NGC 362 - The forgotten Cluster

NGC 362 is the “other” brilliant globular cluster in Tucana, located on the north-east border of the Small Magellanic Cloud. It was discovered by James Dunlop on August 1, 1826 and cataloged by him as No. 62 of his catalog.

In the late 1980s, NGC 362 was compared to the otherwise similar globular NGC 288, and it was found that this cluster was about 3 billion years younger. This because of differences in the color-magnitude diagrams: the so-called Horizontal Branch of NGC 362 is redder, and the turnoff point of the main sequence (hottest/bluest/most massive main sequence stars) is bluer (and brighter).

Although both bright (mag 6.6) and large (14 arcmin), NGC 362 is often overlooked because it’s in the same area of sky as its brilliant big cousin, 47 Tucanae, (NGC104). However NGC 362 has a lot of appeal in its own right, as a compact globular cluster easily visible in small scopes. With large apertures the globular is more resolved, revealing many stars tight to the core. (*)

What are these 2 bright bulbs above the tree? Last year, you could observe beautiful Saturn (smaller) and Jupiter (bigger) close to the Milky Way core.

Enjoy the view of our beautiful Czech land with Slovak mountains in the background. After month of cloudy nights, we had a clear night with lots of fog in the lowlands blocking significant ammount of light pollution. You can still see few clouds passing by before they overflow the whole sky again

Comet C/2020 F3 Neowise over Žalostinná Copyright: Pavel Váňa
July of 2020 was the month when we forgot anything about SARS-COV 2019 because of this beaufitul comet. Every astronomer living in north hemisphere on Earth was travelling to his favorite spot to capture these beautiful moments.
That year I found a beautiful spot near my home which is called Žalostinná which is located in Slovakia near Czech borders.
21st July 2020 - that night had some magical spirit. Air was so clean, but in the long distance there were some thunderstorms so we saw flashes from lightning over sky, maybe thanks to these storms you can see some beautiful structures of airglow.
Pano was made of 40 single shots each was exposed for 13 seconds with ISO 4000, Canon EOS 6D mod., Sigma Art 24 mm f/1.4@2.2.

Aristoteles and Eudoxus craters are located on the Southern edge of the Luna Mare Frigoris - The Sea of Cold, which in terms of Mare descriptive Selenography is somewhat vaguely defined. Aristoteles lies east of the Montes Alpes and to the north of the Montes Caucasus which are at the foot of the image. It is an impact crater of approximately 87kms in diameter with a depth of 3700.0m. Its relatively shallow depth for a crater of such diameter may indicate post impact lava flooding. Unlike most examples of complex craters the absence of any high central mountain could be an indication that such an event did occur leaving only the tops of the impactor peaks visible. The almost complete collapse of the crater South-Western wall is sharply seen in this image along with well defined terraces to the East bordering the earlier formed Mitchell crater. The South Wall of Aristoteles has also been “pushed in” by ejecta from the impactor that later produced Eudoxus crater.
Eudoxus crater is 67km in diameter and around 3.4km in depth, as with its neighbour it lacks a central peak and contains only a group of low hills scattered about the central area. The terraced structure of the walls are clearly visible.

Water World - Iguazu Falls

The Milky Way cloud crosses the Iguazu Falls skies over the Santa Maria jump.
In this panoramic shot we can easily identify some deep sky objects characteristic of the southern hemisphere, such as the Eta Carinae nebulae, Running Chicken Nebula, Coalsack Nebula, as well as the southern cross.
It is interesting to have this view of the universe from the Iguaçu Falls, when man seeks water on other planets, perhaps thinking of a future need to abandon our planet due to the devastation caused by population growth and industries.

Matterhorn

360°panoramic view (crop around 270°) consisting of 4 shots + one for the high lights; from the left: the Gorner Observatory, Monte Rosa, Mars, Breithorn, Saturn, Jupiter, the Moon, the Matterhorn and below the Gorner glacier. 
Sony A6600 + Samyang 8mm f2.8 FisheyeI thought about the title, then, the photoshop project and the backup folder were called Matterhorn, the name across the border to define the Matterhorn and nothing... That was fine.The name of this mountain is epic, but even more epic is its view from Zermatt, the beautiful Swiss town from which the little train that ends at the Gorner Observatory departs.As soon as you see the Matterhorn appear, you immediately realize that you are faced with something to which you must pay much, much respect, as every element of nature deserves, especially the great mountains that have written the history of mountaineering. 4478 meters of magic.
When I arrived at the Gornergrat I realized that the Matterhorn was just one of the incredible elements that characterize this area, the area is beautiful, the glacier that descends from the ridge of Monte Rosa, the alpine lakes, the atmosphere there is unique.Definitely one of the most beautiful stages of the 30 days spent in Switzerland, wonderful land that has changed a lot my way of seeing life.the 11.302px long side file is perfect, and it will surely end up in my room).

360°degrees panorama with Jupiter, Saturn, Milkyway, and an extraordinary cliff from Italy. This photo has also been awarded in many international conferences, exhibited in the Royal Museum of London. Of course, a big part of the merit is of the place.
This extraordinary location is perfect for photographing the milky way, Sardinia is one of the most beautiful islands in the world, and at night it really becomes magic.

STORY:

Santa Maria Jump - Iguazu Falls

Photographing Iguazu Falls at night has always been one of my priority projects. For that, it was necessary to obtain a special authorization from the environmental agency responsible for national parks in Brazil. Finally, in early 2021, I got this authorization and set out to put my plan into practice.
I spent 4 days inside the Iguaçu National Park with exclusive access at night to the Falls for me and my students. The first challenge is to walk around the park at night knowing that several jaguars reside there, which are frequently seen by employees and tourists. In the area closest to the main waterfalls, the big challenge is to make long exposure images with the strong water spray from the more than 1.5 million liters per second that fall through the waterfalls. Working with exposure times longer than 10 or 15 seconds became an almost impossible task and the lens was never dry.
In this image we have one of the main waterfalls of the Iguazu Falls complex, the Santa Maria Jump. Immediately over it we can see Jupiter and Saturn and the zodiacal light illuminating the horizon. Further up there is the Milky Way Core with a level of detail and a very good density, taking into account that the capture had an exposure time of only 10 seconds. We can also identify some of the main emission nebulae present in this region of the sky.

HICKSON 44
The four prominent galaxies seen in this field are one of the groups called Hickson ... in this case Hickson 44, about 100 million light-years away from the constellation Leo. The two spiral galaxies in the center of the image are edge-to-edge NGC 3190 with its distinctive warped dust alleys and S-shaped NGC 3187. Together with the luminous elliptical, NGC 3193 on the right, they are also known as Arp 316 The spiral in the upper left corner is NGC 3185, the fourth member of the Hickson group. Like other galaxies in the Hickson groups, these show signs of distortion and enhanced star formation, evidence of a gravitational tug-of-war that will eventually result in galaxy mergers on a cosmic time scale. The merging process is now understood to be a normal part of the evolution of galaxies, including our own Milky Way. For the scale, NGC 3190 is approximately 75,000 light-years in diameter at the estimated distance of Hickson 44.
