Hi Chris,
That’s really great stuff and really important too.
I think it is really important not to conflate conventional light pollution from badly designed lighting and the effect of satellite mega-constellations. The two impacts are very different. For most people living in towns and cities the former has a much greater impact than the latter. The satellite constellations really only impact imagers and there are (usually) ways to mitigate the trails on images. I have been to really dark sites recently where the Milky Way looks like an illuminated cloud and visually the satellites don’t have any impact on the view event during late astro twilight. They are all over my images but there are ways of handling that.
We should be concerned about both of course but the former has a much greater impact on the vast majority of people (including most amateur astronomers) and we need to be careful not to equate the two from an amateur astronomy perspective since I think that weakens our argument when it comes to bad lighting. Bad lighting has no positive benefit to anyone but satellites certainly do. The impact on pros is much worse of course and so our advocacy is certainly very important in terms of getting operators to mitigate the effect of their spacecraft.
Nick.
