IC 1396

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.



Imaging data: Camera,

QHY8

- Filters, Baader 7nm H-alpha, Baader 8,5nm O-III and Baader 8nm S-II

- Optics, Tokina AT-X 300mm @ f2.8

- Exposures, 7X 1200s H-alpha, 8 X 1200 O-III and 3X1200s S-II + flats and bias

-

Guiding, LX200 GPS 12" + PHD-guiding and Lodestar
