It very rarely happens that we ‘ve got 9 nights in a row (around new Moon!) here in Belgium. Next to the main setup I have put the little SharpStar to use to capture- every night 10-minute frames of this area. Even with the Optolong LPS the large field gave a clear gradiënt of light pollution.
Seeing the tail appear after 145 frames made me smile 🙂
So yes it’s possible to capture this feature in SQM 20 type skies, you only need a lot of patience I guess (or a faster scope).
