Rosette Nebula closeup




Rosette Nebula & a star cluster NGC 2239


Nebula in HST-palette, Red=S-II, Green=H-a and Blue=O-III



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.


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

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.


I reprocessed all the data for this, beautifu, largish and very dim, planetary nebula.PK 164+31.1, sometimes known as a "Jones-Emberson 1" has an angular diameter of 6', 67" x 6', 67" and it locates in constellation Lynx. Distance from my home town Oulu, Finland, is about 1600 light years.
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.

IC 443 finalized


A cosmic A-Bomb

I named this image of IC 443 to a "Cosmic A-Bomb" since it looks like a gigant explosion. In fact, it is a remnant of a gigant nuclear explosion, Supernova.


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.


Nebula in HST-palette, Red=S-II, Green=H-a and Blue=O-III

Generally this was on of the moust difficult object to shot in longer focal lenght. Surface brightness is very low and there is extremely faint nebulosity around a main object. I wanted to show it and a detailed filaments of the supernova remnant main body. The actual remnant is much large, than my limited field of view can show.
 
An older wide field image of the IC 443 from a Spring season 2009.
Exposures:
-H-alpha 8x1200s binned 1x1
-S-II 4x600s binned 2x2
-O-III 5x600s binned 2x2
Optics: Tokina 300mm TX f2.8 @ f2.8
Camera: QHY9 @ -50 C
Guiding: Lx200 GPS 12" + LQHY5 and PHD-Guiding

I think, this was as hard object as a Sh2-240 (Simeis 147), Supernova remnant in Taurus. I shot it in last Spring season;  http://astroanarchy.blogspot.com/2009/01/sh2-240-more-lights.html

I found out, that color, in my older wide field image, is very usable for this new closeup version! There is not much details in very dim O-III and S-II channels- I use a method of mine, Tone Mapping, to make a color composition from images with a very different scale. It works just fine!

IC 443, a prewiev version in HST-palette


IC 443, HST-palette

I have shot this target with much wider field last year;
http://astroanarchy.blogspot.com/2009/02/ic443-in-hst-palette.html I took colors from this image and use them with my new H-alpha channel to build a kind of prewiev version of narrowband color image.

When weather allows, I'll shoot better color channels with a native focal lenght.

Planetary Nebula, PK 164+31.1, more lights


Nebula in HST-palette, Red=S-II, Green=H-a and Blue=O-III

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.

At the same time as I was imaging IC 443 in prevoius post, I shot more lights for this dim planetary in Constellation Lynx, since IC 433 was too low after midnight.

Due the low brightness this objet is not commonly imaged, even though it has a largish angular diameter to a planetary nebula. (6'.67" x 6'.67")

IC 443, project continues

H-alpha channel


H-alpha channel in false color ( It emits Red light at wavelength of 656,28 nm.)

This winter has been very cloudy, up here 65N. Those few clear nights has been very cold, temperatur has dopped to -30 celsius at many nights. I have used every oportunity to shoot various target, even though extereme low temperature does no good to my equipment nor me.

Now I have collected as much H-a light to this Supernova remnant as I could. I have had, ones again, many problems with my scope and other eguipments doe the weather and other various reasons.
In previous post, there is this target with less than two hours of exposure time, now I have shot much more exposures to have higher S/N. This will need even more time, but this season is not long enough for that and I'll like to shoot O-III and S-II channels too to make a narrowband color composition out of them.

Here is a wider field IC 443, from February 2009, imaged with a Tokina AT-X 300mm camera optics:

Starting a new project, IC 443

A cosmic A-bomb

Last night I started a new imaging project with the IC 443, supernova remnant in Gemini.
Not a very promicing start though, I got less than two hours of usable data after spending whole night shooting it. There was lots of thin upper clouds and they ruined majority of my frames. I'll shoot more H-a, maybe 6-7 hours, Sulfur and Oxygen as well.

I will test a new imaging system with this objet, I call it "VARE" Variable Resolution imaging. The idea is shoot part of the data binned 1x1, like an example here, and rest of it binned down to 2x2 - 4x4.
By that way, I can use high S/N details from a 1x1 binned image and low S/N areas from other bin modes.
Using binning is basicly same as use of the faster optical configuration, I have much greater sensitivity at cost of resolution. For example if I bin camera down 3x3, I have allmoust nine times more sensitivity!
I will write a tutorial about VARE-method, after I have tested it.

Planetary Nebula in Constellation Lynx


Nebula in a HST-palette (Hubble Space Telescope)
Red=S-II, Green=H-alpha and Blue=O-III


Nebula in natural colors from same material as a HST-image. 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.

Finally, after a long period of bad weather, I was able to shoot more H-a, O-III and S-II channels.
Seeing was not too bad but the transparency was very poor. This is an object with a very low surface brightness and bad transparency eated out some signal.

Due the low brightness this objet is not commonly imaged, even though it has a largish angular diameter to a planetary nebula. (6'.67" x 6'.67")

Astro photographing in Finland

This it is...
Lots of snow and clouds in winter 2010.

I bet, if I'll start to shoot snow and clouds, we dont see them anymore.

3D-models from 2D-astro images, more testing

In this blog, there is lots of experimental material. To see my actual astroimages, please, see my Portfolio: http://astroanarchy.zenfolio.com/

Links to the original images are with animated models, there is links to other 3D-formats as well.
Animations are made by creating artificial parallax to an image. Then two images are animated together by using a very clever webservice. 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!

I made an animated 3D-presentation from the Cat's Eye nebula too.
Since threre was difficulties with a star field around it, I removed all other stars but the central star of the nebula. The spherical nature of this planetary nebula can be now seen without eye tricks, like in a stereo pair.
