Death Valley National Park, an international dark-sky park certified by International Dark Sky Association.
The only light region comes from 200km away Las Vegas.
Also the thin clouds make Mars and Saturn scattered to be much larger and brighter.

Shot in Death Valley dark-sky park.
At this hottest, lowest, driest place, we can also feel darkest night sky to show milky way with much detail.

A star trails image, I just can't do enough of them, but this time using a telephoto lens at 150mm.
I'd been sat on the beach looking at the island a kilometre out and decided it may be nice to frame it up and see if I could capture the stars emerging from atmospheric extinction. When I went back on the beach later that evening, there was a fair bit of cloud about and I thought that I would get nothing of merit. I grabbed 40 mins of data anyway (There are a lot worse things to do that to lay on a beach watching the stars after all).
What came out was this shot. I don't know why, but it's my favourite to date - just something about the clouds and the merged wave tops being in harmony, and where did that lilac sky come from?! Other than stacking, and some gentle adjustments, it's how it came off the camera.

Mercury transit in H alpha from the University Observatory in Munich, Germany. The image was taken with a 900mm refractor and a Canon 700D.
The video shows the double transit, plus another double transit with an unexpected guest:

10 minutes after the transit of the ISS, I was under a thick layer of high clouds! I had to change the camera parameters even at the last seconds, because of the clouds that changed the brightness very quickly.
According to specialists, the plane is a Pilatus PC12. Altitude was about 500m, distance to me about 1000m (there is a small airport 2km north).

Yesterday I observed and photographed the transit of the Mercury in front of the Sun however the clouds and the terrible seeing prevented taking my expected photo sequence in every 10 minutes. However there were clear moments in the afternoon when the Solar disk could be photographed with my Dobsonian telescope.
Four years ago I also took photos about the Venus transit and last March I was amongst the lucky ones who could see the total Solar Eclipse from the Spitzbergen -- the biggest adventure of my life..
As I was using different cameras and lens I re-scaled the three photos. With the same Solar size the visible size of the inner planets and the Moon can be compared:
