Omega Centauri

Here is one more image, if I may. My goal in this image was to capture the halo of faint stars surrounding the main body of the cluster.

There are a lot of stars there!

Damn fine shot, Tom. Plus a few galaxies thrown in, too boot!!!!.

10 Million stars in the cluster, give or take a few

Another grand image Tom.
See the bonus galaxies in there as well.
Great work.....cheers Kev.

Hi Tom,

I like it but it seems a tad too blue to me. You certainly got all the stars, resolved to the core etc. I know it has a blue look to it but perhaps not that much.

I hope you make an excellent recovery from your surgery.

Greg.

Dam Tom what ya been doing storing all these pics away for a rainy day then popping them all out one after another
nice work cheers

Wow Tom, the star field is absolutely amazing and testament to what must be some outstanding equipment and well honed techniques.

I especially like the enhanced star colours and 3 dimensional impact from the variety of star sizes. And the galaxies ....

Certainly is a lot of stars in the outer area. I love the spread of colour in your stars. Beautifully processed and such fine pin point stars.

Thanks Greg. I too thought that it was a tad too blue but when I looked again at my G2V data and histogram it looked correct. So, for better or worse, I just left it. Maybe I'll tone it down some though.

Sorry to hear about your AP adapter. Yes, FlI has a pretty shallow thread.

Colour is often the hard part of the image so it could simply be my preference. It definitely has a lot of blue stars in it for sure.

How do you do your G2V callibration?

Greg.

I follow Don's method. It's simple.

Thanks Tom,

I feel like I am getting tuition from a master craftsman!

Cheers,

Greg.

Congrats on a beautiful image, and congrats on APOD today!

Well done!

You have some stunning APOD's Tom, well done

gregbradley · #18 02-03-2009, 01:10 PM

That looks good Tom.

Did you also bring out that dust in the bottom right side?
I notice it shows when the mouse cursor is on the page and disappears when the cursor
is off the page. Is that intentional or an artifact?
I can't believe you found dust in Omega Centauri

How do you get the dust to show up so well? Careful curves for that
part of the curve where the dust is (down low)?

Greg.

Hi Greg,

The dust is real but very very faint. I brought it out with curves but only made it stand out with the mouse-over. I am surprised that dust was in the region as well. Maybe it is flux nebulosity. I'll have to check.

Hi Tom, Stunning image.
Is that green dot at the six o-clock position an artifact?
