An emission nebula NGC 1491
A start of the new imaging project.
I'll shoot other two emission channels, needed for a color image, as soon as the weather allows.
NGC 1491
in constellation Perseus
NGC 1491 in H-alpha emission light
INFO
A closeup
A detail from the center of the image above
A popular shape in our local universe
While processing the image, I noticed a familiar shape in the center portion of the image.
It seems to repeat itself in various targets. My guess is, that it's coursed by the solar wind from the open cluster usually locates in center of the emission nebula of this type.
A collection of targets with same type of shapes as can be seen in center of the this new image.
The top most two images are from NGC 1491.
Technical details:
Processing work flow:
Image acquisition, MaxiDL v5.07.
Stacked and calibrated in CCDStack2.
Levels, curves and color combine in PS CS3.
Optics, Meade LX200 GPS 12" @ f5
Camera, QHY9
Guiding, SXV-AO, an active optics unit, and Lodestar guide camera 5Hz
Image Scale, ~0,8 arc-seconds/pixel
21 x 1200s exposures for the H-alpha, emission of ionized Hydrogen = 7h
An experimental starless image

Melotte 15 as an experimental 3D-study
I have done several 3D-studies out of my astronomical images. Models are based on some known scientific facts and an artistic impression. This is an approximation to the real structure of the nebula, an educated guess, it gives a feel to the object and an idea, what it must really be like.
There are several 3D-modes to see from the same material. Animated 3D, free view stereo pairs and an anaglyph Red/Cyan 3D.

Please, let the animation load to see a smooth movement
There are nothing else used than a real image elements from the original 2D-shot!

Pair of Red/Cyan eyeglasses are needed to see this 3d-image!
(Red and Blue filters will do the trick, red goes to left eye.)
Ps.
All my 3D-studies, stereo pairs and an anaglyph 3D, can be found here:

Astro Anarchy gets published, a public Slide Show
My works are selected as a public content for a pedestrian zone in my home town Oulu, Finland.
There is a very large display unit at the end of the zone, 5.12 x 3.2 meters (over 16 x 10 feet). Five different sets of my astronomical photographs are running there as a slide show at January 2013.
