"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).

An image like this is just so stunning to me - the amount of stars visible is just staggering. I wonder what the night sky would be like in the middle of a star cluster.

The Heart and Soul Nebulae, a 12 pane HD mosaic

by Aleix_Roig
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.

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. ⠀

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).

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.

The Soap and Crescent Nebulae - WOLF-RAYET star

Posted: 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,

M94 in H-alpha and continuum light

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.
