Submission for APOD by David M. Norris

The Great Andromeda Galaxy (M31) is the nearest spiral galaxy to our own with diameter of about 220,000 light-years and is approximately 2.5 million light-years from Earth with an estimated one trillion stars. Andromeda is the nearest large galaxy to the Milky Way. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda.

Visible as a faint smudge on moonless nights, it is one of the farthest objects visible to the naked eye. Like the Milky Way, the Andromeda Galaxy has satellite galaxies. Two of the brightest, M32 and M110, can easily be seen in this image on either side of the core of Andromeda.

The Milky Way and Andromeda galaxies are expected to collide in around 4–5 billion years, merging to form a giant elliptical galaxy. The fate of our Solar System in such a collision is currently unknown. If the galaxies do not merge, the Solar System could be ejected from the Milky Way, or even join Andromeda!

"The Sun Illuminates the outflow from Major Hurricane Ian"

Sunset in the Panhandle of Florida in Tallahassee on September 27, 2022 brought both beauty and a scary harbinger of what was to come for fellow Floridians to our south. These upper level clouds, which traveled hundred of miles from where Hurricane Ian was located, were illuminated by the setting sun. The motion of the clouds is the outflow from powerful thunderstorms as Hurricane Ian continued its rapid intensification in the southeastern Gulf of Mexico. It would eventually make landfall in southern Florida about 18 hours after this photo was taken.

A panorama of several images at f/5.6, 1/250s, and ISO640 with Sony a7i and Sigma 35mm f/1.4 lens.

A bubble between clouds:
ImageNGC 7635: A bubble between clouds by Carlos Uriarte, en Flickr
My last image is a Bubble nebula (NGC 7635) with SHO narrowband channel and added RGB stars.
It is an emission nebula located in the constellation of Cassiopeia. The central bubble is one of three layers of hot gas surrounding the star SAO 20575, a very hot O6.5-class star. Curiously, this star (which is the one that heats the gas so that it emits light), due to its rapid movement, is not in the geometric center of the bubble. It is seen in the lower left area of the center of the bubble. It is a very young star (about 4 million years old...) and is expected to explode as a supernova in about 15 million years (more or less a million...). Interestingly, this nebula is located in a region where another supernova has already exploded.
It's great a lot of signal of SII, and aprecciate a large structures between bubble.

Imagengc3621 by Mathieu Guinot, sur Flickr

NGC 3621 is a beautiful spiral galaxy located about 22 millions light-years away in the constellation of Hydra. Its morphological classification is SA(s)d, which indicates this is an ordinary spiral with loosely wound arms.

Like other spirals, it has a flat disc permeated by dark lanes of material and with prominent spiral arms where young stars are forming in clusters (the blue dots seen in the image). But while most spiral galaxies have a central bulge — a large group of old stars packed in a compact, spheroidal region — NGC 3621 doesn’t.NGC 3621 is also interesting as it is believed to have an active supermassive black hole at its centre that is engulfing matter and producing radiation. This is somewhat unusual because most of these so-called active galactic nuclei exist in galaxies with prominent bulges. In this particular case, the supermassive black hole is thought to have a relatively small mass, of around 20 000 times that of the Sun.Another interesting feature is that there are also thought to be two smaller black holes, with masses of a few thousand times that of the Sun, near the nucleus of the galaxy. Therefore, NGC 3621 is an extremely interesting object which, despite not having a central bulge, has a system of three black holes in its central region.

IC 5332, also known as PGC 71775, is an intermediate spiral galaxy about 30 million light-years away in the constellation Sculptor. This delicate spiral galaxy is viewed from Earth nearly face on and is beautifully symmetrical, and unusually faint with a very low surface brightness. It has a very small central bulge and open spiral arms accounting for its classification (SABc).

Red Gradient Moon
Photo description:
After stacking the moon, which was taken continuously at 8-second intervals, the change in the color of the moon can be clearly seen. When the waxing crescent moon sets, the bright yellow moon surface gets closer to red. This is a phenomenon caused by atmospheric scattering.
Equipment Details:
Canon EOS 600D + SIGMA 60-600mm F4.5-6.3 S DG OS HSM Sports
Post-processing Details:
The moon is stacked together with the software Sequator156, which is shot continuously at 8-second intervals.

Orion Nebula and The Horsehead Nebula, wide field (5h38' version)

This region, like possibly many of you, is the reason why I started photographing the night sky.
One and a half years ago I took my first poor, noisy and undefined picture of this region, that was my
first astrophotography. Since then I never took the time and had the courage to try it again due to the fear of
a new frustration. Today I am proud of my result and so I share it with you.

Nebulae are clouds of dust and gas that represent either end or the beginning of a star’s life cycle.
Some are places where stars have died, others where stars are forming. The Orion Nebula is the latter.

At only 1,344 light-years away, in Orion (the Hunter) constelation, the Orion Nebula is the closest and one of the brightest nebulae
visible from Earth. This means it can be seen with the naked eye up to mid-March when viewed under
dark skies.

The Horsehead nebula is a dark nebula composed of interstellar dust that blocks starlight
as well as the ionized gasses which comprise IC434
(the bright red emission nebula that is the backdrop of the Horsehead Nebula).
The Flame Nebula on the left is a reflection nebula that is lit
by nearby Alnitak (one of Orion's three belt stars).

NGC 2903 in H-alpha and continuum light (final version)

NGC 2903 is a barred spiral galaxy in constellation Leo.

The image is calculated with and without H-alpha information. By toggling between the two variants the correlation between HII gas clouds and bluish regions (containing young stars and also OIII gas) can be visualized.

M94 in H-alpha and continuum light (final version)

M94 is a spiral galaxy in constellation Canes Venatici with two ring structures. The inner ring is an active star formation region and contains a lot of young blue stars and HII regions, the broader outer ring is very faint.

The image is calculated with and without H-alpha information. By toggling between the two variants the correlation between HII gas clouds and bluish regions (containing young stars and probably also OIII gas) can be visualized.

ImageNGC247 LRGBHa by Mathieu Guinot, sur Flickr

NGC 247 (Caldwell 62, or the Claw Galaxy) is an intermediate spiral galaxy (although it is sometimes classified as a dwarf spiral galaxy) about 11.1 millions light-years away in the constellation Cetus.
NGC 247 has an unusually large void on one side of its spiral disk which contains some older, redder stars but no younger, bluer stars.

NGC 247 is one of several galaxies that is gravitationally bound to the Sculptor Galaxy (NGC 253). These galaxies form a small core in the center of the Sculptor group, which is one of the nearest groups of glaxies to the Milky Way. Most other galaxies associated with the Sculptor Group are only weakly gravitationally bound to this core.

NGC 7793 is a flocculent spiral galaxy located at a distance of 12.2 million light-years in the southern constellation of Sculptor. It is one of the five brightest galaxies within the Sculptor Group.
The morphological class of NGC 7793 is SA(s)d, indicating it is an unbarred spiral (SA) with no inner ring structure (s) and that the arms are loosely wound and disorganized (d). It is flocculent in appearance with a very small bulge and a star cluster at the nucleus. There are two nearby dwarf galaxy companions.

The beautiful NGC 4945 (also known as Caldwell 83) is a barred spiral galaxy located about 13 millions light-years away in the constellation Centaurus. It is almost the size of our own Milky Way galaxy, and it is one of the brightest galaxies of the Centaurus A/M83 group, a large and nearby group of galaxies.
