Rosette Nebula closeup as an animated stereo pair
In this blog, there is lots of experimental material. To see my actual astroimages, please, see my Portfolio: http://astroanarchy.zenfolio.com/
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!

NOTE! This is a personal vision about forms and shapes, based on some known facts and artistic impression. Viewing instructions can be found from a Right hand side menu.

An anaglyph Red/Cyan version.
You'll need Red/Cyan Eyeglasses to be able to see images right. Note, if you have a Red and Green filters, you can use them! Red goes to Left eye.

Rosette Nebula closeup
Rosette Nebula & a star cluster NGC 2239
Nebula in HST-palette, Red=S-II, Green=H-a and Blue=O-III
Last two nights I used for the Rosette nebula, weather gets cloudy after the midnight at both evenings.
I was positively surprised about the image quality since Rosette Nebula doesn't raise very high up here North, the maximum elevation is about 30 degrees, seeing and transparency were both lousy too.
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations.
Levels, curves and color combine in PS CS3.
Telescope, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO @ 9Hz
Image Scale, 0,75 arcseconds/pixel
Exposures
H-alpha 13x1200s, binned 1x1
Note.
Other channels are from a wide field image from 2009:

Planetary Nebula, PK 164+31.1, finalized
Jones-Emberson 1
Nebula in natural color. Narrowband channels are mixed to match visible spectrum. Red=80% H-alpha+20% S-II, Green=O-III and Blue=80% O-III+20% H-alpha to compensate otherwise missing H-beta.
The tiny Blue central star is a white dwarf, the intense ultraviolet light emitted by this star makes elements in a ring glow. Ionized Hydrogen emits red light and the ionized Oxygen blue one.
Why the name "PK 164+31.1"?
PK comes from the names of Czechoslovakian astronomers Perek and Kouhutec. 1967 they created an extensive catalog of all of the known planetary nebulae in 1964. The number indicates the position in the sky. The alternative name "Jones-Emberson 1" is after its discoveres.
