Description

This image was taken under a very polluted sky ( yellow-red zone ) and with high humidity. I am very impressed about how much signal I acquired and I have to say that the L-Pro filter worked very well against the light pollution! I had to integrate a lot because of the sky which was not so good.
Very satisfied of this result!
