I analyze #JWST data using code, with some manual adjustments such as co-registration of misaligned filters, and choosing whether to use log scale or not. My code is on GitHub. Here are some peeks. Below is a 100% automatic preview of NGC objects (mostly).

I am not sure this work is better than my bot's, but I did try to integrate all NIRCam data. I had to compromise the resolution, it was too much for my laptop to handle in full scale.
JWST 🔭: NASA, ESA, CSA, STScI.
A richly detailed infrared view of the star-forming complex N159 in the Large Magellanic Cloud. The frame is filled with thousands of tiny white and blue stars scattered across a dark field. Toward the center and right, large cloudy structures of gas and dust glow in shades of soft gray, blue, and warm orange. Filamentary wisps weave through the scene, outlining bubbles and cavities carved by stellar winds. Brighter knots of light mark young, newly forming stars embedded within the nebula. The overall appearance is a sprawling, textured landscape of turbulent interstellar material illuminated against the star-studded background

chatGPT: A composite image captured by the JWST NIRCam showing the NGC 185 galaxy. The image is divided into four quadrants, displaying a starry background filled with numerous galaxies, stars, and dust. The left side has a lighter hue, while the right side features a darker tone. Bright stars are visible, along with various small, faint objects scattered throughout the scene, highlighting the intricate details of this region in space.

Infrared image of the edge-on spiral galaxy NGC 4666, showing a bright, elongated central disk filled with clusters of white and pale blue star-forming regions. Darker dust lanes weave through the galaxy’s mid-plane, while warm reddish and cool bluish tones blend toward the outer halo. The galaxy sits against a dark background speckled with faint stars and distant galaxies

Three #NASAWebb discoveries in ONE! Webb shows there are FOUR dust shells (only one was previously seen), allowing researchers to narrow the stars’ orbit of one another to a LONG 190 years. Plus, they confirmed a third star is part of the “party”: https://bit.ly/4n1tpas 🔭 🧪

#JWST 🔭 NIRCam data for NGC-2440
A planetary nebula, a dying star shedding material
NASA, ESA, CSA, STScI
chatGPT: Infrared image of the planetary nebula NGC 2440, showing a brilliant, chaotic structure surrounding a dying star at its center. Twin lobes of gas and dust expand outward in a butterfly-like shape, glowing in shades of red, green, and violet. The star’s intense light radiates through the nebula’s translucent filaments, revealing layered shells of ejected material. Surrounding the nebula, a dense field of golden and white stars fills the background, scattered across the dark expanse of space.

technical: #JWST 🔭 data comes in .fits files with 10 objects, where only the first (header) and second (data) are useful for me. While it is easy to download the header with fitsheader, it is tricky to download the data itself.
I use astropy with use_fsspec to do that but sometimes it fills RAM, >

V* V2455 Ori outflows in rings. Take this in different IR hues that #JWST 🔭 gives us, and you get a candidate for the most beautiful corners of our galaxy.
chatGPT: A vivid infrared view of the star-forming region HOPS-108. At the center, a brilliant yellow-white newborn star shines with intense diffraction spikes, surrounded by glowing clouds of gas and dust. Wisps of purple, blue, and orange flow outward in curved arcs, tracing powerful jets of material ejected from the young star. The surrounding nebula glows in iridescent layers, with cooler blue regions blending into warmer gold and magenta tones. Numerous smaller stars sparkle across the frame against a deep, cosmic blue background.
