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.



Total exposure time is about 12h







Technical details:







Processing work flow:



Image acquisition, MaxiDL v5.07.



Stacked and calibrated in CCDStack.



Deconvolution with a CCDSharp, 30 iterations, 50% mix..



Levels, curves and color combine in PS CS3.
