Got my first chance in 3 years to image Omega Centauri (NGC5139) last week with the AP180EDT at F/6.9. I used an unmodded
Canon XSi (450D) for this instead of my modded XS to gain the extra resolution and 14 bit versus 12 bit depth. The image
is made up of 12 exposures (3x30,60, 120 and 180 seconds stacked to create an HDR image).

Wow! That is amazing! I've always wanted to see it through a telescope, but can't here in Tennessee! I've been to Brazil four times, where I could have seen it, but didn't have a scope! That has to be one of the best objects in the sky! Thanks for sharing!

Nice shot of a really cool object. I have seen this one (best view through binoculars), but it sure is low.

I just wanted you to know I have this photo as my desktop background now!!!

I am new to digital astrophotography, and I have a question...

With my Fuji s3-pro - if I take a series of two minute photos and stack them, do you simply add them together to get your final exposure time? Are ten two minute exposures the same as one 20 min. exposure? That's seriously cool!

P.S. I hope you don't mind that I am using your photo on my desktop, if you do let me know and I'll take it off.
