The Andromeda Galaxy - M31
09.07.21 - 04:00 am.
This is one of my favorite DSO. It has inspired me all the way since I started into astrophotography. The jaw dropping andromeda galaxy is 2.5 million light years away from us, and shows a beautiful spiral shape that has 200,000 light years in diameter!
This is a very low target from my location in Perú (-12° latitud). I had to wait a whole year to get it.

It only took me 38 minutes, thanks to the fast RASA 8 optics.

All shots were done in one night, near Santiago de Tuna town, up in the mountains, 3 hours away from Lima city in Perú.
Skies there are bortle 3, very beautiful and clear! It is located 3000 meters over sea level!

Hope you all like it.

The Eta Carinae nebula, classified as NGC 3372, covers three degrees in the sky, which at a distance of 8800 light years corresponds to a diameter of 460 light years. Two other nebulae have been added to it, but they are probably neighboring nebulae to Eta Carinae and not directly connected. The distances to them is not very certain but they are probably also the arm of Sagittarius.

ImageARP 147 - Hubble scores a perfect 10! by William Ostling, on Flickr

To get this awesome image, Hubble aimed its prime working camera, the Wide Field Planetary Camera 2 (WFPC2), at a particularly intriguing target, a pair of gravitationally interacting galaxies called Arp 147.

The two galaxies happen to be oriented so that they appear to mark the number 10. The left-most galaxy, or the "one" in this image, is relatively undisturbed, apart from a smooth ring of starlight. It appears nearly edge-on to our line of sight. The right-most galaxy, the "zero" of the pair, exhibits a clumpy, blue ring of intense star formation.

Data was used from the following proposals: https://archive.stsci.edu/proposal_sear ... t&id=11902

R: 814w
G: 555w
B: 450w

Imagerho-ophiuchi-cloud-complex by Joe Schlaf, on Flickr

More commonly photographed in it's entirety or in combination with Milky Way and it's galactic core, this is a deeper dive into the Rho Ophiuchi cloud complex. Seen here are the blue reflection nebulae of IC 4603, IC 4604, and IC 4605. The cool blues are offset by the mingling of dust reflecting the brilliant orange light of Antares (out of frame to the left).

Messier 8 and Messier 20 objects, also known as the Lagoon and Trifid nebulae (left and right in the picture respectively) are located in constellation Sagittarius. Both are estimated to be between 4,000 - 6,000 light-years away from us and are classified as emission nebulae. Inside them takes place an active star formation feeded by those huge HII clouds.

IC 5067 object, also known as Pelican nebula, is located in constellation Cygnus. Is part of the same H-alpha emission region of the famous North-America nebula. Dark nodules or rather "Bok globules" can be easily observed. They are formed by molecular hydrogen and dust, being usually star formation areas. These Bok globules are just the ones that define the "eye" and the inner structure of the "beak" of this giant Pelican which spans 30 light-years and "flies" 1,800 light-years away from us.

Arp-Madore 2026-424

ImageArp-Madore 2026-424 by William Ostling, on Flickr

Data was taken by Hubble's Advanced Camera for Surveys (ACS)

In this Hubble Space Telescope image, an uncanny pair of glowing eyes glares menacingly in our direction. The piercing "eyes" are the most prominent feature of what resembles the face of an otherworldly creature.

But this is no ghostly apparition. Hubble is looking at a titanic head-on collision between two galaxies.

Each "eye" is the bright core of a galaxy, one of which slammed into another. The outline of the face is a ring of young blue stars. Other clumps of new stars form a nose and mouth. The entire system is catalogued as Arp-Madore 2026-424.

Data was used from the following proposals:

"Fire Moon"
https://www.rddnjk.com/
Copyright: Russell King. On the evening of July 20, 2021, I looked up and saw what appeared to be the Moon in Eclipse. I was use to see the Moon like this when rising, but it was very high in the sky and also was phased. I realized that the California Fires were creating the Eclipsed effect and being only 3 miles from the Ocean, the smoke was creating this beautiful Moon. It was very hard to focus properly because of the polluted atmosphere, but I did my best. Oh, did I mention that I was only 3 miles from the "Atlantic Ocean". Neptune, N.J.. 2000 miles away

NGC 4535 - The Lost Galaxy


ImageNGC 4535 - The Lost Galaxy by William Ostling, on Flickr

Data was taken by Hubble's Wide Field Camera 3 (WFC3)

Located in the constellation of Virgo (The Virgin), around 50 million light-years from Earth, NGC 4535 is truly a stunning sight to behold. Despite the incredible quality of this image, taken from the NASA/ESA Hubble Space Telescope, NGC 4535 has a hazy, somewhat ghostly, appearance when viewed from a smaller telescope. This led amateur astronomer Leland S. Copeland to nickname NGC 4535 the “Lost Galaxy” in the 1950s.

The bright colours in this image aren’t just beautiful to look at, as they actually tell us about the population of stars within this barred spiral galaxy. The bright blue-ish colours, seen nestled amongst NGC 4535’s long, spiral arms, indicate the presence of a greater number of younger and hotter stars. In contrast, the yellower tones of this galaxy’s bulge suggest that this central area is home to stars which are older and cooler.

This galaxy was studied as part of the PHANGS survey, which aims to clarify many of the links between cold gas clouds, star formation, and the overall shape and other properties of galaxies. On 11 January 2021 the first release of the PHANGS-HST Collection was made publicly available.

Data was used from the following proposals:

G: 555w
B: 438w + 336w + 275w

Jewels in a Red Sea. KG Observatory, Julian CA.

Star Cluster IC1311 is located approximately 4,000 light years from Earth. The cluster is embedded in a giant emission nebula. The nebula is glowing from the ultraviolet light from hot, massive blue stars in the nebula.

STORY:
Star Trail over Salto Santa Maria, one of the main waterfalls of the Iguaçu Falls complex in Brazil.
Photographing Iguazu Falls at night has always been one of my priority projects. For that, it was necessary to obtain a special authorization from the environmental agency responsible for national parks in Brazil. Finally, in early 2021, I got this authorization and set out to put my plan into practice.
I spent 4 days inside the Iguaçu National Park with exclusive access at night to the Falls for me and my students. The first challenge is to walk around the park at night knowing that several jaguars reside there, which are frequently seen by employees and tourists. In the area closest to the main waterfalls, the big challenge is to make long exposure images with the strong water spray from the more than 1.5 million liters per second that fall through the waterfalls. Working with exposure times longer than 30 seconds became an almost impossible task and the lens was never dry.
To assemble the Star Trail, the Sequator software was used.

NGC 2903 in H-alpha and continuum light

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 probably also OIII gas) can be visualized.

Full "Buck" Moon of July, with Clouds
ImageFull Buck Moon with Clouds by Tom Glenn, on Flickr
The Full "Buck" Moon of July appears in this single exposure photograph, shining through cloud cover in San Diego, CA, as observed in the early morning hours of Saturday, July 24, 2021, at 02:29 PDT.

Full sized image:
https://live.staticflickr.com/65535/513 ... 310f_o.jpg

I wasn't originally planning any photography on this night, but I looked out the window and noticed an amazing collection of clouds covering the Full Moon, so I raced outside to quickly capture this photograph. Normally, the full Moon is so bright that one cannot simultaneously expose for the Moon and foreground elements at night. However, in this case the clouds reduced the brightness of the Moon just enough to allow a single exposure to capture the Moon, as well as the clouds that it was illuminating. The resulting colors are no doubt an interesting mix of moonlight, a thick atmosphere (low elevation), and light pollution. Image captured in one exposure of 1/25s taken with a Nikon D5600 and 70-200mm lens at 200mm, f/2.8, ISO 100.
