M 83 Canary One telescope of the Slooh network and photoshop processing.The Southern Pinwheel Galaxy (also known as M83 or NGC 5236) is an intermediate spiral galaxy in the constellation Hydra about 15 million light-years away. It is one of the closest and brightest spiral galaxies in the sky, and can also be spotted with binoculars. Its name "Pinwheel Galaxy" is due to its spiral arms. M83 is one of the brightest galaxies in the sky; it can be found about 18° south of the bright star Spica, just north of the stars that represent the head of the Centaur and is also visible with medium-low power binoculars under discreet skies. A 150mm aperture telescope shows it as a nebula spot without a well-defined shape, in which the nucleus occupies a prominent position and dominates the halo with its brightness; With more powerful instruments, such as a 250mm, the latter appears tormented and crossed by a dark band to the south.
M83 can be observed from both terrestrial hemispheres, although observers of the southern hemisphere are strongly advantaged: the galaxy is in fact in such a position that in the very northern regions, as part of Northern Europe, it is never observable, while from the temperate belt it always remains rather low on the horizon; From the southern regions, on the other hand, the object can be shown to be quite high. The best time for its observation in the evening sky is between March and July.
Messier 83
M83 (ou NGC 5236) est une galaxie spirale de type SABc, située dans la constellation de l'Hydre Femelle.
M83 est l'un des fleurons du ciel profond austral, mais difficile à observer dans l'hémisphère nord. Pendant plusieurs années, M83 a été la galaxie la plus riche en découvertes de supernovæ.

Bien trop basse à l'horizon, elle n'est qu'a 16° au maximum au dessus de l'horizon. Les différentes couleurs sont dû à la pollution lumineuse mais également à la diffraction atmosphérique .
Tonight I was messing around with some of the datasets from the recent M83 mosaic release. Click that link if you'd like to check out the raw data. There are a wide variety of filters available, including a very nice H-alpha dataset. Very little cleaning is necessary so you can focus on making something pretty instead of dealing with boring stuff. An example of an image of the whole galaxy is here.
The goal of this image is to show the details of the nucleus without blowing anything out too badly. This is hard to do if you show the whole galaxy so I have cropped it to the central area.
H-alpha and near-infrared share the red channel equally. Green is... green. Blue represents near-UV.
The near-IR data is only half the resolution of everything else, so point sources look a little bloated. You can see some red dots scattered around and they look like color noise, but those red dots are thousands of stars visible in infrared through the thick obscuring dust lanes of the galaxy. The very center of the nucleus itself is also dust-obscured and appears as a small, yellowish orb at the exact center of the image. Using only the visible light you might guess that the nucleus is the larger, U-shaped bright area just south of the nucleus. The dust has a way of confusing things like that. If you look at only the near-IR dataset, all is clear and the nucleus is easily revealed.
A way to quickly view the individual filters is at the MAST release page. Click "Display" for any of them to bring up the very useful in-browser FITS viewer.

A galáxia Cata-vento do Sul (Messier 83) é uma galáxia espiral barrada localizada a aproximadamente quinze milhões de anos-luz de distância, na direção da constelação de Hydra. Esta galáxia possui uma magnitude aparente de +7,5.
Foi descoberta por Nicolas Louis de Lacaille em 23 de fevereiro de 1752. É a primeira galáxia descoberta fora do grupo local e a terceira descoberta entre todas as galáxias: apenas a galáxia de Andrômeda e Messier 32 foram descobertas anteriormente.
Até o momento, foram registradas seis supernovas na galáxia.
Taken with an NGT 12 telescope 12.5" f/5 and Canon 400D modified DSR. 29 x 5 mins exposures, darks, flats and bias frames. Processed in Deep Sky Stacker and CS3. Image taken from LMDSS in Heathcote on May 30, 2014.
It seems like forever since M83 released a new album. Anyhow, here's a shot of Anthony Gonzalez, who is French, from Pitchfork 2009.

M83 - Raconte-Moi Histoire
I heard about this frog,
it's a very tiny frog
but it's also very special
you can only find it in the jungle
so far away from me
but if you find it and if you touch it, your world can change forever
If you touch its skin
you can feel your body changing
and your vision also
and blue becomes red and red becomes blue
and your mommy suddenly becomes your daddy
and everything looks like a giant cupcake
Spiral galaxy M83 in Hydra photographed by Nik Szymanek using the Faulkes Telescope North, Four pane mosaic using RGB filters.
Située dans la constellation de l'hydre femelle, à la limite de la constellation du centaure, M83 est une belle galaxie mais hélas un peu basse vue de chez nous!

This clip can be found, amongst others, in the video section of my Lucid Dreams portfolio on tjblackwell.co.uk.
During my stay in New Mexico I was treated to the lightning storm display of my life. There has been a particularly active monsoon season this year, and the results are nothing short of breathtaking. The sunshine scorches the land during the daytime, evaporating huge quantities of water from both the Atlantic and Pacific oceans then driving it over the mountain ranges of South America.
Soon after midday the thunderhead clouds begin to show themselves and build up momentum until they break in the evening and illuminate the sky with electricity. Apparently some of the locals thought this was the storm of the decade, so I was privileged to photograph it! Here in the UK, we do see some nice storms but they never have the intensity or duration of the weather systems across the pond.
My camera was set up on a tripod and I was experimenting with a variety of different settings to try and capture the bolts and glowing textures inside the clouds...it seemed like the best way to display them was in a slideshow. Most of these photos are taken through a wide aperture at around ISO 800 and snapped with a finger-trigger remote shutter unit. It was the middle of the night and everything was *pitch* black - the only light you see in this sequence is coming from the clouds.
Contrary to my usual style, none of these shots have been edited at all so you're seeing the raw results straight from the camera here. I have an extra couple of minutes footage in this video clip but Flickr's policy limits the uploads to 1 minute 30 seconds. The ambient music background is a track called "Slight Night Shiver" by M83 - it seemed to match the mood of the night, when there were vehicles coasting past on Highway 180 and the sound of crickets in the distance. More lightning pictures to come soon!
M83 (NGC 5236 or the Southern Pinwheel Galaxy) is large barred spiral galaxy located approximately 15 million light-years away in Hydra. At -29 degrees declination, this object only reaches about 20 degrees in altitude from where I imaged it. I could only see the bright core when viewing through a 16” reflector while collecting data.

Imaged February 26th and March 23rd, 2014 at the Danville Conservation Area (New Florence, Missouri) with a SBIG ST-8300M on an Astro-Tech AT90EDT at f/6.7 603mm.
