Omega Centauri - NGC5139

[Jimbo_Aus]

Whilst waiting for Corona Australis to clear my roof I decided to image Omega Centauri in LRGB with 30 sec exposures. I used the new Normalized Scale Gradient script in Pixinsight, so far so good and it definitely is producing tighter stars and less gradients.

L x 90 x 30s
RGB x 60 x 30s each
ZWO183mm Pro, -15deg, Gain 53, x 75 Flats and Flat Darks
ZWO 290mm mini, OAG and 8 x 1.25" Filter Wheel
Astronomik CLS CCD 1.25" L and Deep Sky 1.25" RGB Filters
Skywatcher Esprit 100
Saxon AZ-EQ6GT mount and Berlebach Planet Tripod
PHD2 guiding, SGP Pro for acquisition, Sharpcap Pro for PA and Pixinsight for calibration and processing.

Lovely star colours :thumbsup:

Looks great Jim, like to see a hi res version.

Spot on with the shorter exposures.

Will have a look at the script.

Good effort :thumbsup:

Thanks Peter, here's a link to a higher resolution tiff image: https://drive.google.com/file/d/1AEyNZV_ipSrqHvCDs8qrNtR0ErOENjIB/view?usp=sharing

Maate, there's hi res and something that my satellite said 'file too large' or something like that, your file is 200Mbyte!!
Anyway couldn't check it out, have another go :)

[Jimbo_Aus]

Lol, try this one it's only 6.8Mb: https://drive.google.com/file/d/1csgCJH71H0ug4u8Y9Y16PBCl3MIsNLWQ/view?usp=sharing

The original link was for the uncompressed tiff file, which needs to be downloaded before being able to be opened.

Don’t think you missed any of those stars. And all a great colour.

That's better, had a look at the hires.
I would try a few things to bring out more star colours.
You should see lots of blue stars, and even a few red ones if you get it right.

Maybe less LUM to avoid pixel saturation?
Maybe up the hue saturation?
Stretch a little less?

Nice one, I saw it on the XWO face book page as well.
