Map of Mars in true colors: images from Mars Express were projected by Michael et al. (2024) and post-processed with TrueColorTools. TCT used the Tikhonov regularization to reconstruct a spectral cube from four High Resolution Stereo Camera (HRSC) channels and simulated human perception of it. [1/3]

Recently updated Cylindrical Texture Calibrator, a Python utility with a GUI that was developed to help the @celestiaproject.bsky.social community with ongoing updates (we need more devs, by the way!). I've included some interesting details in the thread. [1/5]

I present three maps of Titan: one in visible "true" colors (albedo scaled and gamma corrected), one in enhanced colors (linear albedo scale with a factor of five), and one of the lakes. In this thread, I will briefly describe how the impenetrable haze was bypassed.

Ganymede in 1979 from Voyager 2 (mosaic) true color, processed from the raw data using @askaniy.bsky.social's TrueColorTools I used 9 OGBV frames for this processing. the edge of the disk is slightly cut off, so a small rendered view was inserted and spliced in. manual processing took ~3.5 hours 🧪🔭

Now published in AJ! Get in here this system is crazy iopscience.iop.org/article/10.3...

Giant planets orbiting red dwarfs are uncommon, as are hot Neptunes ("Neptunian desert"), as are exoplanets in polar orbits. On this painting, the host star "observes" its strange planet through a massive polar dark spot. [1/9] of the "art research" thread on TOI-3884 and "red" dwarfs in general.

Reflectance colors of 3I/ATLAS in sRGB color space with illuminant E (assuming 0.5 albedo, it's very likely lower)

Voyager 1, WAC. March 4, 1979. Photos in violet, blue, and orange filters were aligned, reconstructed into a spectral cube, and convolved in sRGB color space with Illuminant E. There are gamma-corrected and contrast-enhanced options. Done with my program github.com/Askaniy/TrueColorTools

Artistic representation of Epsilon Eridani b, also known as AEgir [sic]

Emsenhuber et al. 2024 (DOI 10.3847/PSJ/ad2178) obtained a population of collision outcomes (2 bodies with m<10⁻² M⊕) that form a contact binary. Structure is maintained by material strength and spin. The painted peanut is Pluto-sized in length, but the size of Mars is theoretically achievable.

An attempt to (relatively) realistically paint a hot Jupiter with a quasi-closed type of atmosphere, according to Bisikalo et al. 2021. (ui.adsabs.harvard.edu/abs/2021PhyU...)

I'm developing an open source program with GUI that stores a variety of space photometry and converts them to color, TrueColorTools. It can also process images and generate color charts. Here's the latest table of some featured objects (geometric albedo mode, sRGB color space, Illuminant E)
