Antares in Scorpius - Mk II

Antares is a giant or supergiant star. Giant stars are large and bright and appear in the brighter portion of the Hertzsprung-Russell (H-R) diagram. Red giants, appearing on the lower-temperature side of the "giant" region of the H-R diagram are stars that no longer burn hydrogen in their core, but can burn hydrogen in an outer shell surrounding a now helium core. They are the next step in the life of a main sequence star like our sun. When a main sequence star has fused a certain portion of the hydrogen in its core, the star begins to swell, increasing in size by a factor of 100. As the star expands, it also cools, and becomes redder, hence the name "red giant". Most red giants will end their lives as white dwarfs after they shed their outer shell as a planetary nebula.

Antares is both a variable star and one member of a multiple star system. It is possible that this star is an "eclipsing variable". Eclipsing variables are members of a double star system which pass directly in front of their companion stars during their orbit. When this happens, light from the companion star is blocked, and the binary star appears fainter to observers on Earth.

To the left of Antares is the Cat's Eye (M4). M4 is a globular cluster, 10 billion years old. Only 7200 light years away, M4 may be the closest globular cluster to our solar system. Because Antares is a red supergiant, and only 1.5 degrees west of M4, it makes it tough to see M4 with the naked eye. Binoculars reveal M4 as a very bright and round globular. The cluster's core is loosely concentrated with a string of 10th magnitude and fainter stars running across the centre, partially obscured by clouds of interstellar matter. A remarkable object in a telescope.

This composite consists of one set of images; one set of 20 images taken at ISO-1600.
Each individual image was a 45 second exposure.
IRIS was used to calibrate each image (dark subtraction [median combined master dark] and flat field division [median combined master flat {lights, darks and offsets}]), to register, align, and finally stack.
Photoshop CS2 was used to adjust levels, curves, brightness and contrast, colour balance, frame and resize the final composite.

Daily Deviation

Given 2006-06-24
Antares in Scorpius - Mk II by *octane2is a beautiful and technical achievement. I've never seen anyone on dA capture the stars this beautifully. As far as I am concerned, the best of Astrophotography. ( Suggested by Beachrockz4eva and Featured by hesitation )

This is simply gorgeous. "The heart" is my second favorite star, but for some reason tau Scorpii, one of "the arteries" of the heart is my favorite. Look up the constellation of scrorpius on Google earth. For some reason, tau scorpii just stands out to me. I love this phot, nice work.

This is an amazing photograph.

WoW what an awesome image. Did you use any sort of magnification if so how much? I'm really amazed at the amount of nebulosity that is captured in this image.

Great pic.

Demonhawk14,

Thank you for the compliment.

No magnification was used. It was taken through a 50mm prime lens.

What you're seeing isn't actually nebulosity, but the glow of stars from towards the centre of our Milky Way Galaxy.

I will attempt this region again this year, using a modified camera which will actually pick up the beautiful blue reflective, and red emission nebulosity.

H

popp-photo,

Your compliment is far too kind.

Astrophotography is a difficult pursuit -- you often feel like a lonely mountain climber -- there is a lot of work involved, but, I think the end result is more than worth the effort.

Thank you.
