APOD: Milky Way over Troll's Tongue (2018 Sep 11)

Milky Way over Troll's Tongue
Explanation: You have to take a
long hike to see the Troll's Tongue -- ten hours over rocky terrain. And in this case, it took three trips to capture the
landform below a clear night sky.
Trolltunga itself is a
picturesque rock protrusion extending about 700 meters over mountainous cliffs near
Lake Ringedalsvatnet in
Norway. The
overhang is made of billion-year-old
Precambrian bedrock that was carved out by glaciers during an ice-age about 10,000 years ago. The
featured picture is a composite of two exposures, a 15-second image of the
foreground Earth followed 40 minutes later by an 87-second exposure of the
background sky. Thousands of discernable stars dot the backdrop
starscape in addition to billions of unresolved stars in the nearly vertical
band of our Milky Way Galaxy.

So whose backside is the troll tasting?

Nice shot imo. Is that Jeb Corliss or Jokke Sommer laying on the Tongue?

Why a 40 minute delay in images? Weather???
Really nice pic...

I should be very wrong but there is no bridge to be seen at Trolltunga. What else is assembled in this "photo"?

Ummm... I'm pretty sure you can't get a near-vertical image of the Milky Way from Norway! I suspect the background was shot somewhere around the equator?!?!?!?

There is no bridge in this picture. Just a distant shore with a couple of lights along it.

Why do you think you can't see the Milky Way at this angle from Norway? You certainly can. I'd be interested to know the date and time the image was made. A bit difficult to get a truly dark sky from that latitude during mid-summer. Unfortunately, the imager doesn't seem to have a webpage, just some fairly useless social media links. So not much additional info. (I do wish that APOD wouldn't accept images without technical information.)

Sorry sorry, I was wrong. By magnifying I am see it myself. I am so sorry!

Sorry, I was wrong! It's not a bridge but there are lights at the the end of the lake ... no fake, as far as I can tell ... sorry

Wow. There is such cloud cover in the foreground picture, It seems incredible that they got a clear Milky Way shot 40 minutes later.

Hi,
this scenery was used also for a musicvideo by the norwegian band "Shining"...

The music is special ^^

700 meters?? It looks more like 70 meters. The part sticking out looks to be about 40 meters. Or did you mean that it is 700 meters above the Valley floor?

Yeah, either way - a typo for length or grammar confusion to imply height above the valley floor. I happened to choose the latter.

Vertical is more the nighttime norm around this time of year. The best way I found to show this is using a composite of Google images showing both terrain and sky. The date/time range is very broad but to display the nominal MW orientation, the time stamp is Sep 9, 2:41am. Also, given the observation position, the field of view is constrained in Google Earth and GE fails to show the rock outcropping, but the lake and mountains recreate the APOD view pretty well. Interestingly, I can't get the MW to lean to the left as much as the APOD (for that view heading). That and funny constellation orientations I have to attribute that to distortion.
