Hundreds of Native American ruins and endless quantities of rock art lie within the new Bears Ears National Monument in southeastern Utah. The night skies here are about as dark as they can be in North America.
This little granary was built by Ancestral Puebloans about 1000 years ago before they abandoned the region in the 1300s. The night sky then probably looks about as it does now.
About 30 minutes of photos were captured near the end of astronomical twilight. Weak sunlight and a thin crescent moon illuminated the structure.
President Trump has call for a re-evaluation of 26 National Monuments, the decision to keep or rescind the protections the National Monument status provides will be announced June 10, 2017.

Here is a new image of M89, it's one of the deepest images to date of this rarely imaged galaxy, Some of the outer shell may be newly discovered. There are so many galaxies in this image. Being a boring elliptical is probably why no one seems to image it, it's far from boring!

Shapley 1 is a beautiful but rather small ring Planetary Nebula in Norma, it is a torus or ring rather than a bubble or hourglass shape more typical of planetary nebulae. The inner bright "spare tyre" ring is just 75" in diameter, the gossamer glowing halo outside this is 1.8' in diameter and the long 32.5 hr total exposure time has revealed a recently discovered ring structure around the periphery, which takes the nebula's size out to nearly 2.5' in diameter. The first reference to this thin faint outer OIII ring, known as a bow shock, appeared in the below 2011 paper, visible in stretched and contrast enhanced deep OIII data taken using the 3.6m NTT at La Silla.
Photographed in the Black Forest National Park, Germany.
200 images (20 sec exposures) were combined for the star trails. Two additional images for the illumination of the tree in the background and the broken off branch in the foreground were added for the final result

At the southern end of the large emission nebula, RCW 113, in Scorpius is the dark nebula, SL17. As can be appreciated from its shape, it is often called the Wolf Head nebula. Please enjoy this HaGB image.

Small and Large Magellanic Clouds Touching The Horizon
Explanation:Few days ago I've returned from a astrophotography trip throughout Atacama Desert. At one of the desert altiplanos I've managed to capture this unusual scene. The two Magellanic Clouds separated by an inactive vulcano (Chiliques). It's possible to glimpse 47 Tucanae and the SLM reflected in the water.
Living in the southern hemisphere that was the first time I saw both Clouds so low in the horizon at the same time.
Not only is the composition superb, but I love the subtle colors, too.

Hello,
I filmed the passage over France (Tours) Saturday night, about 20 min
after launch:

You can see the Dragon, stage 2, solar panel covers plus a nice
surprise I discovered during processing: several fast ejections of
material, probably from thrusters! (highlighted at the end of the video)

Saturn - June 7th, 05:29ut.

Saturn - June 7th, 05:29ut. Under slight above average conditions. Now within six days of opposition.
This is a small section of a focus check frame from a 1 meter telescope of M3 globular cluster in Canes Venatici at ~12x scale. We see part of the core extending out a short distance. This is one example of how stars are resolved through telescope optics and quantized digitally on a CCD sensor. These are the raw dirty details of how the light from distant globular cluster M3 looks close up to the camera.
If you stand about 6 feet away from your monitor, your eyes and brain will start to smooth out the pixelation making the image look continuous and recognizable. I thought it looked cool.
NGC4631, known as the whale galaxy in Canes Venatici is a beautiful edge on spiral estimated 25 Million light years distant. Pal NGC4627 hangs close. In this LRGB image, (H2) star forming regions are visible along with dust, and and other clumpy regions. This was captured with a 10" corrected cassegrain amateur telescope and CCD camera and appears about 15 arc minutes by 3 arc minutes on the sky. This image was built from 3.5 hrs of luminance, and 2 hrs of color frame integration time.

Here is a new 2 pane mosaic image of NGC 4151 and 4145 in Canes Venatici. This is one of the deepest and highest resolution images to date of this pair of galaxies by an amateur. Notice the 2 small galaxies next to NGC 4151(Left galaxy) both have tidal tail features.

Explanation:Image taken on June 9th, at 5:08 AM. Certainly one of the most fun photos to do! After planning and replanning, you just wait for the right moment and make the image. Right? Not at all! Composing the alignment between the Moon and the Christ has turned into a fun run-off in the final moments of closeness. "Still not aligned, run with the tripod 10 meters to the side," is it aligned?? No! "Run with tripod on the other side" was it? Almost!! More to the left!!
Explanation: The strawberry moon, also called the June Harvest moon, is a full moon (here only 99% Waning Gibbous, due to bad weather) that is at its apogee (point of its elliptical orbit where the moon is at its farthest away from the Earth). In other terms, it is a micro-moon (about 14% smaller and 30% dimmer than a supermoon). The moon crosses its apogee point once a month, however since its phase cycle and its orbit are not in sync, micro-moons and super-moons only occur occasionally. When the moon is rising, the loupe effect of the Earth's atmosphere makes it look bigger and deformed, and you can't really tell if it is really smaller or bigger than usual. The moon was supposed to rise at 10:26pm on June 10th, and this picture is taken at 10:27pm, so you can see that this loupe effect makes us see the moon rise well before it actually does. It a bit like when you can see a coin in a tank full of water whereas you are away from the edge.
The name strawberry moon comes from what the Algonquin tribes (Canada) saw as a signal to gather ripening fruit. In Europe, we used to call it the Full rose moon, or the Honey moon. The name is also probably due to the special slightly magenta color given by the late twilight, whereas the night has already fallen in the winter and we see it more orange or yellow.
