Description

This constellation in located Southeast of the Center of the Galaxy (EQ Coordinates). It is truly beautiful from a Dark Sky, and, as it is realively faint, it is only visible from darker skies (~Bortle 5 or less, I imagine). In binoculars it is truly amazing, and in long exposure photographs, such as this one, the "Corona Australis Molecular Cloud" is detectable. This molecular Cloud would be clearer in longer exposures (>1h), but in this 0.4h image it is apparent as the Dark Nebulosity around the stars γ CrA and ε CrA.

Corona Australist is, however, only visible to latitudes below 35-40º North, being very low at the horizon for such latitudes. As this image was taken from 22º S, this constellation shines brightly in the Zenith at the Winter (for the Southern Hem.).

This image is the last one of my work in this year's July (2014). I was quite happy with all of my pictures, and I've learned many things, from the Polar Alignment, to the Post-Processing. Thanks for your help, and now, with the HEQ5, I hope I get even better pictures. Taken from Rural Skies (Bortle 3-4), in MG, Brazil. Thanks for seeing.
