First time using CLS filter, they cut the glare from air glow but also cut the detail and definition and leave the image with a blue tinge ( Yes I know , you can massage the image through stacking and processing and get a near perfect outcome but I'm trying all different things to get the raw image the best I can without the help of the silicon chip )
Also doesn't help if your not polar aligned close enough as well
