| Occultation of Venus by the Moon |

ImageOccultation of Venus by the Moon by Joel Klinger, sur Flickr

The chase of the occultation of Venus by the Moon has been very tricky this morning!
There were plenty of clouds in the sky and on many places in Europe people have not been able to watch it.
Hopefully for me, clouds disappeared during 5 minutes just on time to see Venus coming out from behind the Moon.

The three shots gathered here were taken this morning from Tours (France) at respectively 10:51, 10:52 and 10:53 UTC.
Venus is not visible on the first picture, appearing on the second one and fully visible on the last shot (with a gibbous shape).
Witnessing the exit of Venus from behind the Moon with my eyes also has been a truly magical moment.

En el amanecer del día jueves 09 de noviembre del 2023, a las 05:11 AM hora local para el poblado de Tocuyito del Municipio Libertador, estado Carabobo, Venezuela. Observando en dirección hacia el Este, el estrecho acercamiento visual entre la pareja del planeta Venus (brillante con una magnitud de –4,4 bajo en la constelación de Virgo) y la Luna Menguante. Estuvieron a solo 1° o 2° de distancia visto desde América, dependiendo de su ubicación. Solo fue necesario apuntar nuestro telescopio 8” hacia el este y acercar un celular al ocular para realizar este hermoso registro donde bastó el buen pulso y contener la respiración para disfrutar de esta hermosa conjunción en esta grandiosa imagen.

Elephant Trunk Nebula (IC 1396)

"The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth. It is commonly called the Elephant's Trunk nebula because of its appearance at visible light wavelengths, where there is a dark patch with a bright, sinuous rim. The bright rim is the surface of the dense cloud that is being illuminated and ionized by a very bright, massive star (HD 206267). The entire IC 1396 region is ionized by the massive star, except for dense globules that can protect themselves from the star's harsh ultraviolet rays.

The Elephant's Trunk Nebula is now thought to be a site of star formation, containing several very young (less than 100,000 yr) stars that were discovered in infrared images in 2003. Two older (but still young, a couple of million years, by the standards of stars, which live for billions of years) stars are present in a small, circular cavity in the head of the globule. Winds from these young stars may have emptied the cavity.

The combined action of the light from the massive star ionizing and compressing the rim of the cloud, and the wind from the young stars shifting gas from the center outward lead to very high compression in the Elephant's Trunk Nebula. This pressure has triggered the current generation of protostars."

I wanted to capture the beauty of how dense stars become photographing into the core of the Milky Way, and the lovely balance of these dark nebula sort of “swimming” over a sea of stars. I took inspiration from what character this region of space might inspire as a snippet from a well-edited, deep, wide angle photography of the Milky Way.

Deep field image of Centaurus A and relativistic jets, (NGC5128)
  • Data and processing by: Amrit Prasad
  • Acquisition: My Bortle 6 backyard in Auckland, New Zealand
My most recently completed longer term project of the Centaurus A galaxy, NGC5128. This is a deep wide field with 120hours of exposure time. I find it to be an extremely fascinating object with the shell around it, the supermassive black hole, and the mysterious filaments and jet.

Due to the long exposure time, I've managed to capture filaments A, B, C and the Southern Jet which I've marked in the annotated copy, labelling also the nearby galaxies out of the NGC and PGC catalogues. Much to my surprise, there turned out to be around 80 known background galaxies within this area.

I captured all of this from my backyard with a Bortle 6 sky in Auckland, New Zealand between Feb 2022 and late April 2023. I have processed using both PixInsight and Photoshop.


Exposure detail total of 120 hours between:
  • 46hrs Ha, 3 minute exposures
  • 38hrs Luminance, 1 minute exposures
  • 36hrs RGB evenly distributed between each channel, 1 minute exposures
Equipment:
  • Telescope: Skywatcher Esprit 100
  • Location: Auckland, NZ. Bortle 6 zone
  • Camera : RisingCam IMX571, Gain 100/offset 50, -5c
  • Filters: Antlia 3nm Ha, Optolong L, RGB filters
  • Mount Skywatcher EQ6 Pro/290mm+60mm guide scope

Attached are a closer crop of the galaxy and the filments, a widefield copy, and a widefield annotated copy.

Desolate tree and Orion nebula.

In the photograph we can see the constellation of Orion along with its nebula of the same name, the Orion belt stands out with the brightest stars (Alnitak, Alnilam and Mintaka) next to a coigüe tree, typical of the temperate forests of southern Chili.

This tree appears dry and desolate due to the eruption of the Calbuco volcano in 2015. In this area (LLanquihue National Reserve) we can see a desert and desolate landscape due to the tongue of pyroplastic sediment fallen in the place.

Two-panel HDR mosaic of the southern region of the constellation of Orion from La Palma (Canary Islands, Spain). The pictures were taken a few days apart, just before and after the passage of the tropical substorm Hermine in late September 2022. The atmospheric conditions, with thin high clouds, almost entirely saturated in water vapour and under a strong skyglow, posed quite a challenge not only for capturing but also for processing this image.

However, I was fortunate enough to capture this gorgeous meteor with a debris bubble emerging from it in one of the exposures. The bubble moved away in subsequent exposures, as can be seen in the timelapse.

Modified Canon EOS 6D at ISO 1600 and a Samyang 135mm f/2 ED UMC lens, stopped down to f/2.8, sitting on an Astrotrac TX320X-AG tracking mount and a Sirui AM-284 tripod. All the processing workflow was made with PixInsight, including calibration and HDR integration for each panel, mosaic stitching, and postprocessing. The meteor subexposure was post-processed separately and then blended into the final image.

Heart and Soul Have you ever met a person with whom you share your heart and soul? I've met one, and since my hobby is astrophotography, I've decided to use it to create an unforgettable photo. This is a composition of two images: the wide starfield containing the Heart and Soul nebulae, and the flowery meadow where I am standing with my partner. The Heart and Soul Nebula are one of the first objects which started my adventure with astrophotography, and also one of the first ones that I pointed binoculars at while trying to spot them with my boyfriend. Nebulae are relatively dark, but the camera can reveal the true beauty of these objects. Stargazing together will always be romantic.

The starfield was stacked in Deep Sky Stacker, then processed in Siril, StarNet++, and Photoshop. The landscape was preprocessed in Photoshop and then combined with the starfield. Two gradients were added in order to simulate a low horizon hue, to make the composition look more realistic.

The Hyades 6-panel mosaic with Taurus Molecular Cloud Complex (TMC-1).

ImageThe Hyades and Space Dust

This is a 6-panel mosaic of the Hyades, showing a lot of space dust in the background. It totals 48 hours of exposure time. This dust, sometimes mistaken as IFN, actually comes from within our Milky Way galaxy and comes from the Taurus Molecular Cloud Complex (TMC-1) which is also visible around the Pleiades and the California Nebula.

The total size of this image is 118 MegaPixels. The image also shows Sh2-239 and NGC 1555 at the top, as well as the bright star Aldebaran.

The Hyades is the closest open cluster to Earth, located in Taurus just 153 light-years away. It is so huge that it is not possible to fit in the field of view of a telescope, hence the mosaic! I am very happy with how much dust I was able to bring out.

In the vast canvas of the cosmos lies the mesmerizing Cocoon Nebula, a celestial cradle where new stars are born. This image captures the essence of this stellar nursery, where clouds of gas and dust weave tales of creation. The Cocoon Nebula, is located approximately 4,000 light-years away in the Cygnus constellation. Its peculiar name comes from the dark band of dust that gives it the appearance of a cocoon, enveloping the nascent stars within.

The photo is a sum of about 19 hours of exposure time with:

Sirius stretched
This is a shot showing the colours of a twinkling Sirius, stretched out to make them move visible. To make this image I took a 1.6 second exposure of Sirius and during the exposure I moved the camera horizontally. This resulted in Sirius becoming a stretched-out line on the final image. I then edited this in Photoshop to stretch it out to the size of the full picture, thereby making the many different colours of the twinkling more visible. What I find fascinating about this method is not only the striking image it creates but the many different colours that can be seen. More and more tones can be seen as you zoom into the image. I used a Canon 550D DSLR with 300mm lens at f/5.6, ISO-800 on a static tripod. Shot taken on 7 November 2023.
