Start of the new project, IC 405 closeup
IC 405, Sh2-229 or Caldwell 31 also known as the "Flaming Star Nebula".
RA 05h 16.2m dec +34° 28′
Image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
IC 405 locates in constellation Auriga and it's an emission/reflection nebula. Refelction component can't be seen in my image, since I'm shooting only narrowband data and reflection part is broadband target.
Distance from Oulu, Finland, is about 1500 light years. Nebula is about 5 light years across.
Colors are borrowed from this older image. I'll shoot better color channels and more H-alpha light,
when ever weather allow me to do so.
Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission. This composition is very close to a visual spectrum.
