Hello. I was making an image of the Mimosa and the jewel box and I noticed vertical gradients (evidently green).

Investigating (greatly increasing the saturation of the previous images) I noticed this effect in other images (using other optical sets). But more pronounced in this one. Does anyone have a solution?
Thanks!

Samyang 135 @ F3.2, 60 x 60s
gain: 102
UV-IR cut (tested without and bands remain)
Bordle 7-8
single frame:

Only a ligth ABE, stretch and saturation boost were applied (to highlight the bands)
I will try to increase the gain next time, since i read that low gain can couse that effect...
