NGC 5128 Centaurus A Galaxy during a Heat Wave

Location : Backyard Sydney, Australia
No Moon
Sky Glow : Bortle 7 to 8 City Suburban
Conditions : Poor seeing and transparency ( high humidity , high temperature 29 deg C or 84 fahrenheit at 11.00pm ) Stars scintillating ( Sydney was experiencing a rare early Autumn 2 week heat wave with daytime temperatures of 35 deg C to 38 deg C )
Telescope : 6" f6 GSO Newtonian Reflector
Mount : Skywatcher EQ6-R Pro
Imaging Camera : ZWO 2600MC , cooled to - 9.0 C maxed out , Gain 101
TS Optics GPU Coma Corrector
No Filters ( only internal protective window UV/IR Cut of 2600MC )
122 x 60 sec dithered guided Subs ( 2 hrs )
40 x Flats
60 x Bias
PHD2 Multistar Guiding ( 0.70 to 0.80 arc sec total )
Goto and Tracking : EQMOD and Ascom Stellarium
Deep Sky Stacker
Processed in Startools V1.8 ( Data set loaded via centre option " Linear with Bayer not white balanced" )

Due to conditions and heavy LP , 2 hours of broadband data ( 60 sec lucky imaging ) was no where near enough to produce a quality image but managed to process some sort of image in the end. I was hoping for 4 to 6 hours or more over a couple of nights. The heat was relentless ...........

Thanks for looking
Comments most welcome

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.
