Wow, that's amazing, Matt Dieterich! Is that a bipolar outflow of ionized hydrogen from the center of NGC 55?

NGC 55 looks like relatively smallish galaxy, and its (somewhat faint) yellowish bulge appears to be "pushed to one side". But in your image, the outflow appears to originate from the exact center of the galaxy, as if it emerges from a perfectly centrally located black hole with an accretion disk, or, alternatively, a centrally placed large site of star formation with accompanying supernovas. The Wikipedia article does indeed show us a large site of star formation at the center of NGC 55.

I don't know what your image is showing us, but it sure is fascinating!

Tarantula Nebula in Duo Narroband OSC, 200mm Newtonian. Reprocessed, wider version

This is the third production of mine with the new Newtonian Astrograph described in the specifications.
It´s been a quite hard learning curve, but I am proud of my progress so far.

This is a dancing sprite event that I captured from Puerto Rico. A dancing sprite event is defined as multiple sprites appearing in a sequence during the discharge of some powerful positive cloud to ground lightning strokes. In this event, the lightning, and the resulting sprites, were heading towards the location of my camera. Usually, these dancing sprites will appear side by side, or horizontal, but in this event they were vertical. The vertical capture means that the flash sequence of this very powerful lightning stroke was heading in the direction of my camera. The first sprite was low, so that means the sprite was further away from my camera, and then the proceeding sprites were appearing higher up, which means they were getting closer to my camera's location. This is rare and has never been documented before.

Cosmic clouds form fantastic shapes in the central regions of emission nebula IC 1805. The clouds are sculpted by stellar winds and radiation from massive hot stars in the nebula's newborn star cluster, Melotte 15. The cluster stars (which are at least 1.5 million years old) are toward the right in this colorful skyscape, along with dark dust clouds in silhouette against glowing atomic gas. A composite of narrowband and broadband telescopic images, the view spans about 30 light-years and includes emission from ionized hydrogen, sulfur, and oxygen atoms mapped to green, red, and blue hues in the popular Hubble Palette. Took just over 2 months to complete this image.

Tried out a new processing workflow which was meant bring more emphasis on the dark and central gas structures while keeping the highlights toned down. I made a few variants of the Hubble palette but eventually settled on the good ol' traditional Hubble Palette colour grading. I finally created my own Luminance layering technique, which also brought out the sharp and cripsy details in the dark nebula region. The use of good masks were crucial for selective sharpening of the Luminance layer while the final layering was done traditionally in Photoshop CS 6.

NGC 7090 - small, but beautiful



More infos: https://www.skypixels.at/ngc7090_info.html

NGC 7090 is a barred spiral galaxy in the constellation Indus in the southern sky and was discovered in 1834 by the English astronomer John Herschel. It has an apparent magnitude of +10.7 mag and an angular extent of 7.8' × 1.3'. We see it exactly in edge-on position, the spiral arms appear here as dark dusty clouds, illuminated by the bright centre of the galaxy. What I like about this image is the apparent outline of the bright foreground stars, which really bring out the galaxy.

Dear Professor Robert J. Nemiroff, dear Professor Jerry T. Bonnell,

I hope you are both well.

By means of this email, I would like to submit an image for the NASA Astronomy Picture of the Day (APOD): https://flic.kr/p/2o2act6
The photo was taken on 13 December 2020, 07:35 am CET, on the Pont des Arts, overlooking the Pont Neuf and Ile de la Cite, 75006 Paris, France. The photo was taken before the sunrise, which was scheduled at 08:36 am on 13 December 2020.

I read and re read the NASA article "What's Up - December 2020", and from what Mr. Tony Greicius writes, I am extrapolating that in this photograph, I was able to magically capture 4 planets at once: Jupiter and Saturn (in the top left, closer in the sky than they have appeared in 2 decades) and the old crescent Moon and the planet Venus (on the top right).

Doing more background research I came across another photograph in the NASA Archive for Astronomy Picture of the Day listed on 14 November 2020, that is similar to mine, taken on 13 December 2020. It is the image labelled "Venus, Mercury and the Waning Moon": https://apod.nasa.gov/apod/ap201114.html

Is it possible that my photo, in the quality in which it is attached, could be enhanced?

Is it also possible that it could be labeled as "citizen science"?

Best regards,

Mascha Samkova

Eclipse During Eclipse

On the evening of 2022-11-08 I successfully observed and photographed the total Lunar eclipse from the capital of Japan.
This eclipse had a once-in-a-lifetime speciality as during the event the Moon was conjugating with planet Uranus. And by viewing it in East-Asia, the Moon passed in front of the planet, so there was a Uranus-eclipse by the eclipsed Moon.
The photos were taken in every 15 minutes.

Orion Nebula (M42) and the Running Man Nebula (NGC1977) Newtonian Astrograph version

Still in the process of discovering the best workflow for this fast newtonian.
I´ve tried since I started in astrophotography to achieve a decent M42. Well, the term "decent" has different meanings for each one.
I am indeed very pleased with my result, it´s not perfect, but my best so far.

California Nebula

Taken from my camera van in the outback under -25c/-13f norwegian winter skies. This night was so cold I broke a power cable in two when unrolling it

The plan was a different project but had to go for something easier due to the chilly working conditions

Happy with the result. About 95x300s exposures through a SW Esprit 120ed and a 6200mm pro

NGC 7822

"NGC 7822 is a young star forming complex in the constellation of Cepheus. The complex encompasses the emission region designated Sharpless 171, and the young cluster of stars named Berkeley 59. The complex is believed to be some 800–1000 pc distant, with the younger components aged no more than a few million years. The complex also includes one of the hottest stars discovered within 1 kpc of the Sun, namely BD+66 1673, which is an eclipsing binary system consisting of an O5V that exhibits a surface temperature of nearly 45,000 K and a luminosity about 100,000 times that of the Sun."

It's increasingly difficult to find shots of emission nebulae that haven't been published many times already.  I've tried to do so with the attached photograph.

Taken over 10 nights in early September, I present a small section of the Sharpless 132 complex, which contains a veritable zoo of deep sky objects.  Here, I've isolated what appears to be a divine light blinding a cosmic sea horse that perhaps swam a bit too far into the deep end.

H-alpha, S2, and O3 signals are all quite strong here, and with nearly 70 hours of data, their rich interplay shows me something different every time I look at this chaotic scene.
The image comprises 66.5 hours of integration (roughly equal parts of H-alpha, S2, and O3), and was taken from my backyard in Santa Monica, CA under Bortle 7 skies.  Processing was done entirely in PixInsight, and the gear used was as follows:

M78 nebula, NGC2071 Newtonian Astrograph Version. OSC camera. Newtonian Astrograph.

About the Target:

M78 It's a reflection nebula (clouds of interstellar dust that shine due to reflected and scattered light from nearby stars) that's part of the Orion Molecular Cloud Complex, a large cloud of gas and dust around the famous M42 nebula.
Also included in this grouping are NGC 2064, NGC 2067 and NGC 2071 and other nebulae. M78 has an apparent size of 8.0 x 6.0 arc minutes. At a distance of 1,600 light-years this corresponds to a maximum spatial diameter of about 4 light-years.
