"Eight-Panel Mosaic Of M31: Stars, Nebulae And Central Bulge" By Chuhong Yu, Jingyao Hong, Xi Zhu, Yaguang Wan
"This image shows countless resolved stars, emission nebula and a mysterious central bulge. The photo is incredibly detailed, the mist surrounding the galaxy is actually tens of thousands of yellowish tiny stars.
PixInsight and AstroPixelProcessor were used for pre-processing and the mosaic. Defects were corrected using a technique called Multi-Scale Gradient Removal, using wide-field data. During the process, BlurXTerminator, StarXTerminator and NoiseXTerminator were used and the final adjustment was done in Photoshop."

"Electric Threads Of The Lightning Spaghetti Nebula" By Shaoyu Zhang
"This full-spectrum image of the Spaghetti Nebula unveils the faint and elusive nature of this supernova remnant (SNR), hidden behind a vast cloud of dust that obstructs its emission light. To enhance its visual appeal, Shaoyu Zhang dedicated considerable time to capturing OIII data, intensifying the blue and green hues, while allowing SII and H-alpha to support high dynamic range stretching for added depth."

"Neon Sun" By Peter Ward
"The data from NASA’s Solar Dynamics Observer (SDO) probe was used here to show the Sun’s inner corona in a way that hints at a process that is similar to that which energises colourful neon lights on Earth.
Images taken by the SDO in the ultraviolet spectrum (at 171, 193 and 304 nm) were re-mapped to a more vibrant palette, with the same coronal data turned ‘inside out’ to surround the Sun, creating the illusion of it being enclosed in a neon tube.
While neon tubes use electrical current to cause the low-pressure gas within them to glow, it is the heat from nuclear fusion that ionises the gas of the Sun’s atmosphere. While this ultraviolet light is undetectable to human eyes, it can easily cause sunburn on unprotected human skin within just few minutes of exposure.
Remapped in Photoshop, the data was then polar inversed to mirror the inner coronal image. Colour saturation was increased by around 30 per cent and given one pass of a noise reduction filter."
