Hi everyone,

The Soul Nebula IC1848 ( Westerhout 5 )
The open cluster of stars, surrounded by cloud of dust and gas creating a beautiful Soul in the sky.
This iconic nebula located in Cassiopea, easier to photograph in narrowband.
6500 light years away, the Soul Nebula filled with several open clusters of stars and a large star forming region.
The colorful rendition when combined in SHO Hubble palette with the Oiii cores in blue and surrounded by stronger Ha/Sii.
Visible for most part of the year from the northern hemisphere, imaging the nebula is a bit challenging from the Equator since its quite low on the horizon.

LBN 673 Heart of the Soul Nebula

Deep inside the Soul Nebula is the star forming complex of IC 1871 & LBN 673. Rich with emission and dark nebula.

IC348 and Barnard 3: An Angel vs Demon in HaLRGB

The following image of IC348 and Barnard 3 was taken from Rockwood Texas at Starfront Remote Observatories hosting my Epsilon 160ED and imaging equipment over multiple nights between 10/21/24 and 10/28/24.

IC 348 is an open cluster located in the constellation Perseus. It is a part of the larger Perseus molecular cloud complex and is about 3,200 light-years away from Earth. It is brightly illuminated and nearly obscured by Atik in this image. To the right of the field of view is Barnard 3, sitting beautifully against a background of red Ha emission that provides interesting contrast and detail to the foreground dark clouds.

Overall, the bright Atik with its bright halo and nearby IC348 mimic an Angelic structure against the demonic colors of the red / dark clouds of Barnard 3, hence the title. I will credit that comparison to my wife who thought of it when she saw it first and now I can't unsee it.

C/2023 A3 Approaching Milky Way by Michele Guzzini, su Flickr

I thought I had said goodbye to it, but here it is again! The comet C/2023 A3 is moving away from Earth and is "crossing," from our perspective, the Milky Way in the constellation Ophiuchus. It's not visible to the naked eye, but in photos, it's still a beautiful sight.

Touching Antares in the south of Chile

The Vicente Pérez Rosales National Park, from the Petrohué sector, was originally a cattle trail through which animals were moved between Lake Todos los Santos and Lake Llanquihue, via the Desolación pass. This route allows you to travel through dramatic changes in the landscape: from volcanic slag heaps to dense nothofagus forests, all nuanced by excellent views of the Tronador and Osorno volcanoes, La Picada hill and Todos Los Santos lake.

The place name desolation perhaps refers to the desert landscape of the portezuelo, which, devoid of all trees, has been covered by volcanic ash.

In the photograph we can see how this desolate tree seeks to reach the sky touching the constellation of Scorpio, specifically Antares, which in detail is the cloud formation of Rho Ophiuchi.

Title: The Helium Sun
Exposure: stack of 40 scans, taken in roughly an hour, around 2024-11-06T11-00-00Z

I photographed the Sun, using a spectroheliograph, in the spectral line of Helium I D3. I applied quite some math to amplify the helium signal and render an image similar to what we are used to for hydrogen and/or calcium, instead of the delta shown often with data like ChroTel. An extra, the relatively bright triangle in the lower half is visible as a dark feature in the coronal image of AIA 211.

So this is the Sun, in the light of the death breath of main sequence stars.

Ring of fire halo over Easter Island

Easter Island / Rapa Nui, Chile

Nikon Z7ii (unmodified) + Tamron 35-150mm f2-2.8
ISO 50, f/2.2, 55mm, 1/100 s

This picture was photographed on the Oct 2024 annular solar eclipse at Easter Island. A few minutes after the "Ring of Fire" eclipse climax, I was able to move and get the composition of the sun over one of the Moai's.

The result was a 22 degree solar halo over the Moai's "Pukao", a topknot hat-like structure. It was amazing to experience, at the same time, a rare astronomical and uncommon atmospheric optical event at one of the most enigmatic places in the world.
