Took 20 180sec exposures with my QHY8L and guider but when I tried to stretch it after DSS I lander up with these vertical lines!! any ideas what I am doing wrong or could do with my original image to get that special one.  Jay

not the best as i only had your JPEG to work with, but its a lot better, are you capturing this data with a DSLR as they are known for vertical banding

i used these actions for PS to get this within 30 seconds, they are some great actions and worth every penny
