First time APOD submitter. This image was the result of a few nights' worth of clear weather. Originally I had included SII data, but I found that I much preferred the image using only the Ha and OIII data combined in the HOO palette.

In the shot, the two Full Moons were taken at different times, but using the same technique with a Canon 6D and binoculars with a 900mm focus lens. The Full Moon in January was almost 100%, but still not, because if it really is that much, then we are talking about a lunar eclipse. In the case of September, the illumination was only 99.7%, but again it was more than enough for the disk to be slightly damaged.
The goal was to photograph the Perigee and the Apogee Full Moon with the same equipment and the same settings. The juxtaposition of the two lunar disks shows absolutely spectacularly the approx. 50 thousand km difference.
With the naked eye, we do not perceive that the size of the Full Moon changes, but the Perigeee Fullmoon near the Earth is 15% larger and 33% brighter than the one far from the Earth.

Hello

Following my 3 days of good weather, when the lace of the Swan sets, I could not help but try to image the nebula of the horse and orion, the constellation of Orion rises it is around 2:30 am, on the nights I managed to collect 90 photos but as it is still too low on the horizon, I was able to keep that 36 photos of good quality we will say!

The Lion Nebula Sh2-132 - a deep view
I'm not sure why but I have been obsessed by this nebula for a while, as it is so faint, understanding more about its true structure and morphology is interesting.
I posted a picture of this subject a couple of weeks ago, but I was able to image consistently for another three nights to particularly get more SII and Ha data.
The "Lion shape is still there, but now less distinct and one can see more of how this object is composed.
The area alongside what represents the lion's tail is now distinct with the dark nebulae and faint wisps of SII emission can now be seen encircling the powerful OIII region ( shown in Blue) something I have not seen before.
Also as a bonus there are two Planetary nebulae in this image.
To the lower right there is a tiny blue smear which is Abel 79, and much larger PN to the top/ right which despite searching I cannot identify.
The Lion Nebula lies about 10,000 light years away and appears on the sky on the border of the constellations Cepheus and Lacerta.

M20, the Triffid, the nebula that everyone has seen a picture of even if they aren't interested in astronomy. For some reason I'd never seen an image of the Triffid that showed a lot of detail, especially in the reflection nebula so I was surprised and a bit amazed when I saw the data we had. All the wispy detail just jumped off the screen.

This uses all seven filters (L, H, O, S, R, G, B). The L and narrowband filters were combined to make a new luminance. This kept the reflection components visible in the L but also the narrowband details that were only barely visible in the L. I weighted the combination L + 0.75H + 0.5S + 0.5O and then rescaled there result. This did a good job of giving me the best of both narrowband and broadband details.

Good evening everyone,

The long nights arrive, the good weather continues, and the acquisition of a new lens make it time to resume astrophotography!

From the French Basque coast, on the seafront, with a lighthouse in front, a lot of light pollution, and a moon very present, I wanted to make the lace of the Swan with a dual band filter Ha-Oiii Idas NBZ.

With the collaboration of Philippe Bernhard for the treatment!

Touching Rho Ophiuchi.
Copyright: Marcelo Maturana Rodríguez (@matuutex)
Location: Vicente Pérez Rosales National Park, Lakes Region, Chile
Date: 03 July 2023

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, which in detail is the cloud formation of Rho Ophiuchi.

The trailer, the Magellanic clouds, the milky way and the AIRGLOW phenomenon

Here in this image of a rare moment, with temperatures reaching 0ºC, I came across this unique moment, a scene that will remain with me for the rest of my life.

Here we have, on the land part, me and a dirt road.

In the sky, this greenish effect called AIRGLOW (an effect of chemiluminescence, where the energy of the daytime sun, causes divisions in the queues containing oxygen, which recombine at night, giving this appearance). Furthermore, in the region above my head, we see the Large Magellanic Cloud galaxy) and further up the arm of our Milky Way galaxy.

The Heart Nebula and SNR G132.7+01.3

Taken on August 26, 2023,this is a 4+ hours of star trails. This particular image was done in "Comet Mode" to show tails on the stars so the total rotation here is only a small portion of it but it clearly shows that the earth is rotating with Polaris near the center. A full star trails image shows that Polaris is in fact, not at the celestial north pole (that image is also available).

SH2-129 / OU4

In the constellation of Cepheus, OU4, known as the Giant Squid Nebula, is a planetary nebula recently discovered because it is very faint. It was Nicolas Outters who revealed it in June 2011. It is located at approximately 2300 light-years away and measures nearly 1 degree, which is twice the size of the full moon. It can be observed through the emission nebula SH2-129, known as the Flying Bat Nebula. The latter is situated at a distance of 1300 light-years with a size of 2 degrees and 20 minutes.

Image made with Askar 400 and reduce x0.7 (280mm). Asi 1600mm pro in HOO with 28h acquisition time.

Last night's absolutely spectacular display of the aurora borealis was visible throughout the mainland UK where skies were clear. It was the result of a G2 geomagnetic storm.

This photo was taken just before midnight at Paxton's Tower, Carmarthenshire, Wales.

This is my favourite local photo haunt, and honestly I must have been here over a hundred times to photograph the night sky but nothing has ever come close to this. For over an hour the horizon beyond the clouds glowed with greens and pinks but for a few minutes the sky burst into life with impressive pink pillars that were visible to the naked eye.

It's very rare to get such a strong display this far south!

Nishimura comet from Faenza, Italy

The alarm rings. 4:00 am. You get up, drive to the place, and set everything up.
The comet is barely visible with a pair of binoculars. Almost impossible to see with naked (and sleepy) eyes through the city haze.
The camera sensor picks something up! But time ticks fast, and you have only 20 minutes before the Sun washes everything up with his calm dawn. At home, you stack the photos, subtract the diffuse light, and wow: you discover that the visible comet tail is much longer than you ever expected! It is barely contained in the frame. Bye comet Nishimura, your visit was quick but you definitely left the mark, on me at least.

Photo taken by me on 9 September 2023 around 5:40 am GMT+2 from the hills of Faenza (RA), Italy. The small tower on the right in the foreground is the iconic tower of Oriolo dei Fichi, built in the 15th century.
I am Paolo Girotti, an Italian post-doc in particle physics, 28 years old. My instagram account is @astrogyres .

The photo is a composite of:
38x30" f5.3 70mm iso1600 for the sky and comet (tracked)
70" + 10" f7.1 70mm iso800 for an HDR of the foreground
All shots taken from the exact same spot with a Nikon D3300 + Nikkor 18-105 @70 mm. The foreground shot was taken 30 minutes before the comet shots (so that city lights were still on).
