Starting this season with an image shot in spring. Gathered a lot of exposure time but was pretty sure it wasn't going to amount to anything as the objects were pretty low in the sky glow from Oslo at the time. Had issues with moon gradients as well an haze, but after reading up on LocalNormalization in pixinsight and going over the material again I finally found a couple of exposures in each filter-stack that didn't have any problems, and used these as reference. And what LocalNorm didn't get I was able to diminish pretty well with just a handfull meticulously positioned background samples. You'd expect deeper from 26,3hrs integration time, but all in all I'm just glad all those hours weren't completely in vain.
