NGC 5139: Globular Cluster Omega Centauri - The King of The Skies

Located in Centauri constellation and distante 15,800 light years from Earth, Omega Centauri is the most massive globular cluster known with 4 million Solar masses.

It has been speculated that Omega Centauri is a Dwarf galaxy that was absorbed by our Milk Way. Indeed, Kapteyn's star, which is currently only 13 light years away, is thought to originate from Omega Centauri. Omega Centauri's chemistry and motion in the galaxy is also consistent with this picture.

Needless to say that Omega Centauri is a very peculiar globular cluster, a beauty either to be imaged or visually seen at the telscope.

This time I imaged Omega with the Quattro, an ultra fast scope, getting a substantial reduction of the integration time, comparing with the last image that I took with a refractor f/7. Please see below.

This image is a stack as follows:

Lum: 20x100sec bin1x1

R,G,B: 10x 120sec bin 1x1

Telescope:

Skywatcher Quattro CF 10"

Camera: SX694 Trio

Mount: EQ-6 Pro guided

CCD Guider: Lodestar

Transparency was good. Seeing was good all over the session (FWHM from 2.1 to 2.5)

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
