M94 in H-alpha and continuum light

by stefanz » Fri Jul 30, 2021 1:21 pm

M94 in H-alpha and continuum light

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.

The Soap and Crescent Nebulae - WOLF-RAYET star

by Aleix_Roig » Fri Jul 30, 2021 12:02 pm

I would like to share with you my recent work on this field.

http://astrocat.info/the-soap-and-crescent-nebulae/


The Soap Nebula, PN G75.5+1.7, was discovered by the amateur astronomer Dave Jurasevich back in 2008. This faint nebula can be detected using narrow band filters with long integration times. We can find it near the popular Crescent Nebula, NGC6888.

Both nebulae are surrounded by huge clouds of gas and dust in the constellation of Cygnus. NGC 6888’s central star is classified as a Wolf-Rayet star (WR 136). This star will become a supernovae in the near future.

NGC 6888 is located some 5,000 light-years away from Earth.

To capture this image I used Hα and [OIII] narrow band filters in order to capture the faint details of this amazing deep sky structure.

Thanks for your attention,

The Lost Farm

For June Milky Way shot, we went in one of the most dark and amazing location "near" home. It's Masseria Cippano, Otranto, Salento, Lecce -> ITALY.
What you see is an old building that in medieval time was used to defend our country from Saracens invasions, our enemies. It was the key of defense system of the Holy Roman Empire, strongly wanted by king Carlo V. After the end of the war, the building was transformed in a big farm.
In this place was recorded the first images of "Mine Vaganti" movie from Ferzan Ozpetek, with 13 candidates to David di Donatello 2013 Awards.
Here you can taste an impressive silence that will bring you to really live that days of war and work in the past centuries.

Next Big Adventure
www.mattdieterich.com
Copyright: Matt Dieterich In 2015, I took a leap of faith and went on an adventure to fulfill my dreams of working in a National Park where I could share the night skies with visitors. That experience of working as an Astronomy Ranger at Mount Rainier National Park had such a profound impact on my outlook of what the night sky means to us as humans. The time on the mountain helped me reflect on how I want to leave my mark on society, which is to help inspire others to connect with the night sky and outdoors. Last week, the time was right to start an even greater adventure with the woman I love and who has supported me over the years as a travel astrophotographer. I wanted to capture our proposal under the stars at Mount Rainier to kick off this next big adventure. Fortunately, we had clear skies and walked away with this image and a big YES to the proposal! (5 image panorama with a Spencers' modified Sony A7siii, 24mm lens at f/1.4, ISO6400, and using 10 second images).

ISS and Llangorse Lake by Mathew Browne via PhotoHound

I love it when a plan comes together! ⠀

Llangorse Lake in the Brecon Beacons provided a perfect, serene place and time to capture the International Space Station passing overhead.⠀

This was probably the highlight of an evening shooting with Dwayne Jones Photography - he's technically in this shot I think, photographing the ISS in those reeds to the right⠀

It's a wonderful location for photographers - lots of bird life, loads of compositions and dark skies for astrophotography when skies are clear. ⠀

The Heart and Soul Nebulae, a 12 pane HD mosaic

by Aleix_Roig » Mon Jul 26, 2021 12:15 pm

In the Perseus arm of our galaxy we find two spectacular nebulae, the Heart (IC 1805) and Soul (IC1848) nebulae. Located around 7,500 light years away from us both cover a wide region of the night sky, in the Cassiopeia constellation. Several full moons could fit inside this image. Both nebulae have high emission on the red spectrum and especially in the H alpha line. With the use of this filter we can capture its structure. This is image is the result of combining a 12 pane H alpha mosaic and a 8 pane RGB mosaic captured in 2017 and finally processed this July 2021.

"Rho Ophiuchi cloud complex"

Rho Ophiuchi cloud complex is a close and active star forming region located in the constellation of Ophiuchus. It is mainly composed of gas and dust and hosts several amazing colorful nebulae. This region is located some 460 light-years away from Earth. It's been a very difficult target due to its low altitude on the south horizon from my home observatory (at a latitude of 40º north).

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.

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 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:
https://archive.stsci.edu/hlsp/phangs-hst

R: 814w
G: 555w
B: 438w + 336w + 275w

"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
