I managed to get a better dynamic range compression with PixInsight in my old LRGB Omega Centauri image. Now I think that the stars in the core are less overwhelming, with the galactic dust cloud still visible.

Equipment: FSQ-106ED, Atik 383L+ mono, EM200, QHY5L-II guider, Baader LRGB, SharpSky focuser.

Thanks for watching!

That's a grand image, looks like some dust in the right bottom corner.

Thanks John!
Yes, there is a brown cloud of galactic dust there. The processing challenge was to show it without saturating Omega Centauri's core, using the Dynamic Range Compression feature of PixInsight.

Cheers,
Luiz

That's a great image!!!

One thing that crossed my mind when seeing this was:

How amazing the Milky Way galaxy would look to inhabitants living on a planet orbiting a star in this or any other globular cluster!!!

You wouldn't know where to point your telescope!!!

Many thanks John! At least they won't complain about light pollution, with one thousand stars per cubic parsec! :P




Thanks for the kind comment Matt, your Portuguese is quite good! :)



Thanks for the encouragement Trevor! :D

First - superb image Luiz. congratulations!

I recall reading a long time ago that from the core of omega Cen or most globular's, the sky would appear in perpetual twilight and if we lived there, we'd have no way of seeing very far in the optical. Likewise, if earth were in the centre of the mIlky way, instead of the edge we'd have little knowledge of the existence of other galaxies in visual wavelengths which in turn might retard the development of telescopes that look outside the visible spectrum - radio,UV, IR, gamma, x-ray etc. All those stars would also create a lot of noise in other wavelengths.

cheers

Viewed at 100% shows a few warts and the stars look a little oddly bright and smeared in the cluster... but Wow Luiz, when shrunk to view at 50% the cluster shines out of the page and hits you in the eye - looks great :eyepop:

Thanks Joe for the kind comments!
I was told that any planet's orbit would likely be disturbed by so many close stars, to the point that it would be ejected from the parent star system. We are fortunate indeed to live in this calm corner of the galaxy. :)



Thanks Mike for the thoughtful remarks and encouragement! :)
In fact, those problems are probably due to the short luminance exposure, only 30 minutes; the last sub was shot just before twilight.

Cheers,
Luiz
