In our region, NLC's are seen around midsummer night and mostly photographed an hour and a half after sunset or before sunrise when the higher parts are light up. But at these moments the sky isn't dark enough to see them together with the starry sky. In previous years I did a lot of observation during the darkest hours of our short mid summer nights. In fact it never gets completely dark. Here, I present a view of the NLC's on June 22, 2018 at 00:57 UTC. So just before the
first morning light (beginning of dawn) and with the starry sky still clearly visible.

Constellations on this pano are: part of Ursa Major and Lynx at left, part of Auriga in the middle above the horizon, part of Perseus right of the middle and higher in the sky, part of Andromeda at right, high in the sky and with Triangulum below (please check pano 27882 and 25800 with constellations drawn).

The orange glow in the middle is reflection from the Port of Rotterdam at 67-75 km. It is even possible to distinguish the lights from the big plants of Exxon and Shell.

"So just before the first morning lights" 
What do you mean exactly? At what time do the first sunrays appear, at your latitude in that period of the year?
Amazing photo, both for aesthetical and technical facts.
Ciao, Alvise

"Dialog" von natürlichem Nachtlicht und Lichtverschmutzung. Beachtenswerte Präsentation.

Kleine Anmerkung: schwarze Schrift auf nachtschwarzem Himmel ist nicht gut lesbar.

Schöne Grüße,

Hi Dieter, when I click on a star I annotated, it appears as a black text in a white box. Do you see this differently?

Hi Alvise, I mean when the first morning light becomes visible to the naked eye without the NLC's. Of course this is not an exact moment and around mid summer night it never gets completely dark above the northern horizon. But lets say around 1 am UTC (3 am CEST) one begins to notice the upcoming dawn. But with the white-blue NLC's present, it gives the impression dawn starts earlier than normal. Compare with my comet pano 27882 at 3.23 CEST and you see the increase of light.
Sunrise on this day was at 5:29 CEST so two and a half hours later than this pano.

@Mentor, click at "Overview on", and see your black letters on dark background ...

Ha ha ha ... =:-O 
... first I was also searching for NEOWISE on the photo, but then I saw it was taken in 2018

Hi Oliver, Neowise you can see on my previous panos 27882 and 27788 if you like, thx.

Mentor, sorry wegen der späten Antwort.
Wenn du den "Overview" anschaltest, dann wird die Schrift in der Farbe eingeblendet, die du beim Labeln verwendet hast. Und da die Voreinstellung "schwarz" ist, sieht man halt bei nachtdunklem Himmel nichts. Du kannst aber im Nachhinein die Farbe noch ändern.

hi Dieter, I changed the setting to a red, then white color but it seems this doesn't work afterwards. And if you cycle though labels, do you get the white boxes with black text one after the other? Anyway that is what I get. But indeed the overview is in black. Personally I don't use this because it obscures too much of the scene.
