Am I right in assuming that you would still need to deal with light pollution the same as any other focal length scopes?
I'm just thinking about what scope I might like to move to next.

I do deep sky imaging at 3m FL occasionally and you really need to pick your night. No or very little jetstream is a must and no surface wind also goes a long way with tracking/guiding. That said at that FL light pollution and gradients are much less of an issue. My C11 has a very long dew shield and flocked all the way so I have very little stray light and good contrast both visually and imaging.
