Eight-Burst Nebula, fusion between NIRcam and MIRI to reveal the binary star system (Benoit Blanco)

Eight-Burst Nebula, fusion between NIRcam and MIRI to reveal the binary star system

NGC3132, Caldwell 74.

I wanted to merge the nice details from NIRcam, and the visible binary star system from MIRI.
I made a starless NIRcam image with Starnet, extracted the stars from MIRI and combined them.
I'm not very happy with the result, denoise and linear pattern needs to be stronger ; stars are looking weird. JWST's data are very challenging.

Processing sequence NIRcam:
Linear Pattern Subtraction, Mure denoise, DBE, Star alignement, Superstack NoRejection, TGV, Deconvolution, GHS stretch, Local Histogram, Curves, Starnet V2, cosmetics. RGB as:
Red: f470w
Olive: f444w
Orange: f356w
Gold: f212n
Cyan: f187n
Blue: f090w
LRGB with Superstack as luminance.

Processing sequence MIRI:
Linear Pattern Subtraction, Mure denoise, RGB, DBE, ColorCal, ACDNR, Dynamic alignement on NIRcam, StarnetV2 to get the stars.

Photoshop merge by superposition of MIRI’s stars on NIRcam LRGB image.

This image was created with Webb data from proposal 2733.

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.
