Canon EOS 1000D
20x15 second exposures
1600 ISO
10 inch (25cm) F/4 Newtonian Reflector Telescope
NEQ6 Pro Goto Mount (unguided)
Baader Coma Corrector
When I first purchased my telescope setup, I was challenged to get a shot of this Southern Hemisphere delight by Insomnia Works [link] one of the great astrophotographers I have found here on DA. Please check out his amazing photos.
Once I get my guideing setup working properly, I'll be sure to revisit this object to produce a more detailed picture.

Globular clusters are some interesting targets for a starting astrophotograper. Omega Centauri is certainly among the best star clusters to capture in picture, as it is exceptionally wide and bright.
The shots combination at 1600 ISO is crisp, even without auto-guiding. The use of such high ISO is crucial for such picture. It is needless to say the NEQ6 mount shows great sturdiness.
Although a coma corrector as been used, there is still some coma on the upper left side of the picture, but I believe it may be due to the mirror itself.
I believe it is so far Greg best astrophotography shot. I can't wait to see this guiding system working and for Greg to unravel us the Southern skies!

Hopefully I can continue to learn and capture some more deep sky delights for you.

I have shown your picture to a work colleague in the little astronomy shop I work. He loved your picture too, and God knows how many he have seen! He also shares my opinion.
I can't wait for another of your deep sky pictures!

That almost looks like glitter exploding in the sky.
That's awesome.

Cool. Found the thing just three weeks ago after MANY years attempting to see it (observing from a latitude of 40ΒΊN), and while of course it was impossible to resolve it, resembling M13 seen with binoculars, was really worth of the effort.

hi greg,
to get longer exposures on your camera you can use on of the smaller headphone jacks with the buttons. set your exposure to bulb and hold it down for the required amount of time

Hello. The reason I did short exposures for this photo, is because I did not have my autoguider up and running properly at the time. There is only so much a properly alligned mount can do. Really long exposures on even perfectly alligned mounts will suffer from tracking errors. Thanks for letting me know about bulb mode, but I am already well aware of it and I have two different shutter releases for the stereo jack. One is just a normal shutter release. The other, I can dial in the number of shots, how long each exposure is, how long the delay is before the first exposure and how long the interval between the exposures is. Keep up the good work with your astrophotography. I'll be watching for what else you can produce with your telescope and that EQ5 Mount.

OMG
This picture can go straight to any album or book of astronomy.
