Por motivos del COVID esta nebulosa esta hecha desde casa, resido en una ciudad con mucha contaminación lumínica. La nebulosa es IC 405, también conocida como Flaming, está en la constelación de Auriga. La estrella AE Auriga en su interior hace que la nebulosa de emisión brille. Su extensión es de 5 años-luz y dista de nosotros 1.500 años-luz.IIC 405, esta toda hecha desde casa, que al ser una ciudad grande tiene su aquel, si que es verdad que me ayudo en los últimos toques el gran maestro y gran amigo César Blanco..

Vela Nebula HOO_sml (Medium) by Simon Lewis, on Flickr

Vela Supernova Remnant - A Southern Gem

This huge bubble of Hydrogen and Oxygen is all that remains of a huge explosion that cast star material across vast areas of the southern sky some 11000 years ago. This single image represents only a small corner of this object which covers over 50 ly across. Lying some 800ly away from us it covers a large portion of our southern sky here in New Zealand.

NGC 7027, the pillow nebula.
NGC 7027 began its transformation approximately 600 years ago. This star at the end of its activity begins the most magnificent part of its existence, that is to say the transformation and the bursting of its outer layers! this phase is called: The Planetary Nebulae.
Its ejected layers, which can be seen in my image by circles held blue, are ionized and pushed by the combination of UV radiation and the pulsations of the fast and super fast winds of the white dwarf. These blue circles are caught by a super fast wind forming wings around the more famous shape.
This oval shape or envelope encloses a fairly bright torus, with an extremely bright part at the bottom of my photo.
And in the very center we can see the white dwarf, the core of the old star, which gives off an enormous amount of UV energy heating the surrounding dust and gases.

With a little bit of luck I took this picture of the crescent moon, Jupiter and Saturn above my private observatory between the clouds. 10 minutes after the sky was covered with clouds.

This is a very tiny part of the sky, precisely… it is just on the lower right side of the famous Pillars of Creation which are a small part in the center of the Eagle Nebula, M16.

Aproaching the great conjunction

Júpiter and Saturn in the same field of view of the telescope, 2 days before the great conjunction. Image in near IR light to be able to image the planets during the afternoon when they're still high over the horizon to minimize the turbulence. Image from Monterrey, Mexico on December 19th, 2020.

THE GREAT CONJUNCTION (2020-12-18)

This picture is a result of an international collaboration. Here, in Moldova, for the last few weeks sky is constantly clouded out and seems that it will stay this way for indefinite time. Depressing stuff, so I asked my good friend from sunny California to provide me with the materials she can shoot for this super-rare event. She did and I kept my part of bargain - processed it as good as I could!
Sky-Watcher Evostar 72ED + Barlow 3x + Canon 80D. Chose 1/60s and 0.6s shots. Sent both through PIPP. Stacked separately. Brought both into GIMP. Aligned. From 1/60s got the Jupiter alone. From normal 0.6s brought Saturn and Jupiter's moons. From brightened up 0.6s got Titan. Final touch in RawTherapee

Jupiter and Saturn on its way to the grand conjunction in December 21st. Taken on December 20th, 22:33ut. Had to reduce the focal length and just made it to fit in the frame of view. ( LX200ACF OTA, CGE mount, Reducer F6.3, ASI290mm Cmos, Astronomik LRGB filter set. )

One day before the great conjunction, on December 20th 2020. Image in near IR light from Monterrey, Mexico. 3 exposures combined to take this image. Jupiter with its moons, from left to right: Europa, Io, Ganymede and to the far right Calisto.

The Great Conjunction of Jupiter and Saturn

Resolution: 2200x1700:



The planets regularly appear to pass each other in the solar system, with the positions of Jupiter and Saturn being aligned in the sky about once every 20 years.

What makes this year’s spectacle so rare, then? It’s been nearly 400 years since the planets passed this close to each other in the sky, and nearly 800 years since the alignment of Saturn and Jupiter occurred at night, as it will for 2020, allowing nearly everyone around the world to witness this “great conjunction.”

The closest alignment will appear just a tenth of a degree apart and last for a few days. On the 21st, they will appear so close that a pinkie finger at arm’s length will easily cover both planets in the sky. The planets will be easy to see with the unaided eye by looking toward the southwest just after sunset. (text credits: Bill Keeter, nasa.gov)

The Great Conjunction of the Giants!!!

Some call it the star of Bethlehem but it really doesn't matter how you name it since such a rare event can only be a source of inspiration and that it happens at the end of such a weird year could be a good omen for the coming future.
The magicians followed it to find the one that would teach love to humanity, astronomers observe it to enhance our knowledge about the Cosmos, simple individuals to admire nature and become one with it.
The last time such an event happened, humanity was coming out from the medieval times by point the telescope to the sky and this time it struggles to find a break from the Covid pandemic that has devastated countries all over the planet.
I was very lucky to make this image today because it was cloudy all day and the forecast was for rain but somehow a gap made me running to the car and uphill to a beautiful location in Northern Greece.

Jupiter and Saturn’s great conjunction by Fotis Mavroudakis, on Flickr

Jupiter and Saturn’s great conjunction
2021 great conjunction of Jupiter and Saturn was highly conspicuous in the west just after sunset. But Since the prolonged low cloudscape in the region of northern Greece would leave no room for observation of the sky, I decided to literally climb above the clouds. At an altitude of about 1820 meters in the second highest peak of Paggaio mountain, the cloudscape transformed into a sea, leaving you to admire undistarbed the magnificent kissing of the planets.

Great conjunction with Ganymede in transit

Jupiter and Saturn Great Conjunction w/ Ganymede in transit by Tom Glenn, on Flickr

This image was captured on December 21, 2020 at 17:18 local time, in San Diego, CA (December 22, 2020, 01:18UT). Jupiter and Saturn are several hours past the moment of closest approach, and are separated by less than 7 arc minutes. All of the Galilean moons are visible, from left to right: Callisto, Io, Ganymede, and Europa. Notably, Ganymede is in transit across the face of Jupiter, located left of center in the NEB (North Equatorial Belt). The image is presented with a global gamma application, with no selective brightening of any region, which preserves the relative brightness of Jupiter and Saturn. Titan is just barely visible in this presentation, although several additional moons of Saturn are visible if the histogram is stretched further. The Cassini division is clearly visible in Saturn's rings.

Image was captured with a C9.25 Edge HD telescope and ASI183mm camera using a 742nm IR filter. 1000 frames of 35ms exposures were stacked (single exposure setting was used).
