Perfect Night
The Perfect Kiva in Bullet Canyon, a tributary of the Grand Gulch.
This is an amazing area within the new Bears Ears National Monument. This region has plethora of ancient sites and intensely dark skies. The depth of the canyon shields one from the light pollution sometimes visible on the mesa top from the small towns of Bluff and Blanding.

This kiva is about 7 miles from the trailhead. Perhaps around 800 years old and was probably used as a subterranean ceremonial chamber by the ancestors of the moderne Pueblo Indians lived here hundreds of years before. Notice the ladder protruding from the opening.

It may have been a trick of my mind but I thought I could see my shadow cast by the light of the Milky Way. The dark skies in this Bear Ears National Monument are unparalleled any where in the lower 48 states. These skies are a unique resource that need to be preserved.

The monument is a precious area rich in archeology and paleontology that is currently under review by the current administration to determine if the area is worth protecting and if the protective status of the monument should be rescinded.

To accomplish my APOD project, I've flown from Italy (Rome) to Sahara desert where i've reached Ksar Ghilane oasis. I've started my solitary walk with my backpack to the desert dunes soon after midnight, in order to find the best sky conditions for my project. After 1km walking, i've found a good area and mounted my stuff: Canon 5D mark4, Canon 16-35 f2.8 lenses, Manfrotto tripod 190 series, Skywatcher Star Adventurer electronic mount. I've shot 3 frames for the Milky Way, then i took a photo of myself and a long exposure for the desert landscape during the night. Being there was absolutely amazing. Still can't describe what I felt in that magic atmosphere surrounded by peaceful silence and gently wind. I really hope to earn this award. That would be my dream.
Thanks for reading.
Regards.

I love your image, AlessandroCantarelli.

I love the composition and the beautiful resolution, but most of all, and as a Color Commentator, I love your splendid portrait and the splendid colors of the Milky Way.

Description:

This is the first photo from South Africa that I wanted to present. Probably the best photo I have ever done in my entire career. Regardless of the comments (welcome as always), I am extremely satisfied with this picture. Why?

Since I remember, I always dreamed of taking a picture of this object. This is one of the icons of the southern sky and in my opinion the most beautiful and colorful object seen from Earth. When I was working on source material, I had to keep my imagination tethered, because in this picture the color is coming out practically everywhere. If anyone thinks that these reds are some kind of amp-glow or gradients, then I want to calm down - there is no gram of such defects there. The color is evenly balanced and what's coming out there are elements of the missing part of the Rho Ophiuchi complex that spills over an area of ​​more than 5 degrees in the constellation of the Ophiuchi - just 1 degree from the binary star system ρ Ophiuchi (two blue subgigants whose 3.1 angle separation is possible for visual observation).

The brightest and most yellow star is of course Antares. In the naked eye she looks unnaturally. It is very yellow, which reminds of the suspended Chinese lantern. You can not go wrong with any other star. This color is probably due to the obscuration of the star through dust clouds (in the observation line).

This hot (13-22 K.) dust and gas complex has a mass of 3,000 times our sun. There are probably many new stars out there, as we are already seeing a lot of young ones (100 thousand years - 1 million years old).

Camera exposure ZWO ASI071MCC - 3.5 hours, APO71Q f4.9, iOptron CEM25-EC, South Africa (taken near SALT observatory, Sutherland)

It is difficult to tear your eyes off this starfield. Real genesis.

And I just checked one item from my private "bucket list". Whew ...

I love your portrait of M33, Jerry. I love how you show us the low surface brightness of the old yellow population, and I love how you show us the small size of the little white nucleus. And I love how you show us the young blue stars as grains of salt sprinkled over the galaxy.
