M83 o "Remolino Austral" es una galaxia espiral barrada ubicada en la constelación de Hydra a 15 millones de años luz de nosotros, relativamente cerca y bastante brillante para poder verla hasta con binoculares en cielos oscuros.
En esta galaxia se detectaron 6 supernovas en los ultimos 100 años.

Edited Hubble Space Telescope image of the spiral galaxy M101 where two Eta Carinae class hypergiant stars were discovered.
Original caption: A photogenic and favorite target for amateur astronomers, the full beauty of nearby spiral galaxy M83 is unveiled in all of its glory in this Hubble Space Telescope mosaic image. The vibrant magentas and blues reveal the galaxy is ablaze with star formation. The galaxy, also known as the Southern Pinwheel, lies 15 million light-years away in the constellation Hydra.
The Hubble photograph captures thousands of star clusters, hundreds of thousands of individual stars, and "ghosts" of dead stars called supernova remnants. The galactic panorama unveils a tapestry of the drama of stellar birth and death spread across 50,000 light-years.
The newest generations of stars are forming largely in clusters on the edges of the dark spiral dust lanes. These brilliant young stellar groupings, only a few million years old, produce huge amounts of ultraviolet light that is absorbed by surrounding diffuse gas clouds, causing them to glow in pinkish hydrogen light.
Gradually, the fierce stellar winds from the youngest, most massive stars blow away the gas, revealing bright blue star clusters and giving a "Swiss Cheese" appearance to the spiral arms. These youngest star clusters are about 1 million to 10 million years old. The populations of stars up to 100 million years or older appear yellow or orange by comparison because the young blue stars have already burned out.
Interstellar "bubbles" produced by nearly 300 supernovas from massive stars have been found in this Hubble image. By studying these supernova remnants, astronomers can better understand the nature of the stars that exploded and dispersed nuclear processed chemical elements back into the galaxy, contributing to the next generation of new stars.

This target doesnt get very high in the sky from here but I always wanted to try it so when I had a night of great seeing a few weeks back I went for it and im glad I did.
Not what I have seen from people further south but considering I thought it was decent.
8 8min subs ISO 800 stacked in DSS and then adjusted in PS CS2. Canon 500D(Gary Honis modded) , Orion Atlas mount and the scope is a Celestron 8" SCT with a .63 focal reducer(FL 1280) and a 7x40mm finderscope as a guide scope.
Data from S.S. Larsen & T. Richtler from the Danish 1.45m telescope (European Southern Observatory).
I did NOT take the data for this image myself!
Here's what I did, with the help of Jayanne English's "Cosmos vs. Canvas" workshop (see link at end):
1. Downloaded six FITS data files from the Nasa Extragalactic Database (NED) (http://nedwww.ipac.caltech.edu/), taken at six different wavelengths ranging from 3600 Angstrom to 7837 Angstrom
2. "Stretched" the FITS files using ds9, a FITS manipulator, in order to show all interesting parts of the data
3. Using Photoshop, combined the images as "screened" layers; colourized each layer according to wavelength, roughly as bluer (shorter wavelength) to redder (longer wavelength). H_alpha emission was rendered pink/magenta.
4. Blended the layers using various opacities and playing with the curves until I achieved a visually appealing result.
5. Edited out saturation lines
6. Rotated and cropped from original orientation to provide a more visually appealing image
