cafuego 🔭🤦🏼‍♂️

I can finally post a shiny new bling! Late last year a bunch of members of the Astronomical Society of Victoria formed the Southern Supercluster imaging collaboration.

The idea was to all image the same target and get at least 10 hours of image data with each of our various telescopes and cameras, then combine all that data to bring out faint details that are hard to accomplish if all you have is the photons you catch by yourself.

The first target, our practice target, was a patch of the Large Magellanic Cloud near the Tarantula nebula and the "Cosmic Reef". Together we collected over 260 hours of data, which was all combined by the group coordinator, Eddie Pang.

He then sent stacked and normalised FITS files to all of us, to process to our hearts content.

This is my first proper attempt, combining the hydrogen and oxygen data into a HHO colour image. I chose that because I am red/green colour blind and with the usual palette I am completely unable to see the faint red hydrogen wisps that stand out clear as day in yellow now 🤩

I've included a small-ish version of the entire field of view, as well as three crops of specific areas of interest. You can see the full riotous 7700x5900 pixel catastrophy at flickr.com/photos/cafuego/5439

SSC group members: E.Pang, R.Wiltshire, P.Lieverdink, A.Campbell, O.White, M.Tymms, B.Jurkowicz, A.Latta, S. de Lisle, J.Wilson, P.Milvain, J.Morley, K.Chandrashekar, R.Carroll, S.Markus, T.Graziani, S.Wilkins, A.Haskian, J.Bordignon, C.Hill, A.Paulin, S.Nikolaou, and G.Dite.

Because this is a collaboration and not all my own work, these images are all rights reserved and not creative commons.

Very deep view of the Large Magellanic Cloud showing dozens of bright nebulae in yellow/orange as well as s few blue ones. Each of these nebula has a star cluster embedded in it. The entire scene is criss-crossed by faint wisps of hydrogen. A very large and bright nebula (the Tarantula) sits at top right. At bottom right an elongated bright patch marks the location of part of the central bar of the MC galaxy. The entire scene is full of tens of thousands of stars.
The "Cosmic Reef" section of the main image. A collection of colourful nebulae sit between an absolutely enormous open star cluster and a darker area that consists of faint wisps of gas. Fine detailed arcs of gas and dust are visible in each nebula, as well as bright stars near their cores that light them all up.
The "Henize 70" section of the main image. A nearly spherical yellow nebula on the right hand side marks where a star cluster is blowing a so called "super bubble" in the surrounding hydrogen gas. This super bubble is about 400 light years in diameter and faint filamentary ripples are visible on its surface. On the left hand side, two wispy, fainter more blue-ish nebula mark where stars have already exploded and left the distinct mark of oxygen.
The "Tarantula Nebula" section of the main image. This ridiculously large and bright nebula is visible from Earth with the naked eye despite being 150,000 light years away. Its over-exposed core looks a little bit like a squashed spider. It is surrounded on all sides by loops of hydrogen gas and embedded in those loops are countless "smaller" nebulae which are each probably still larger and brighter than the orion nebula and are all producing new stars at an incredible rate. At top right. a dense mass of stars marks part of the LMCs central bar. Embedded in that are yet more "small" yellow nebulae.

boost encouraged :boost_ok:

i don't know how many Tops, Masters, Mistresses, Dom/mes, etc follow me but question for those who do

what are your thoughts on brats?

i personally don't mind they exist, but none of mine would dare. i'm the type to give book reports on non-fiction for bratty behavior

Neighbouring #Somaliland has been deeply destabilized by a recent civil war that allowed for the secession of #SSC-#Khatumo last summer, as well as the signing of a MoU with #Ethiopia that opens the possibility of an all-out war with her Somali neighbour, including insurgencies in Somaliland itself and in the Somali region of Ethiopia. Somaliland's leadership is itself fragilized, hindering the state's capabilities in terms of maritime security.
