NGC 1499 closeup as an Anaglyph Red/Cyan 3D
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!

NGC 1499, the "California Nebula", a closeup
NGC 1499, the "California Nebula" locates in constellation Perseus. Distance is about 1000 light years.
This is a closeup image, the actual nebula covers about 2,5 degrees of sky.
RA 04h 03m 18.00s Dec +36° 25′ 18.0"
The image is in HST-palette, (HST=Hubble Space Telescope)
from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen.
I have shot this image as a wide field version before. For this closeup I shot 27x1200s, binned down 2x2, for H-alpha channel, colors are from my older wide field image. NGC 1499 has a very low surface brightness, hence a longish integration time is needed.
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.
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.
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9 Guiding, SXV-AO @ 4,5Hz
Image Scale, 0,75 arcseconds/pixel
Baader H-alpha 7nm 27x1200s, binned 2x2
Older wide field version of IC 405 from 2008 is used for colors.
Original Blog post and details:
This image was published at July 2009 issue of Sky & Telescope magazine's Gallery, in page 78,
there is a full page image of NGC 1499, the "California Nebula" by me.
Total exposure time is 18 hours.
