Did anyone of you use an light pollution filter for your night lapses?
Iam usually working with the NiSi system because the 150mm filters work with my Nikon 14 - 24 mm.
They also have a light pollution filter in their portfolio.
I couldn't find much online about it. Only the NiSi marketing stuff.

Any advices or help would be highly appreciated.

Short and sweet: forget those filters. Save the money, buy something useful.

I've tested them, and compared the results with unfiltered images that I've took right after. The filter has two effects:
1.) Color shift
2.) 2/3 Stops light loss.
The Whitebalance of the filtered and unfiltered images are qickly matched in Lightroom, which also makes the "Anti-light-pollution-effekt" disappear.
The 2/3 stops loss of course increases the noise in the image.
So after all, with the filter you will get noisier images than without. The "filter" effect is just a color shift which you can easily achieve in a better way with the WB tool in Lightroom, because you can use that locally also.
Thank you very much for that answer.
I was just about to order one.
So that answer just saved me some money Smile
