Can you process out 'walking noise'?

[Synchronicity]

I'm guessing that's what I have here.  This is 3 hours with my ASI 183MC pro cooled to -15C.

Stacked with PIs WBPP using mostly default settings though on this run I had Linear Defects Correction enabled.  I haven't dithered so far and I've not had this with the other 3 nights of data collected as I 'tune in' my setup.

So, can anything be saved from this data?

Attached are a screenshot of WBPP output with STF applied, the Blink video and a random raw image.

Thanks

You can in startools to a degree @jager945

Yes, to a certain degree

Photoshops dust and scratches filter can tame it a little bit but won't get rid. You could also Gaussian blur it a 1 or 2 pixels with the stars deselected.

Did you try NoiseXTerminator? (on PI)

Just did a quick test with your colour image as I didn't notice anything obvious on the Fits file after running de-noise - I did a DBE as well

Sorry I am a bit new but what object is this? Looks very cool!

It is SH2-101, the Tulip Nebula.

I was going to link to Astrobin images of it but the site seems to be down just now.

I haven't had the chance to try the suggestions here yet.
