NGC-3576 HaHOO

Learning what drizzle does... I gave this dataset a 2x drizzle with a drop shrink of 0.75 This has resulted in data that looks quite good!

I thought I'd process this one by splitting the RGB channels, Taking the R as Ha, then blending the G and B channels at (G*0.7) + (B*0.3) to create the OIII.

The following process was applied

Clone the Ha data as Lum
Recombine as Ha OIII OIII
run BXT on HOO (default settings)
run BXT on Ha data (increasing sharpen non-stellar a little)
NXT on both (0.8 denoise, 0.15 detail)
Light GHS to bring up the data, leaving the data relatively flat and boring
SXT on HOO and Ha images, keeping the star image from HOO, but discarding the Ha stars.
Sharpening done to Ha data
Further GHS and curves adjustment to push the Ha data contrast and nebulosity extension.
LRGB combine to add the Ha data as the Lum to the HOO
Some selective (colour masked) curves adjustments to colour in the starless image
Pushed saturation in the stars image.
Re-screened stars.
Star size reduction.
Dark Structure Enhance

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.
