Located about 5,200 lightyears from Earth, the "Rosette" nebula (sometimes referred to as the "skull" nebula) is an enormous star-forming region 10,000 times the mass of our Sun. Being such a popular target in astrophotography, I wanted to devote as much time and care as I could to capturing and processing it, to hopefully bring a uniquely artistic view of this incredible part of our Milky Way.
So, this was my first project with the new Askar Color Magic E2 Sii/Oiii filter. I'm stunned by the results! In combination with the Optolong L-Ultimate filter, I've been able to closely simulate a monochrome camera setup with my ASI2600MC.
