Hi,
I am looking for a bit of help. I believe I am having a walking noise issue due to not being able to dither my Star Adventurer. Now that I am guiding it seems to have gotten worse. Is there any combination of settings in APP that can help with this? I didn't get this with shorter exposures in the past. Also Deep Sky Stacker seems to deal with it a lot better, so I know there is room for improvement in APP.
I shot about 25 frames at 5 minutes each and I have added darks, bias and flats which I shot to match the same night. I am using a full spectrum Panasonic Lumix GH4 mirrorless camera with an STC Duo Narrowband filter. The attached images are from APP with Ha OIII --> Extract Ha, and from DSS with the blacks brought down to make them more similar. You can see that the DSS images is a lot better. I have tried several settings combos in APP and keep getting this, any help would be greatly appreciated!
I have similar problems. This is my latest stack. APP vs DSS. Same subs 🙁

This is all likely because APP gives a different stretch, so the background comes out more in which you see, indeed, walking noise. Try to dither when collecting data, that will immediately solve that and improve overall results.
