Thank you very much, Will. Your Omega Centauri image is spectacular, and Jason's Orion Belt and Sword is a beautiful image as well. So, congratulations to both of you for posting such exceptional astrophotos.

Great work Scott - well deserved win.
You are showing the power of stacking so many images:
The square root of 329 is 18.
That's 1/18th the noise & it shows.

cheers
Allan
