Located in the southern constellation of Hydra, M83 is sometimes called the Southern Pinwheel. An example of a "barred spiral galaxy," the spiral arms extend from a central bar.
M83 lies 15 million light years distant beyond our Milky Way.
This image was captured under high desert skies near Santa Fe, New Mexico, USA with a telescope of 12" aperture at f/8 and an electrically-cooled CCD camera.

36 Min exposure in 10 and 3 minute frames. using my new QHY8L cámera mounted on my C8 with 6.3 focal reducer.
Next time I wil take it without the focal reducer.

This time I added the OIII (1:15 hours) and SII (50 minutes) to complete the color palette. Now the image has a more natural balance and the HII regions of the galaxy stand out of the galaxy arms. This galaxy is rich in emission nebulae and lying there would be like having the Orion nebulae all over the place.
I think I should have added more time in the luminance channel to avoid noise at such undersampling (wide field).
