Hi everyone, after processing the Rosetta in Hubble Palette I have created a two-colour version with the data collected by my telescope combined with those of my astrophotographer friend Riccardo Pacini astrophotography .
The Rosetta Nebula (also known by its catalogue numbers NGC 2237 and C 49) is a large, roughly circular H II region located at the edge of a giant molecular cloud in the constellation Unicorn.
The nebula has an angular diameter of 1.3° and lies at a distance of 1600 parsecs (about 5200 light years) from the Solar System; it is about 100 light years in size. At the centre of the Rosetta Nebula is a bright open cluster known as NGC 2244.
