NGC 1499, reprocessed
I did reprocessed this nebula since my skills are much better now, than two years ago.
All the exposures I have taken for this object are used. Total exposure time is now about 20h together.
Two camera lenses was used to capture the data, a Tokina AT 300mm f2.8 and a Canon EF 200mm f1.8, both lenses was used at full aperture.
NGC 1499, the "California Nebula" locates in constellation Perseus. Distance is about 1000 light years.
The nebula covers about 2,5 degrees of sky.
RA 04h 03m 18.00s Dec +36° 25′ 18.0"
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.
HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
Narrowband data was used for Star colors this time, mixture of channels was the same as in first "natural" color composition image here.
There is a formation at Seven a clock, kind of half circle, it might be an old uncategorized planetary nebula?

You'll need Red/Cyan Eyeglasses to be able to see this image right.
Note, if you have a Red and Blue filters, you can use them! Red goes to Left eye.

NGC 1499 as an animated 3D
Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.
Please, let the images load for few seconds to see them animated!
