Stitching a mosaic created in ASIAir

Software Siril
1

Hi all, apologies if this has been covered already.

I’ve created my first mosaic using an ASIAir Mini. Erring on the cautious side, I created a 25% panel overlap. After following the Deep Space Astro mosaic video and the Siril book, I have 2 stacked panels, both 3004x3004 px, ready to be joined.

My newbie question is: in Stack Stitching, do i make the Border Feathering 25% of 3004px, or 750px, or is this a value to be played with?

Thanks in advance for any help/advice.

I went with the full 25% overlap to feather, and I think it came out well. More experienced eyes may notice something?
