Fascinating, Michael! Note that although the Great Red Spot is shrinking, its present color is quite saturated.

Good afternoon.

Photo taken on the island of São Miguel in the Azores, in the middle of the Atlantic Ocean. During the night I took a walk to the pond of fire. A crater of an island volcano that flees some of the city lights. No problem to appear in the forum.

The image is made by two exposures, one for the other stars for the background. I used a star tracker to take the picture of the stars in 240 seconds.
It had a color and shine treatment. I also increased the brightness of some stars.

Tulip Nebula (Sh-101) close-up in HSOrgb



Tulip Nebula (Sh-101) close-up in HSOrgb by Jose Carballada, on Flickr

The Tulip Nebula (Sharpless 101) is an emission nebula in Cygnus.
It lies at an approximate distance of 6,000 light years from Earth and has a linear diameter of about 70 light years.
It's apparent magnitude is 9.0 and it occupies an area of 16 x 9 arc minutes of apparent sky.

I used HSO palette with RGB stars. More than 33 hours of integration time, selecting only the best frames of the total valid frames captured (80%).

The Green Rim - Sunrise

Shot on a Fuji XT-3 and Canon 800mm F5.6L lens w/ 2xIII Teleconverter on a HOT july morning in central Texas

Notice the slight green at the top of the sun?
The "Green Rim" is a phenomena that occurs when the earths atmosphere acts as a lens and bends the light ever so slightly. Green light is refracted more strongly than red, resulting in different colored images of the sun become very slightly vertically separated. So as the Sun appears to rises in it develops a green edge on top and red on the bottom. This cannont be seen with the naked eye. I usualized a large Fstop and shutterspeed to capture the image safely.

North Amercia and Pelican Nebula:

It's an unused astrophotography summer if you not make at least one visit to the constellation Cygnus.
Used the 4inch APO Triplet in my little garden observatory combined with full frame DSLR. A huge emission
nebula - over 4 times the size of the full Moon, not far from the star Deneb:

Hi to all fellow sky observers, I hadn't been posting frequently but I have a good reason to send you this image of last weeks storm we had in Northern Greece in Halkidiki. As usually when I have indications for a local storm I take my gear and go as near as possible in order to capture the raw power of the lightings and also admire nature's raw power. This time a very unusual experience would happen the moment I approached the storm since I had never experienced anything close to what I and my wife would witness.

The first indication of a really powerful storm was the fact that flashes of lightning were falling non stop and without any time delay from one to the other and this was noticed from the car before we stopped and took the camera out. Even when going out of the car and observing the scenery from Monopigado, it was very clear that the storm would be very powerful and full of electrics so I immediately set up the camera and without trying to find a picturesque frame, I immediately started the acquisition of images. It would be only after two minutes when we realized that it is unsafe to stand in that location and this is all the time the camera had to capture just a few images before I just grabbed the tripod and even before the end of an exposure I just throw everything into the car and start running for our lives!

What would come next was a scene from a sci-fi movie since trying to return to our house, we found ourselves engulfed by the storm and at one point I noticed that in front of us debris would fly at speeds exceeding 100km/h. I could see tree branches with more than 3 inches diameter going ballistic and could easily break our car glasses threatening our lives. I looked at the mirror to see at the back and the same scenery there, by the way, we could easily see everything because of the lightings that were falling without breaks all around us so the night had turned into bright daylight.

I decided that traveling 10km into this storm would be a serious life-threatening condition so I returned to the initial observing location two kilometers away and thought I could find shelter by parking next to a building and find protection from the natural projectiles hitting the car. Anything coming off the land was a life-threatening bullet so we needed some kind of side protection and I found such between a building and a natural slope. Even parking there I had the car's strong lights on just to monitor any kind of landslide or water coming from the nearby hill which is not uncommon in conditions like these.

After we waited for about 25 minutes, we started driving back to our house and then we saw the disaster and devastation that was left behind. Trees were taken from the roots or were broken, landslides everywhere, branches coming up and also thick layers of pine trees with rocks and mud. When we reached our house, water was all over inside it and we spend the rest of the night cleaning it and considering the danger we faced getting injured or even dying.

The real blow came the next day when we woke up and saw on the news that in total seven people died in the most severe storm recorded. The nearby touristic locations were heavily damaged with no electricity for at least a day and even at the moment of writing, not all areas are back online.

I am observing storms from about 13 years now and I have never witnessed such an event in Greece and the meteorologists are discussing for a unique phenomenon happening in our country for the first time, the appearance of a super-cell storm. I believe this is part of climate change and are starting to see more violent weather in the form of heat waves, heavy rainfall and storms in the summer accompanied by forest fires as well.

The whole event has gained international attention since we had dead humans which came to Greece to relax and have some good summer time. Unfortunately, it was very bad timing for them and a combination of things lead to this disaster. I was very sad when I heard that humans had lost their lives and if human activity played a role in these extreme weather conditions, I believe I have a responsibility to alert others about our actions as civilization and stop destroying our planet. Nature has a unique way or returning back to us the bad we are making to her and the signs are all around us.
For your info, the first image is a total of only 50sec exposure and the second is just 15sec before I grabbed the tripod with an open shutter and threw everything in the car.

BEACH PARTY - FOR ONE!
Copyright: Alan C Tough

In order to capture this beautiful and spectacular display of noctilucent clouds on July 14, I headed down to a beach near Lossiemouth on the Moray Firth in Scotland. I was the only person there. Mind you, it was almost 2:30 a.m.!

I love your Milky Way image, PatrickWinkler! The image is wonderfully crisp and clear, and shows us the different "textures" (partly as a result of distance, and the absence or presence of a lot of dust) of the central Milky Way as seen from our perspective. The colors are gorgeous, too. Brilliant!

Partial Lunar Eclipse 16/17.07.2019.

I thought I had bad luck again. Because for almost 90 % of the eclipse time, I had a thick cloud cover over my head.
But thanks to that clouds I was able to shoot this photo - a natural HDR - because of the thin layer of clouds, bottom part of The Moon, which is not in the Earth shadow, is dimmer and similar in brightness to eclipsed part:)

Almost maximum phase of eclipse - 23:16 (63 %)

Thanks, I hope someday to be hung in the APOD walls!
