Abell 35 (Sh2-313)

What a strange looking nebula it is! Apart from the bow shock effect which gives its peculiar appearance, the use of a dynamic narrowband combination and a few hours of processing of Ha-Oiii-Sii has brought a more dramatic and colorful view of this magnificent star breath!

This photo presents the evening visibility of the innermost planet of our Solar System on the Western Sky captured near Mogyoród, Hungary. The pictures were taken at the time when the Sun was located exactly ten degrees below the horizon.
I slightly had to enhance the brightness of some later planetary "dots" in order to make it more prominent.

The previous weeks I was thinking a lot about how to add the words "Deacon" and "Taylor" to the photo title: Mercury/May/Deacon/Taylor -- the whole Queen band, but that would be a dummy joke..

STARBURST GALAXY IN COLUMBA

NGC 1808 is barred spiral galaxy located in the southern constellation of Columba. It was discovered by Scottish astronomer James Dunlop from Australia, who described it as a "faint nebula". It is a barred spiral with marked similarities to our home Milky Way Galaxy. NGC 1808 is distinguished by a peculiar nucleus, an unusually warped disk, and strange flows of hydrogen gas out from the central regions. Amidst all of this, because NGC 1808 is undergoing with intense star formation activity it has been deemed a starburst galaxy. NGC 1808 is relatively close to our Milky Way, and spans in about 35,000 light-years.

Some faint galaxies from the PCG catalogue were captured in the image

The Bubble Nebula
53 Hours of SHO and RGB Stars !

This project was in my bucket list for a long time, mainly because the Bubble was the reason I started with astrophotography.
Took to complete about 3 month mostly because of the weather, and oh boy I'm happy with this final version

"Nox Atacama"
360° panoramic view of Toconao Canyon in the Atacama Desert. 18 shots at 14mm f2.8 for 30 seconds each. September 2019.
From the left, the Clouds of Magellan, the Milky Way with Jupiter near the center of the core, my figure, the town of San Pedro of Atacama in the middle of the desert (it is not sea, it is desert).
Well, well, here there is not so much to say eh ... In the sense, this is the best sky in the world, I could close the story here. That night was completely improvised among other things...
We found ourselves in this rocky area while we were aiming to reach the lagoons of the south of the Salar de Atacama; the roads, believe me, are endless down there. Here in Europe if you see a mountain far away you know it can be 50-100km maximum, when you see a mountain of 5000 meters in a desert with 5% humidity it is a 7 hour drive.
When we explored these canyons I realized that I could combine something good, the big problem was the heights: the side embankments (shooting from inside, on the river bed) were very high, the Great Magellanic Cloud rose exactly when Antares set...
In the end I preferred to sacrifice a bit Antares to have Magellan completely out of the horizon. It was a bit difficult choice, but being on the other side of the world I thought well, when it happens again.
The night was spectacular, zero humidity (around 7%), no clouds, and a powerful red airglow that invaded the entire lower part of the sky, an incredible spectacle.

"MOAB"
From the left: the Tre Cime di Lavaredo (unfortunately covered by the mountain on the right side, even if it looks like a cut, it's a precise 360 degrees and the rock covered right there), Mount Sorapis, the Moon in conjunction with Venus, a strong Zodiacal Light, Auronzo di Cadore, myself, the Cadini di Misurina, the Galactic Arc with Orion and the Pleiades on the bottom and a tide, but really a tide of Airglow.

Milky Way and airglow from Czech Republic

Location: Staré Hamry, Czech Republic

After observing the night sky for the public, which takes place throughout the year in our Dark Sky Beskydy - Dark Sky Park in the Czech Republic, for which I work, I went to a nearby meadow and photographed this panorama. Already in the preview in the camera, I saw signs of airglow, but only during the subsequent processing did a lot of airglow come out and this is my first major experience with this phenomenon.
Although there is no astronomical night at this time, the sky was beautiful, the night was calm and windless.

Milky Way and airglow by Robin Onderka, on Flickr

Milky Way from Monoceros to Gemini

A 21°x42° view of the of the Milky Way in constellation Monoceros, Orion and Gemini was calculated with a resolution of 10 arcsec/pixel. Full views below are down scaled by factor 19, larger version can be loaded by clicking on the image, full resolution pictures (using a Javascript viewer), selected details and further information can be found on my homepage


H-alpha is mapped to red, blue continuum is mapped to green and red continuum is mapped to blue. Stars in the continuum channels are partly subtracted. That region does not contain much reflection nebule. Compared to the pictures from the Orion region I posted two weeks ago it looks quite boring.


A false color image from H-alpha data.


A true color view where red component shows red continuum including some (but reduced) H-alpha, green continuum is mapped to green and blue continuum is mapped to blue. Stars are not subtracted such that dark nebula become visible (as dark nebulae. In the first mage it can be seen that many of them are not truly dark)
