Hello,
I made this sketch near the center of a city, where the light pollution is medium. The sky had a little high fog, but I can see the stars very well. But my principal enemy was the small aperture of my refractor . I don’t use any light pollution filter.
My sketch was done with a pencil, on white paper and then reversed the color in GIMP software.
Hope you enjoy!
Best regards
Waldju
