Twilight to me is a night sky in this case, late civil twilight. The 13000 foot high peaks at 130 miles out from my lens. This is a 2 second time exposure and it was very dark out. Once the sun goes down, there is still an hour and a half sky show through the three twilights. You just need a good tripod and time exposures to see the show sometimes. I have photographed many of these from start to finish. This week has been incredible.

Civil Twilight begins about 28 minutes before sunrise or ends 28 minutes after sunset. It is that period from when the sun is about 6 degrees below the horizon. On clear days you can do normal outside activities that require light. That solar elevation angle below the horizon defines each twilight phase. CIvil Twilight is by far the brightest of the three twilights.

Nautical Twilight starts when the sun is 12 degrees below the horizon technically. Both the Horizon AND brighter stars/planets are visible in this twilight. It is the “middle” of the three twilights. At the beginning of Nautical twilight, it’s about one hour to sunrise. Rule of thumb which varies with your position on the globe, is 28 minutes each twilight.

In Astronomical Twilight, If you live in the city, you have probably never noticed astronomic twilight. The are NO shimmers of daylight at the beginning of Astronomic Twilight a full hour and a half before sunrise. . Away from the lights of population centers, we see Astronomic Twilight regularly where there is just a slight greying of the black totally dark sky mid night. It gets as dark here on our ranch in remote northeastern Wyoming as the North Atlantic Ocean according to NASA.

Location: Bliss DInosaur Ranch, Wyoming/Montana borderlands.

Twilight Over the BigHorn Mountains is of course a night sky in late civil twilight. The 13000 foot high peaks at 130 miles out from my lens.

Last Day of Fall for the Big Horn Mountains

Last Day of Fall for the Big Horn Mountains

I took this Sept 30th the day before the October 1 storm came in so this was the Last Day of Fall for the BigHorn Mountains eastern front. You could feel the storm coming in. Everybody was buying snow shovels and salt at the local farm store.

Full Screen is obviously best…. 🙏

These 13,000 foot + peaks dominate the landscape near Clearmont Wyoming. The highway State 14/16 from Gillette to Sheridan Wyoming will present you with this view if you stop at the right spot :).

This is a composite of three images left/center/right carefully blended/stitched back together within the digital darkroom. As such is it ended up being 60×20 inches at full resolution 300 dpi so the original is a huge file reduced here for social media of course lolol.

Oct 1, the region got 4 – 12 inches of wet heavy sticky snow on trees fully leaved still from the 75 degrees the day before when I took this on Sept 30th.

I of course take photos of these hills all the time from my Ranch about 100 miles over my shoulder at this location. I get a little better resolution up here📸

Location: Somewhere near Clearmont, Sheridan County Wyoming.

This image of the 13K feet high Big Horn Mountains was taken on the highway near Clearmont. I wonder how they picked that name? Humm…

Irrigated fields, canals, ranches over 100 years old dominate this part of the state. This is a beautiful drive on state 14/16 going toward Sheridan if you get a chance to take it.
