there still quite a bit of walking noise on the image

the stars mask it , but in the starless image the walking noise is there

i actually find photoshop colour denoise really good for getting rid of the WN (mostly)

[formal bramble]

I tend to agree with you, but the more sliders we move, more noise we add back, its a fragile balance

Ok when I did a quick edit I didn’t see it but I’ll try to get some more data when I can to get rid of it would u be able to send me ur edits of it too?

Here it is, no changes into colours, only DBE / BXT / SPCC

stars

[lament mica]

bxt before spcc??

[formal bramble]

correct only, then sppc, then regular bxt

Being honest, I usually do both ways, and check what feels better image wise, sometimes it can make a difference, sometimes you cant barely see any. same image bellow, one was done DBE SPCC BXT, the other DBE BXT correct only, SPCC, BXT

[lament mica]

bxt disturbs the colours of stars, causing deviations in the SPCC linear fit samples

if youre looking for accuracy, always spcc before bxt, or any non-pure processes

HI, not accoring to the new documentation of the new BXT preserves flux according to Russell, so all BXT should be done prior to SPCC.
