Omega Centuri

[smader (Stacy)]

Here is a total of 4min combined 3200 + 6400 ISO image of Omega Centuri, Canon 1100D at prime focus. Using PS CS2 for processing, I found it hard to remove the green tinge from the outer stars. I'm not sure if using the 6400 ISO images are introducing this, so I'll look into reprocessing just using the 3200 ISO images.

Cheers!

That's good, Stacy

Thanks Laurie,

I'm still finding out what is the optimum setting for this camera. Using ISO 800 seems the best compromise between exposure and noise.
