With beautiful colouring and sparkling stars, Ian Barredo’s composition of Messier 82 has won the August 2020 edition of the RASC Robotic Telescope editing contest.
August’s image was Messier 82, also known as NGC 3034 or the Cigar Galaxy. According to NASA, the magnificent starburst galaxy sees young stars that are being born in its centre 10 times faster than they are inside our entire Milky Way Galaxy. This creates a huge concentration of young stars and a fierce galactic superwind.
Using the RASC Robotic Telescope files of M82 in HaLRGB, Barredo said he stacked and calibrated the image in Astro Pixel Processor. He said individual stacks of Ha, L, R, G and B were combined using the HaLRGB tool in Astro Pixel Processor.
He worked on background neutralization and star colour calibration, and he adjusted the final curves and saturation in Adobe Photoshop.
September 2020’s target
This month, the RASC RTScope editing contest target is the Helix Nebula, or NGC 7293.
Located about 650 light-years away in the constellation of Aquarius, NASA writes that the nebula is a typical example of a class of objects called planetary nebulae. Planetary nebulae develop from the remains of stars that once looked like our Sun — shedding gaseous layers, they leave behind a tiny, hot, dense white dwarf core that lights up the surrounding gases.
