COAL SACK Northern Side - Dark Cloud in Crux

The Coal Sack nebula is one of the most prominent dark nebulas in the sky. Under dark skies it is easily visible due to contrast with the dense star background of the southern Milky Way. Its main area is located in Crux, but spreads also into the constellations of Centaurus and Musca.
The image is showing the north part of the Coal Sack. The bright and relative small nebula in the upper left is called RCW 71 which is ionized by the 0.95 V star also known as HD 311999, center top the popular Jewel Box or NGC 4755 and, to the upper right open galaxy cluster NGC 4852 with 12 arc minutes in diameter and 8.9 magnitude.

This "Firefall" effect is caused by the setting sun lighting up Horsetail Falls in Yosemite Valley. It appears in early February when enough water is flowing and the sky is clear at sunset. It should also appear in the fall when the Sun's declination is similar, but seldom is there enough water flowing in the fall. It is named after the original Yosemite Firefall which was created by pushing burning embers off Glacier Point. That firefall was stopped in 1968 to prevent the crowds, traffic jams, and damage to the meadows around Camp Curry. The first published photos of the effect were by Galen Rowell in 1973. The event has now become a popular tourist event with small crowds and traffic control in place.

The Firefall is visible from many locations in Yosemite Valley, but conditions must be good to see the dramatic effect. The Sun must set in clear skies and the falls must have sufficient water.

Description:
Located about 180,000 light-years away, in the constellation of Dorado The Tarantula Nebula, is part of the Great Magellanic Cloud, satellite galaxy of the Milky Way. It is a region of intense star formation, and has a diameter that exceeds 1000 light-years. The star cluster R136 in the center of the nebula produces much of the energy that makes the nebula visible. It is the largest known emission nebula. It is about 100 times as far away as the Great Orion Nebula, and if it were In the same distance that Orion is of us (1500 Light Years) would cover an area of ​​60 full moons, being able to cause shadows (Wikipedia) Initially it was considered a star, however in 1971 Nicolas Louis de Lacaille identified it like a nebula.

During a thunderstorm I shot some long exposures and caught this giant ball lightning (I guess). This is not a stack of images, it's just a 30 seconds exposure. All the lightings occurred simultaneously. I've never seen this before. I think I was lucky capturing this moment.

Moonrise on Hármashatár-hegy
Copyright: György Soponyai

Hármashatár-hegy is a mountain in the city of Budapest, Hungary. Its name comes from the fact that the borders of 3 cities (Buda, Óbuda and Pesthidegkút) met at this point in the 19th century. Today these cities have merged into Budapest but the name of the mountain remained unchanged. The top of the mountain is located at 496 meters above sea level.
