Astronomers for Planet Earth are submitting a statement about some of the proposed megaconstellations that would ruin ground-based astronomy to the FCC.
You can read the statement below: 🔭☄️
Signed! - I was just a bit confused by the wording of the first paragraph.
Do I need to become an A4E member before signing the statement?

An orange jet consisting out of clumps coming from the nucleus. The jet has a bent on it. The host galaxy is blue and is an ongoing merger of two galxies. A small blue galaxy is below the main galaxy pair. Other red galaxies and a blue star are also in the image.

Thanks, that certainly changes the equation.
I guess your original explanation must have been right then.
So I believe the left image actually shows real colors, whether it had additional upscaling applied I don't know. Maybe the pixel size could be measured.
As for the reason why Vantor would only share a low resolution greyscale version if they have better versions available I don't know...
Vantor (back when they were still called Maxar) developed their opwn AI upscaling that's marketed as 15cm HD imagery.
And as far as I know all their satellites are capable of color imaging (correct me if I'm wrong).

AI writing is like store-bought cake. It might be perfectly fine, maybe even as good as something you could make yourself, but it’s weird to give it to someone and say it’s homemade
Thanks Aurélien!

The first image off my camera of the Blood Moon. This is right at totality, 3:33 a.m. I did very little processing on this. I sharpened it. The light and color are exactly as they came off my camera. #astronomy #astrophotography

Satellite photo of the Namib Desert. The top two-thirds are covered in red, undulated sand dunes, leading down to a dry river bed, seen in bands of blue and white. Along the river bed, black dots of vegetation curl around the pointed tips of dunes.
#PPOD: Korea’s Kompsat-2 satellite captured this image over the sand seas of the Namib Desert on 7 January 2012. The blue-and-white area is the dry riverbed of the Tsauchab. Black dots of vegetation are concentrated close to the river’s main route, while salt deposits appear bright white. 🧪

Nice work! I also like the color/filter indicator.
Maybe you could add the program ID to your image description so one can find out more about the image and when it was taken :)

filters: f164n, f212n, f356w, f405n.
I played with the colors; if I followed the sequence of each filter like the Nircam chart, I didn't like the result.

On March 31, 2005, just minutes after the Cassini spacecraft's closest approach to Titan during the Titan (T-4) Flyby, Cassini viewed Saturn peeking through Titan's thick atmosphere. Saturn's rings are seen here casting dark, dramatic shadows across the planet's northern disk (upper left). This composite is made of images that were taken by the Cassini spacecraft's camera system, the Imaging Science Subsystem (ISS) on March 31, 2005 and received on Earth April 1, 2005. Cassini was approximately 1,200,000 km away from Saturn and 7,000 km away from Titan. The images were taken using red, green, and blue filters. Credit: NASA / JPL / SSI / Ian Regan / Val Klavans

This Image of the Week of the NGC 1269 galaxy was taken utilizing the Department of Energy-fabricated Dark Energy Camera (DECam), which is mounted on the U.S. National Science Foundation Víctor M. Blanco 4-meter Telescope at NSF Cerro Tololo Inter-American Observatory, a Program of NSF NOIRLab. NGC 1269 is an early-type spiral galaxy located about 33 million light-years from Earth in the constellation Eridanus. A bar, a feature common to many spiral galaxies, slices through the center of the galaxy. Surrounding the galactic core are both inner and outer disks, seeming to form ‘wheels’ around the core. Their presence is thought to be the result of a merger with another galaxy, and the inner disk is also believed to have been further shaped by density waves radiating outward from the galactic center. Data for this image came from the archive of the Dark Energy Survey (DES), operated by the DOE and NSF between 2013 and 2019 with the specially-designed DECam. The survey sought to study the nature of the elusive dark matter by imaging hundreds of millions of galaxies. Today, the DECam is available to other scientists for use on the Blanco telescope.

It was processed from RAW EDR images from the PDS and gamma adjusted to create a realistic representation of brightness and contrast. This version of the image was colorized using a mosaic of RDCAM images and Aster Cowart's Jezero Crater mosaic (flic.kr/p/2kymR7f) to create an authentic color representation how the descent would have looked to the human eye.
