Sketch video of M17 the Omega Nebula video is now posted to youtube here: https://youtu.be/ifcZjVYOPQU This was done in early hours of June 16, 2020. I had to use an Orion Ultrablock filter to cut through the light pollution in my southern skies. I also used black canson paper, white soft charcoal pencil, white pastel pencils, blending stump, and a kneaded eraser for drawing this object.
My skies to the south are severely light polluted and I usually try to not do much in that direction, but I wanted to give some of these summer objects a shot while I had unbelievably clear skies (for summer). While I wouldn't say the ultrablock filter is a tool that removes light pollution and brings out more nebulosity, but I can say it did help with the contrast and helped me tell the difference between light pollution and nebula. I can't wait to get to dark skies and also try this filter out I think it would be a lot better if you don't have light pollution to combat.
