    I enjoyed your video on noise reduction. I use Starry Landscape Stacker and generally do 8 back-to-back photos…but next time I’ll try 20+. I also like the tip on the white noise…the penlight method to reduce the white dots.

    I stumbled onto your video by google searching “Corona arch Milky Way.”
