NGC 5139 Omega Centauri Globular Cluster ( The Big Daddy of Clusters )

NGC 5139 Omega Centauri is the last object I imaged from my NexDome Obs last week
First time imaging this Globular Cluster with a bigger scope, 10" Newtonian ( previously using a 6" and 8" Newtonian )

Location: South Coast NSW, Australia
Sky : Bortle 3/4
Conditions : Average to good
No Moon
Telescope: 10" f5 klaus Helmerich Carbon Fibre Newtonian Reflector
Mount : Skywatcher EQ8-R Pro
Imaging Camera : ZWO2600MC
No Filter ( only internal UV/IR Cut protective window )
Guide Scope : Orion 60mm with helical focuser
Guide Camera : ZWO290MM
45 x 90 sec dithered subs
40 x Flats
60 x Bias
Tracking and Goto : EQMOD and Ascom Stellarium
PHD2 Multistar Guiding (0.60 to 0.70 arc sec total )
Stacking Software : Deep Sky Stacker
Post Processing Software : Startools V1.8 OSC Linear Data Set
Used Startools HDR module with "Tame" option to tame the core region and provide uniform brightness across the Cluster . Worked pretty well.

Comments welcome

Thanks for Looking

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.
